Best Free AI APIs and Coding Tools

ML model hub. Since 2026-10-07, free accounts get no included Inference Providers credits: free users buy credits or upgrade to PRO to call Inference Providers, which serves 200+ models. PRO ($9/month) gets $2.00 a month. Free accounts get 100GB of private storage and best-effort public storage; substantial storage needs PRO, Team or Enterprise.

• A free Hugging Face account needs purchased credits, which take a payment method, to call Inference Providers. (From huggingface.co/docs/inference-providers/pricing, read 2026-10-22.)

Fast LLM inference on Groq's LPU hardware. Free plan: gpt-oss-20b, gpt-oss-120b and Qwen3.8 27B, each at 30 requests a minute, 1,000 requests and 200,000 tokens a day, plus Whisper speech-to-text at 2,000 requests a day. Each of the three free models is also limited to 8,000 tokens a minute, and Groq applies whichever limit is reached first. Whisper is also limited to 20 requests a minute, 7,200 audio seconds an hour and 28,800 audio seconds (8 hours of audio) a day. On the free plan, gpt-oss-safeguard-20b is limited to 3 requests a minute, 1,000 requests a day, 2,000 tokens a minute and 200,000 tokens a day. Qwen3.8 27B, gpt-oss-safeguard-20b, Orpheus Arabic Saudi and Orpheus V1 English are Preview models. Groq says Preview models "are intended for evaluation purposes only and should not be used in production environments as they may be discontinued at short notice". Llama 3.3 70B and Llama 3.1 8B left the free and developer plans on 2026-08-16 and are Enterprise-only. Orpheus text-to-speech (English and Saudi Arabic) is also on the free plan, at 10 requests a minute, 100 requests and 3,600 tokens a day. Developer plan prices per 1M tokens: gpt-oss-120b $0.15/$0.60; gpt-oss-20b $0.075/$0.30; Qwen3.8 27B $0.80/$4.00. The Batch API costs 50% less and returns results within 24 hours to 7 days, without impacting standard rate limits. When requests to gpt-oss-20b, gpt-oss-120b or gpt-oss-safeguard-20b start with the same text as a recent request, Groq caches that part automatically and bills those input tokens 50% less. The batch discount does not stack with prompt caching discounts; all batch tokens are billed at the batch rate regardless of cache status. Orpheus text-to-speech costs $22 per 1M characters in English and $40 in Saudi Arabic. Groq's API is OpenAI-compatible at the base URL https://api.groq.com/openai/v1. The free models' API model IDs are openai/gpt-oss-120b, openai/gpt-oss-20b and qwen/qwen3.8-27b.

• Groq rate limits apply to the whole organization, not per user or API key. A request over the limit returns a 429 Too Many Requests error. Cached tokens do not count toward rate limits. (From console.groq.com/docs/rate-limits, read 2026-11-04.)
• You are billed only after you add a payment method and move to the paid Developer tier. (From console.groq.com/docs/billing-faqs, read 2026-10-05.)
• Groq's Services Agreement does not permit it to train or fine-tune models on your inputs or outputs unless you give permission. (From console.groq.com/docs/legal/services-agreement, read 2026-10-05.)
• Groq's Services Agreement grants use of Groq APIs to integrate its services into customer applications for end users. Its restrictions do not prohibit commercial use. (From console.groq.com/docs/legal/services-agreement, read 2026-10-29.)

Free tier: Gemini 4 Hydrogen, Gemini 3.8 Flash, 3.6 Flash, 3.5 Flash-Lite, 3.1 Flash-Lite, Gemini 3 Flash Preview, Gemini Embedding 2 and Gemma 4 are free of charge. Also free of charge are Gemini 3.8 Live (real-time voice), Gemini 3.5 Live Translate (translation), Gemini 3.5 Transcribe (speech-to-text), Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS (text-to-speech). Gemini Decision (gemini-decision-1), released 2026-11-11, is a multimodal decision model available through the Decisions API. It answers yes/no, choice and rubric questions with probabilities and generates zero output tokens, so it has no output price; input is free of charge on the free tier with 10,000 requests per day, and $0.10 per million input tokens on the paid tier. Gemini 4 Hydrogen (gemini-4-hydrogen), released 2026-11-12, is free of charge on the Gemini API free tier for input, output and context caching. On the paid tier, Gemini 4 Hydrogen costs $1.50 per million input tokens and $7.50 per million output tokens (output includes thinking tokens), with context caching at $0.075 (implicit caching only); on the Batch API, Gemini 4 Hydrogen is $0.75 input and $3.75 output. The other Gemini 4 models, Gemini 4 Carbon (gemini-4-carbon) and Gemini 4 Argon (gemini-4-argon), are paid only, as are Gemini 3.1 Pro Preview and Gemini Omni 1.2 Flash (gemini-omni-1.2-flash). Gemini 4 Carbon, which Google calls its most capable reasoning model, has been generally available since 2026-11-10 and is not available on the Gemini API free tier. Gemini 4 Argon, generally available since 2026-10-13, is not available on the Gemini API free tier. According to ai.google.dev/gemini-api/docs/google-ai-plans, "Gemini 4 Argon is not available on the Free plan." Gemini 4 Argon is available through the Gemini API on the paid tier. "Direct use of the Gemini API (such as using API keys or external applications) is billed and managed separately," per ai.google.dev/gemini-api/docs/google-ai-plans. Google AI Pro and Ultra provide access to Gemini 4 Argon in Google AI Studio, per ai.google.dev/gemini-api/docs/google-ai-plans. Gemini 4 Argon is in Antigravity on Google AI Ultra and paid Google AI Pro. In Google AI Studio, Gemini 4 Carbon requires a Google AI Ultra plan and is not available on the Free or Google AI Pro plans (aistudio.google.com/docs/google-ai-plans). In Antigravity, Gemini 4 Carbon is available on Google AI Ultra and Enterprise only (antigravity.google/docs/models). On a Google AI Pro trial, Argon is only available "on trial with eligible premium devices" (antigravity.google/docs/models). Claude Opus 5.5 and Claude Sonnet 5.5 are not included on Google AI Pro trials; trial users and those with memberships through third-party partners, Pixel Pass or Google Fi manage subscriptions through Google One. Google AI Pro via partner offers like Jio's does not include Gemini 4 Argon, Claude Sonnet 5.5 or Claude Opus 5.5 in Antigravity. Per a Google staff member on discuss.ai.google.dev (2026-10-21), "Those frontier models are restricted to directly billed (non-trial/non-promotional) Google AI Pro, Google AI Ultra and Enterprise plans." No Gemini image model has a free tier in the API. Nano Banana 2.1 (gemini-nano-banana-2.1) became generally available on 2026-10-06. It costs $0.0336 per 1K image, $0.0504 per 2K image and $0.113 per 4K image. The Batch API halves those prices. Nano Banana Pro costs $0.134 per 1K or 2K image and $0.24 per 4K image. Except for Gemini Decision, Google publishes no free-tier rate limits; each project's limits are shown in Google AI Studio. Developers report 429 errors showing 20 requests per day for Gemini 3.x Flash models and 500 requests per day for 3.x Flash-Lite models as of September 2026. Rate limits apply per project, not per API key. Daily request quotas reset at midnight Pacific time, per Google's rate-limits page. Since 2026-09-18 Google serves the Gemini 2.5 models only to users who have used them before, and points new projects to 3.5 Flash-Lite or 3.8 Flash. If your app calls gemini-3.7-flash, Google deprecated it on 2026-10-08. Requests to gemini-3.7-flash are routed automatically to gemini-3.8-flash. Google says to update the model string to gemini-3.8-flash. Google deprecated gemini-2.5-pro and gemini-2.5-flash on 2026-11-02. Both models shut down on 2026-12-01. Use them until that date. From that date, requests to gemini-2.5-pro route to gemini-3.8-flash and are billed at its rates. Requests to gemini-2.5-flash route to gemini-3.5-flash-lite and are billed at its rates. Update your model string before 2026-12-01 and review Google’s migration guides for breaking API changes. gemini-2.5-flash-lite is not deprecated. If your app calls Gemini 3.5 Flash (gemini-3.5-flash), Google deprecated it on 2026-10-08. Requests to gemini-3.5-flash are routed automatically to gemini-3.6-flash. Google says to update the model string to gemini-3.6-flash or gemini-3.8-flash. Google shut down Gemini Omni Flash Preview (gemini-omni-flash-preview) on 2026-10-22. Google's replacement is gemini-omni-1.2-flash. Google shuts down Gemini Omni 1.1 Flash (gemini-omni-1.1-flash) on December 3, 2026; after that, requests that name gemini-omni-1.1-flash are answered by gemini-omni-1.2-flash at Gemini Omni 1.2 Flash rates. Gemini 3.1 Flash-Lite (gemini-3.1-flash-lite) can be called until 2027-05-07, when Google shuts it down. Google's replacement is gemini-3.5-flash-lite. Paid, per million tokens (input/output; output prices include thinking tokens): Gemini 4 Carbon $2/$10 through 2026-11-30 (context caching $0.10, then $0.20, implicit caching only); Gemini 4 Argon $2/$10 through 2026-11-30 (context caching $0.10, then $0.20, implicit caching only); Gemini 3.8 Flash $0.75/$3.75 until 2026-12-31, then $1.50 input and $7.50 output from 2027-01-01 (3.6 Flash: the same prices and dates); Gemini 3.5 Flash-Lite $0.30/$2.50; Gemini 3.1 Flash-Lite $0.25/$1.50; Gemini 3.1 Pro Preview $2/$12 (prompts up to 200K tokens; prompts over 200K tokens cost $4 input and $18 output). Through 2026-11-30, Gemini 4 Argon's Standard output price is below Gemini 3.1 Pro Preview's for prompts up to 200K tokens, with the same input price; from 2026-12-01 Argon's is higher. From December 1, 2026, Gemini 4 Argon will cost $4 per million input tokens and $20 per million output tokens for Standard, $2 input and $10 output for Batch API, $2 input and $10 output for Flex, and $7.20 input and $36 output for Priority. From December 1, 2026, Gemini 4 Carbon will also cost $4 per million input tokens and $20 per million output tokens for Standard, $2 input and $10 output for Batch API and Flex, and $7.20 input and $36 output for Priority. The Batch API costs half the standard price; Gemini 3.8 Flash is $0.375 input and $1.875 output per million tokens through 2026-12-31. Gemini 4 Carbon and Gemini 4 Argon on the Batch API are $1 input and $5 output through 2026-11-30. Google also sells two tiers, Flex and Priority, both in Preview. A request picks one with the service_tier field ("flex" or "priority"); without it the request is Standard. Gemini 4 Carbon and Gemini 4 Argon on Flex are $1 input and $5 output through 2026-11-30; on Priority they are $3.60 input and $18 output through 2026-11-30. "The Gemini Flex API is an inference tier that offers a 50% cost reduction compared to standard rates, in exchange for variable latency and best-effort availability" (ai.google.dev/gemini-api/docs/flex-inference). "Priority inference is priced at 75-100% more than the standard API and billed per token" (ai.google.dev/gemini-api/docs/priority-inference). The Gemini API Contributor Tier is an invite-only private preview. Eligible users will be invited by email. It offers half the Standard price for Gemini 4 Carbon, Gemini 4 Argon, Gemini 3.1 Pro Preview, Gemini 3.8 Flash, and Gemini 3.5 Flash-Lite. Google uses the data from those models to improve its products. "Please don't submit sensitive or personal information" (ai.google.dev/gemini-api/docs/logs-policy). Grounding with Google Search is supported on the free tier for Gemini 3.8 Live, Gemini 3.8 Live Extended Thinking and Gemini 3.1 Flash Live Preview. It is not available on the free tier for Gemini 4 Hydrogen, Gemini 4 Argon or the Gemini 3.x Flash, Flash-Lite and Pro models. On the paid tier, 5,000 search requests a month are free, shared across Gemini 3 and newer models, then $14 per 1,000. Accounts opened after 2026-03-02 cannot spend the $300 Google Cloud welcome credit on the Gemini API.

• The Gemini API Free Tier needs no credit card or billing account; linking a billing account and prepaying moves you to the Paid Tier. (From ai.google.dev/gemini-api/docs/billing, read 2026-10-22.)
• Google's pricing page says free-tier content is used to improve Google's products. (From ai.google.dev/gemini-api/docs/pricing, read 2026-10-04.)
• For developers outside the European Economic Area, Switzerland and the United Kingdom, Google's terms say human reviewers may read free-tier prompts and responses, and Google says not to send sensitive, confidential or personal information on the free tier. (From ai.google.dev/gemini-api/terms, read 2026-10-04.)
• Paid-tier projects created on or after October 26, 2026, store Generate Content API requests and responses by default. Projects created before that date keep their existing Generate Content API storage setting, which is off unless it was turned on in AI Studio. The Interactions API stores requests by default in all projects, including projects created before October 26, 2026. The Paid Tier keeps stored interactions for 55 days and the Free Tier for 1 day. Logging also covers calls made through OpenAI compatibility endpoints. Logs are retained for up to 55 days, configurable to 7, 14 or 28 days. Logs are not used to improve Google's products unless shared. Logging can be toggled independently for each API in AI Studio, and store=false on a request turns it off for that request. (From ai.google.dev/gemini-api/docs/logs-policy, read 2026-11-06.)
• Apps that serve users in the European Economic Area, Switzerland or the United Kingdom may use only the paid tier. (From ai.google.dev/gemini-api/terms, read 2026-10-04.)
• Google's terms require users to be 18 years of age or older to use the Gemini API and Google AI Studio. The API may not be used in a website, app, or other service directed towards or likely to be accessed by individuals under 18. These rules apply to both the free and paid tiers. (From ai.google.dev/gemini-api/terms, read 2026-10-17.)
• Google offers the Gemini API and Google AI Studio, free and paid, in 230 countries and territories, including Taiwan, Brazil, Japan, Singapore, and the United Kingdom. China, Hong Kong, Macao, Russia, Belarus, and Iran are not among them. Google says to developers outside the list: "try the Gemini API in Gemini Enterprise Agent Platform". (From ai.google.dev/gemini-api/docs/available-regions, read 2026-10-17.)
• Google's terms say changes to Gemini API paid prices take effect 30 days after Google posts them unless Google specifies otherwise. Pricing for a new paid service takes effect immediately unless Google specifies otherwise. (From ai.google.dev/gemini-api/terms, read 2026-10-17.)
• Google is moving existing Postpay accounts to Prepay for Gemini API usage. An account that has not switched and added credits by the cutover date in its account notice has its paid service interrupted; other Google Cloud services on the billing account stay on Postpay. (From ai.google.dev/gemini-api/docs/billing, read 2026-10-07.)
• When the Prepay balance reaches $0, every API key in every project on the billing account stops working until credits are added; requests then fail with an HTTP 402 Payment Required error. (From ai.google.dev/gemini-api/docs/billing, read 2026-10-07.)
• The monthly Google Cloud credits from Google AI Pro or Ultra are eligible Google Cloud credits. On the Prepay billing plan, these credits pay for Gemini API usage only after you buy Prepay credits in AI Studio. With a $0 Prepay balance, requests fail even with unused Google Cloud credits, according to a Google staff member on discuss.ai.google.dev. (From discuss.ai.google.dev/t/error-code-402-message-your-prepayment-credits-are-depleted/185524, read 2026-10-10.)
• A paid project does not automatically revert to the free tier, even when its Prepay balance reaches $0. To use the free tier, disable billing on the project, which unlinks it from its billing account. (From ai.google.dev/gemini-api/docs/billing, read 2026-10-10.)
• Disabling billing on a Google Cloud project stops all other paid Google Cloud services in it. Some resources may be deleted and become non-recoverable. Outstanding charges are still due. (From cloud.google.com/billing/docs/how-to/modify-project, read 2026-10-10.)

Since about 2026-11-05, Mistral's Free plan covers Vibe and Studio and does not include API access. Creating API keys and calling the API require billing activation and pay-as-you-go with prepaid credits. Before then, Free mode let anyone create API keys with no credit card. The pricing page listed $10 a month of API credits on the Free plan until 2026-10-07. Mistral Pro costs $14.99 a month and includes $25.50 a month in API credits, shared across the API, Studio and Vibe Code. It included $30 a month until 2026-10-07. Verified students who have not used Vibe or Le Chat before can take the Education plan for $5.99 a month, for up to 12 months, with $15 a month in API credits. The Free plan has limited messages, web searches and coding sessions in Vibe. API prices: Ministral 3 (3B) $0.1/$0.1 (per 1M tokens); Mistral Small 4 $0.15/$0.6 (per 1M tokens); Mistral Large 3 $0.5/$1.5 (per 1M tokens); Mistral Large 4 (mistral-large-4; public preview since 2026-10-06, 1M-token context) $0.7/$2.1 (per 1M tokens); this price started on 2026-10-29; from 2026-10-20 until then, it was $1.36/$4.18; Mistral Medium 3.5 $1.5/$7.5 (per 1M tokens); Codestral $0.3/$0.9 (per 1M tokens). To call Mistral Large 4, use the model name mistral-large-4; mistral-large-latest still points to Mistral Large 3 (mistral-large-2512). Mistral Embed is $0.1 per 1M input tokens, and Codestral Embed is $0.15 per 1M input tokens. OCR 3 (mistral-ocr-2512) costs $2 per 1,000 pages and $3 per 1,000 annotated pages. OCR 4.1 (mistral-ocr-4-1) costs $4 per 1,000 pages and $5 per 1,000 annotated pages. OCR 3 remains available. Mistral Moderation 2 is free. Speech: Voxtral 3 models, released 2026-10-20: Voxtral Mini Transcribe 3 (batch) costs $0.0035 per minute of audio, Voxtral Small Transcribe 3 $0.004 per minute, Voxtral Mini Transcribe Realtime 3 $0.008 per minute, and Voxtral Speech 3 (text-to-speech) $13 per 1M characters. The earlier models are still offered: Voxtral Mini Transcribe 2 $0.003 per minute, Voxtral Mini Transcribe Realtime $0.006 per minute, and Voxtral TTS (text-to-speech) $16 per 1M characters. Mistral's voice agent API costs $0.04 per minute with Mistral Small 4 for reasoning, and $0.08 per minute with any other reasoning model. Mistral retired these models in 2026, and a request to a retired model fails with a 404 error: Mistral Large 2.1 (mistral-large-2411), Pixtral Large (pixtral-large-2411) and Devstral Medium 1.0 (devstral-medium-2507) on 2026-05-31, replaced by Mistral Medium 3.5; Devstral Small 1.1 (devstral-small-2507) on 2026-05-31, replaced by Mistral Small 4; Voxtral Mini and Voxtral Mini Transcribe (voxtral-mini-2507) on 2026-05-31, replaced by Voxtral Mini Transcribe 2; OCR 2 (mistral-ocr-2505) on 2026-05-31 and OCR 4.0 (mistral-ocr-4-0) on 2026-09-30, replaced by OCR 4.1; Mistral Moderation (mistral-moderation-2411) on 2026-06-30, replaced by Mistral Moderation 2; Mistral Small 3.2 (mistral-small-2506) and Magistral Small 1.2 (magistral-small-2509) on 2026-07-31, replaced by Mistral Small 4; Mistral Nemo 12B (open-mistral-nemo-2407) on 2026-07-31, replaced by Ministral 3 8B; Devstral 2 (devstral-2512) and Magistral Medium 1.2 (magistral-medium-2509) on 2026-07-31, and Mistral Medium 3 and 3.1 (mistral-medium-2505, mistral-medium-2508) on 2026-08-31, replaced by Mistral Medium 3.5. Mistral's table at docs.mistral.ai/models also lists the Labs models it retired. Z.ai GLM 5.2 (zai-glm-5-2) retired on 2026-10-31, replaced by GLM 5.3. Mistral deprecated Mistral Large 3 (mistral-large-2512), Mistral Medium 3.5 (mistral-medium-3-5), Voxtral TTS (voxtral-mini-tts-2603), Voxtral Mini Transcribe 2 (voxtral-mini-2602) and Voxtral Mini Transcribe Realtime (voxtral-mini-transcribe-realtime-2602) on 2026-10-31; all five retire on 2027-04-30, replaced by Mistral Large 4 for the two text models, Voxtral TTS 3 for Voxtral TTS, Voxtral Mini Transcribe 3 for Voxtral Mini Transcribe 2 and Voxtral Mini Transcribe Realtime 3 for Voxtral Mini Transcribe Realtime. Batch processing is half price, and cached input tokens cost up to 90% less. Mistral publishes no rate-limit figures. Each organization's per-model limits (tokens per minute, requests per second) appear in Admin Panel > API > Limits. The tools of Mistral's MCP server are grouped by Studio capability: Skills, Workflows, Connectors, Observability, Evaluations, Organization and Apps.

• Since August 2026, Mistral offers Mistral AI Studio and its API only to business customers. Its consumer terms for personal use exclude both, and API use falls under the Commercial Terms for an organization, company or other entity. (From legal.mistral.ai/terms/row-consumer-terms, read 2026-10-11.)
• A business can use Mistral's API in a commercial product; individuals cannot use the API for personal projects. (From legal.mistral.ai/terms/commercial-terms-of-service, read 2026-10-11.)
• Models whose names start with "labs-" are free of charge once you have API access; Mistral calls them experimental and not for production. (From docs.mistral.ai/inference/model-lifecycle, read 2026-11-12.)
• In Free mode, Mistral may use your Studio inputs and outputs to train its models, and you can opt out at any time. (From help.mistral.ai/en/articles/347617-do-you-use-my-user-data-to-train-your-artificial-intelligence-models, read 2026-11-12.)
• Mistral may train on inputs and outputs from Labs or Preview Models, which its Commercial Terms define as experimental, preview or pre-release models identified as such, including those with the "labs" prefix, even if you opted out or use zero data retention. Mistral Large 4 is a public preview. (From legal.mistral.ai/terms/commercial-terms-of-service, read 2026-10-11.)
• Pay-as-you-go uses prepaid credits. Your monthly usage is consumed first. API and Vibe Code requests beyond it fail with HTTP 402 if your credit balance is zero. Add credits to restore access. Auto Recharge charges your payment method when your balance falls below a set threshold. (From docs.mistral.ai/admin/billing-usage/billing, read 2026-11-04.)

AI model router. Free plan: 50 requests a day, no BYOK. Free models are capped at 20 requests a minute; accounts that have bought at least $10 of credits get 1,000 free-model requests a day. OpenRouter's pricing page says "25+ free models" and "4 free providers"; its model list (openrouter.ai/api/v1/models) had 17 model IDs ending in ":free" on 2026-10-20, and that list changes from week to week. The Standard plan (pay-as-you-go) charges a 5.5% fee on credit purchases and includes BYOK up to $25,000 of list-price inference a month with no fees, 5% after. The Business plan charges an 8% fee on credit purchases. It adds EU and US in-region routing: requests sent to eu.openrouter.ai or us.openrouter.ai stay with providers in that region. Free and Standard do not include in-region routing. No contract or sales call is needed. On 2026-08-19 OpenRouter announced it is joining Stripe. OpenRouter says it will continue to operate as it is, with the same name, product and roadmap, and that existing integrations do not change.

• OpenRouter's free models need no credit card. (From openrouter.ai/blog/tutorials/free-llm-apis-compared, read 2026-10-22.)
• A request over a free-model limit gets a 429 error with the message "Rate limit exceeded". The daily limit counts by UTC day. (From openrouter.ai/docs/api-reference/limits, read 2026-10-29.)
• The paid variant of a model has no platform-level request cap. (From openrouter.ai/docs/api-reference/limits, read 2026-10-29.)
• With a negative credit balance, requests can fail, including for free models; adding credits to bring the balance above zero restores access. (From openrouter.ai/docs/api-reference/limits, read 2026-10-29.)
• OpenRouter does not store your prompts or responses unless you opt in to Private Input & Output Logging or OpenRouter Use of Inputs/Outputs, or content is flagged as potential CSAM. Both opt-ins are off by default. OpenRouter Use of Inputs/Outputs lets OpenRouter use prompt and completion data to improve the product, for a 1% discount on model usage. OpenRouter stores request metadata without prompt or response content. (From openrouter.ai/docs/guides/privacy/data-collection, read 2026-10-30.)
• Each provider has its own data handling policies. OpenRouter works with providers so that prompts are not trained on wherever possible, but there are exceptions. Account settings control routing to providers that may train on your data, separately for paid and free models. If you opt out of training, OpenRouter will not route to those providers. (From openrouter.ai/docs/guides/privacy/provider-logging, read 2026-10-30.)

Workers AI runs AI models on Cloudflare's global network. Every account gets 10,000 Neurons per day at no charge, reset daily at 00:00 UTC; on the Workers Free plan, requests beyond that fail until the reset. On the Workers Paid plan (from $5 per month), usage above 10,000 Neurons per day costs $0.011 per 1,000 Neurons. Eight models require the Workers Paid plan or prepaid AI Gateway credits: @cf/moonshotai/kimi-k2.6, @cf/moonshotai/kimi-k2.7-code, @cf/zai-org/glm-5.2, @cf/zai-org/glm-5.3, @cf/zai-org/glm-5.3-flash, @cf/deepseek-ai/deepseek-v4-flash-0731, @cf/deepseek-ai/deepseek-v4.1-flash-1017 and @cf/deepseek-ai/deepseek-v4-pro-0813. Cloudflare removes 24 models from Workers AI on 2026-11-20, including six of those eight (all but glm-5.3 and deepseek-v4.1-flash-1017); they can be called until then, and from 2026-11-20 requests to them fail with HTTP 410 Gone (error 5028). On 2026-05-30, Cloudflare deprecated 18 models and told users to remove references to them: @cf/meta/llama-3.1-8b-instruct, @cf/meta/llama-3.1-8b-instruct-awq, @cf/meta/llama-3.1-70b-instruct, @cf/meta/llama-3-8b-instruct, @cf/meta/llama-3-8b-instruct-awq, @hf/meta-llama/meta-llama-3-8b-instruct, @cf/meta/llama-2-7b-chat-int8, @cf/meta/llama-2-7b-chat-fp16, @cf/mistral/mistral-7b-instruct-v0.1, @hf/mistral/mistral-7b-instruct-v0.2, @hf/google/gemma-7b-it, @cf/google/gemma-3-12b-it, @hf/nousresearch/hermes-2-pro-mistral-7b, @cf/microsoft/phi-2, @cf/defog/sqlcoder-7b-2, @cf/unum/uform-gen2-qwen-500m, @cf/facebook/bart-large-cnn and @cf/moonshotai/kimi-k2.5. On 2026-10-15, Cloudflare's model catalog still listed @cf/meta/llama-3.1-8b-instruct-fp8, @cf/meta/llama-3.3-70b-instruct-fp8-fast and the -lora variants, but no longer listed @cf/meta/llama-3.1-8b-instruct-fast; llama-3.1-8b-instruct-fp8 and the -lora variants are among the 24 models removed on 2026-11-20. Cloudflare's suggested replacements were @cf/zai-org/glm-4.7-flash, @cf/google/gemma-4-26b-a4b-it and @cf/moonshotai/kimi-k2.6, which is itself removed on 2026-11-20. Since 2026-05-30, requests to @cf/moonshotai/kimi-k2.5 go to @cf/moonshotai/kimi-k2.6, which costs more and requires the Workers Paid plan or prepaid AI Gateway credits; without them, requests get HTTP 403 (error 5035).

Ultra-fast LLM inference API — no permanent free tier. New accounts get $5 in free credits after adding a verified payment method, expiring 30 days after they are granted. Free Trial limits on gpt-oss-120b and qwen-3.8-27b: 5 requests/min and 1M tokens/day. Pay as you go after: GPT OSS 120B $0.35/$0.75 per M tokens, Qwen 3.8 27B $0.99/$1.49 per M tokens. Cerebras's public API now serves only gpt-oss-120b and qwen-3.8-27b, and a request to a model ID it has deprecated fails with 404 model not found. Model IDs Cerebras deprecated in 2026: zai-glm-4.6 on 2026-01-20; llama-3.3-70b on 2026-02-16, replaced by gpt-oss-120b; qwen-3-32b on 2026-02-16, replaced by gpt-oss-120b; llama3.1-8b on 2026-05-27, replaced by gpt-oss-120b; qwen-3-235b-a22b-instruct-2507 on 2026-05-27, replaced by gpt-oss-120b; zai-glm-4.7 on 2026-08-17, with no replacement named; gemma-4-31b on 2026-09-03, replaced by qwen-3.8-27b (Gemma 4 31B stays available on Dedicated Inference).

AI API platform. One model is priced Free in OpenAI's own table: the moderation model omni-moderation-latest. No GPT model is priced free. GPT prices per 1M tokens (Standard, short context): gpt-6-astra $10.00/$50.00; gpt-6.1-sol $2.00/$10.00; gpt-6.1-terra $1.00/$5.00; gpt-6-sol $2.00/$10.00; gpt-6-luna $0.10/$0.50; gpt-5.6-sol $4.00/$20.00; gpt-5.6-terra $2.00/$12.00; gpt-5.6-luna $0.20/$1.20. OpenAI's promotional pricing for gpt-5.6-sol is available until November 30, 2026. Batch and Flex processing halve these prices. gpt-6-astra cached input $1.00 per 1M tokens, against $10.00 uncached. gpt-6.1-sol cached input $0.10 per 1M tokens, against $2.00 uncached. gpt-6.1-terra cached input $0.05 per 1M tokens, against $1.00 uncached. gpt-6-luna cached input $0.01 per 1M tokens, against $0.10 uncached. Prompt caching is on by default. Cache writes cost 1.25× the input price for 30 minutes or 2.5× for 12 hours. Embeddings from $0.02 per 1M tokens. Three further free amounts are sub-quotas inside paid tools: 1 GB of File search storage (then $0.10/GB per day), 1 GB per account per month of ChatKit upload storage, and search content tokens from the web search preview tool on non-reasoning models. Since 2026-10-28, OpenAI's API docs say: "Eligible ChatGPT Pro and Business subscriptions can claim free API credits as part of their subscription benefits." Pro's $100, $200 and $500 tiers get $100, $200 and $500 in API credits a month. Business gets $20 per paid Standard seat and $100 per paid Premium seat, pooled and capped at $500 per workspace a month.

• OpenAI's API credits for ChatGPT subscribers need an active, paid ChatGPT Pro or Business subscription at least seven days old. The owner of the subscription or Business workspace links it to one API organization they own, using the same email. ChatGPT Plus, Go, Free and Enterprise plans, free trials and complimentary subscriptions are not eligible. No API payment method is needed while the credits last. Unused credits expire at the end of the billing cycle and do not roll over. They do not cover Codex used with an API key.

ML model hosting and inference. A new account can run the models in Replicate's Try for Free collection without buying credit, for a limited number of runs that Replicate does not state; after that you add billing and buy credit. Replicate says these models are not free forever. Most models bill by the second for the hardware they run on, such as $0.000025/sec on CPU Small and $0.001525/sec on one H100. Official models bill per output instead, such as FLUX 1.1 Pro at $0.04 per image; per million input/output tokens: DeepSeek-R1 $3.75/$10.

• Replicate does not require a payment method at first for select models, but asks to set up billing after a short time. (From replicate.com/docs/topics/billing, read 2026-10-22.)

ML model deployment platform. New workspaces receive credits for testing and deployment; Baseten does not state the amount. Basic plan: $0 per month, pay as you go. Dedicated deployments bill per minute. Model APIs bill per 1M tokens: GLM-5.3 $1.40/$4.40. GLM-5.3-Flash $0.15/$0.50.When we read the page we cite for this offer on 2026-09-10, we found a change we could not reconcile with the terms we publish, and we have read it again since, on 2026-10-29, without confirming them, so we cannot confirm these terms today.

Grok API, pay as you go: sign up at console.x.ai, then load it with credits. grok-4.7 $2.00/$6.00 (per 1M tokens, under 200k prompt tokens). grok-4.3 $1.25/$2.50 (under 200k prompt tokens). grok-build-0.1 $1.00/$2.00 (under 200k prompt tokens). grok-4.6 and grok-4.5 cost the same as grok-4.7 ($2.00 input and $6.00 output per 1M tokens under 200k prompt tokens), and grok-4.20 (0309 reasoning, non-reasoning and multi-agent) the same as grok-4.3 ($1.25 input and $2.50 output). A request whose prompt reaches 200k tokens is billed at the long-context rate for all its tokens, twice the standard rate: grok-4.7 and grok-4.6 go from $2.00 input and $6.00 output per 1M tokens to $4.00 and $12.00; grok-4.3 and grok-4.20 from $1.25 and $2.50 to $2.50 and $5.00; grok-build-0.1 from $1.00 and $2.00 to $2.00 and $4.00. Cached input costs $0.50 on grok-4.7 and grok-4.6, $0.30 on grok-4.5, and $0.20 on grok-4.3, grok-4.20 and grok-build-0.1. These cached rates also double from 200k prompt tokens. Context windows: 500k tokens for grok-4.7, grok-4.6 and grok-4.5; 1M for grok-4.3 and grok-4.20; 256k for grok-build-0.1. The US endpoint costs 10% more than the global endpoint. Priority Processing (service_tier "priority" on Chat Completions and the Responses API) bills text requests at 2x standard rates. A request xAI's system finds in violation of its usage guidelines is still charged for its generation; one caught before generation in the Responses API costs a $0.05 violation fee. On 2026-05-15 xAI retired eight model names, which still resolve, so code that calls them keeps working: requests to Grok 4.1 Fast (grok-4-1-fast-reasoning, grok-4-1-fast-non-reasoning), Grok 4 Fast (grok-4-fast-reasoning, grok-4-fast-non-reasoning), grok-4-0709 and grok-3 are served by grok-4.3 (low reasoning effort for the reasoning names and grok-4-0709, none for the non-reasoning names and grok-3) and billed at grok-4.3 rates; grok-code-fast-1 is served by grok-build-0.1; grok-imagine-image-pro is served by grok-imagine-image-2.0 at low quality. grok-voice-transcribe-1.0 reached end of life on 2026-10-02; its requests are served by grok-voice-transcribe-2.0 at the same price. Image generation: grok-imagine-image $0.02 per image; grok-imagine-image-2.0 $0.04 per image at 1K resolution and low quality, up to $0.08 per image at 2K resolution and medium quality; $0.01 per input image when editing. grok-imagine-image-quality was retired on 2026-11-02, and its requests are served by grok-imagine-image-2.0 at low quality. Voice API: speech-to-text costs $0.10 per hour of audio (REST) or $0.20 per hour (streaming), text-to-speech $15.00 per 1M characters, and speech-to-speech with grok-voice-3.0 $0.08 a minute ($4.80 an hour). grok-voice-3.0 replaced grok-voice-2.0 on 2026-10-14 at the same price; grok-voice-2.0 is deprecated, and the grok-voice-latest alias now points to grok-voice-3.0. Video generation: grok-imagine-video-1.5 $0.08 per second at 480p, $0.14 at 720p, $0.25 at 1080p. grok-imagine-video-1.5-lite $0.02 per second at 480p, $0.03 at 720p, $0.14 at 1080p. grok-imagine-video $0.05 per second at 480p, $0.07 at 720p. Batch API discounts: 20% off input, cached input, output and reasoning tokens on grok-4.7, grok-4.6, grok-4.5, grok-4.3, grok-4.20-0309-reasoning, grok-4.20-0309-non-reasoning and grok-4.20-multi-agent-0309. grok-4.7 under 200k prompt tokens: $1.60 input, $0.40 cached input, $4.80 output per 1M tokens. grok-build-0.1 does not support Batch API. Image and video generation in Batch API are at standard rates. Server-side tools cost extra, per call, on top of tokens: web_search, code_execution and attachment_search $5 per 1,000 calls, collections_search $2.50 per 1,000, and x_search $5 per 1,000 posts and $10 per 1,000 profiles it returns. view_image, view_x_video and remote MCP tools are billed for their tokens only.

• xAI's API FAQ says it never trains on API inputs or outputs without your explicit permission. (From docs.x.ai/developers/faq/security, read 2026-10-04.)
• xAI stores API requests and responses for 30 days to audit for abuse, then deletes them; teams can turn on Zero Data Retention. (From docs.x.ai/developers/faq/security, read 2026-10-04.)
• Grok Build is xAI's coding agent for the terminal and is not the grok-build-0.1 API model. It can be used without a paid plan, with limited usage, on The X Subscription's $0 plan. Paid plans, Plus $8 to Ultra $200 a month, include it. (From x.ai/pricing, read 2026-10-29.)
• The X Subscription's $0 plan does not include Grok API access. Paid plans include it, but API usage is billed separately at the standard rates and does not draw from the plan's usage pool. (From x.ai/pricing, read 2026-10-21.)
• Grok 4.7 Fast is grok-4.7 on faster infrastructure. It is available only in Cursor and Grok Build, billed through the plan there, and not on the public xAI API; Grok Build on the $0 plan does not include it. Its rates are 2x standard: $4.00 input, $1.00 cached input, $12.00 output per 1M tokens below 200k prompt tokens. (From docs.x.ai/developers/pricing, read 2026-10-21.)
• With the default $0 invoiced billing limit, xAI rejects API requests once prepaid credits run out. Auto top-up (minimum $5) or a higher invoiced billing limit keeps requests running. (From docs.x.ai/console/billing, read 2026-10-21.)
• xAI's API needs credits loaded in console.x.ai, which takes a payment method, before the first request. (From docs.x.ai/developers/quickstart, read 2026-10-22.)
• xAI's Grok for Startups programme gives credits to startups with venture backing, a live product and a company email matching their website. The credits pay for Grok, Grok Build, Grok Bot and the Grok API from one balance, and xAI sizes them by funding, revenue and AI spend to about six months of use. xAI applies 20% on approval and the rest after onboarding. (From x.ai/startups, read 2026-10-29.)
• Grok for Startups credits expire six months after they are applied unless the approval says otherwise. One grant is given per company, and usage after the credits run out is billed at standard rates. (From x.ai/legal/startup-program-terms, read 2026-10-29.)
• xAI's docs now call this API the SpaceXSI API. Accounts and API keys are still created at console.x.ai. (From docs.x.ai/developers/quickstart, read 2026-10-22.)

Claude API with usage-based pricing per million tokens (input/output). Claude Fable 5.2 $8/$40. Claude Fable 5.1 $10/$50. Claude Opus 5.5 $4/$20. Claude Sonnet 5.5 $2/$10. Claude Sonnet 5 $2/$10. Claude Haiku 5.5 $0.10/$0.50 (for prompts up to 100,000 tokens; longer prompts cost five times as much). Claude Haiku 4.5 $1/$5. Anthropic released Claude Fable 5.2 and Claude Mythos 5.2 on November 9, 2026. Claude Mythos 5.2 has the same prices as Claude Fable 5.2 and is offered only to organizations verified through Anthropic's verification programs. The Batch API gives a 50% discount on input and output tokens. Claude Fable 5.2 and Claude Mythos 5.2 fast mode cost $16 per million input tokens and $80 per million output tokens. Claude Opus 5.5 fast mode costs $8 per million input tokens and $40 per million output tokens. Fast mode is not available with the Batch API. Claude Fable 5.2, Claude Mythos 5.2 and Claude Opus 5.5 cache hits $0.20, Claude Sonnet 5.5 cache hits $0.10, Claude Fable 5.1 and Claude Mythos 5.1 cache hits $0.25. Other models’ cache hits cost 0.1x the input price. Cache writes cost 1.25x the input price for 5-minute lifetime and 2x for 1-hour lifetime. Anthropic states "Claude Max, Ultra, and Team plans include monthly credits for the Claude API." Max gets $100 a month, Ultra gets $200, and Team gets $20 per Standard seat and $100 per Premium seat, pooled up to $500. Anthropic's pages state no free credit amount for new API users.

• Monthly credits included with Claude Max, Ultra and Team plans do not cover Claude Code or extra usage in Claude apps. They expire at the end of each billing cycle with no rollover.

Google's data science platform with free notebooks, datasets and competitions. Notebooks get a weekly GPU quota of 30 hours, sometimes more depending on demand (one NVIDIA Tesla P100 or two Tesla T4s), and a TPU v3-8 for up to 20 hours per week. Sessions run up to 12 hours on CPU or GPU and 9 hours on TPU, with 20 GB of auto-saved disk in /kaggle/working. A CPU session has 4 CPU cores and 30 GB of RAM. A GPU session, with one P100 or two T4s, has 4 CPU cores and 29 GB of RAM. A TPU v3-8 session has 96 CPU cores and 330 GB of RAM. Free GPUs and TPUs may queue at busy times. Datasets are capped at 200 GB each and 200 GB of private datasets in total. Kaggle's one paid service is hosting a competition. The tools of Kaggle's MCP server include save_notebook (run with GPU or TPU), get_notebook_session_status, download_notebook_output and get_accelerator_quota (read weekly GPU and TPU usage). The Kaggle API also pushes a notebook version without the web editor. (From https://www.kaggle.com/docs/efficient-gpu-usage, read 2026-10-23.)

Computer vision platform for labeling, training and deploying models. On September 18, 2026 Roboflow announced a free tier for its Core plan: 10 credits that refresh every month, private projects and models, and model weight download. More credits can be bought. Credits pay for storage, labeling, training and cloud deployment; running models on your own hardware with Roboflow Inference uses none. Core's data licensing and model training setting is on by default, including for private projects; a workspace can turn it off. Public plan workspaces are moving to the Core free tier.The page we cite for Roboflow states in words that it is free, which confirms the price — the limits stated here come from our own record rather than from that page.

Data labeling and AI data platform. scale.com/pricing now redirects to a form for booking an intro call and states no prices. Self-serve sign-up for labeling and Nucleus dataset management is open at dashboard.scale.com, and Scale's docs describe a billing tab for on-demand customers. Until at least August 25, 2026, the pricing page offered a Self-Serve Data Engine, paid as you go by credit card, with the first 1,000 labeling units free when you label with your own workforce and the first 10,000 images free in data management.

Keyless Classic API: one image model and GPT-OSS 20B text, free, no sign-up, rate-limited per IP. Every other model needs an API key and Pollen, and free Pollen comes only from quests. No credit card is required. On 2026-10-11, the nine setup quests paid 3 Pollen in total, worth about $3 because 1 Pollen is worth about $1. The documented API for text, image, audio and video requires a GitHub sign-in and an API key. On the keyed API, free use draws from Quest Pollen, with no promise of future grants. Paid-only models, such as Claude models, DeepSeek V4 Pro and Gemini 4 Argon, need purchased Pollen. Gemini 3.8 Flash (google/gemini-3.8-flash) is paid-only on Pollinations, so Quest Pollen cannot pay for it. Kimi K3 (moonshotai/kimi-k3) is not paid-only. Kimi K3.1 Pro (moonshotai/kimi-k3.1-pro) was paid-only until 2026-11-09, when Pollinations made it Quest-accessible; Quest Pollen can now pay for it. To run Claude Code on free Quest Pollen, run "polli harness claude-code on", start Claude Code with "claude --settings ~/.pollinations/claude-code.json", and use a model that is not paid-only. Quest Pollen pays for any model that Pollinations' live catalog (enter.pollinations.ai/models) does not mark paid-only. On 2026-10-18, more than 30 text models were not paid-only, among them GPT-6 Sol, GPT-6.1 Sol, GPT-6 Luna, GLM 5.3, Kimi K3, DeepSeek V4 Flash and DeepSeek V4.1 Flash. The command "polli harness claude-code on" connects Claude Code to Pollinations and uses openai/gpt-6-sol unless you specify another model. Pollinations' harness documentation says the command writes "a Claude Code settings file" and: "Claude Code reads the file only when launched with --settings; plain claude keeps your native login and ~/.claude settings." (From https://github.com/pollinations/pollinations/blob/main/CODING_HARNESSES.md, read 2026-10-20.) GPT-6 Sol costs 1.5 Pollen per million input tokens and 7.5 Pollen per million output tokens. For requests over 272,000 prompt tokens, GPT-6 Sol costs 3 Pollen per million input tokens and 11.25 Pollen per million output tokens, and these rates apply to the whole request. GPT-5 Nano costs 0.0375 and 0.30. GPT-OSS 20B costs 0.05 and 0.18. NVIDIA Nemotron 3.5 Lightning costs 0.045 and 0.165. Adding --model <id> to "polli harness claude-code on" picks another model. The documented API is OpenAI-compatible at the base URL https://gen.pollinations.ai/v1, with an API key from https://enter.pollinations.ai/keys. Pollinations' MCP documentation gives this Claude Code command: "claude mcp add --transport http pollinations https://gen.pollinations.ai/mcp/pollinations --header 'Authorization: Bearer YOUR_KEY'". Its tools include generateImage, generateText, generateVideo, generateAudio, listModels and getBalance. "Calls use the same Pollen wallet as the Pollinations API." The "polli harness claude-code on" command runs Claude Code itself on a Pollinations model; the MCP server gives an agent Pollinations tools. Model IDs of some of the models Quest Pollen can pay for: openai/gpt-6-sol, openai/gpt-6.1-sol, openai/gpt-6-luna, z-ai/glm-5.3, moonshotai/kimi-k3, deepseek/deepseek-v4-flash, deepseek/deepseek-v4.1-flash, openai/gpt-5-nano, openai/gpt-oss-20b, nvidia/nemotron-3.5-lightning, moonshotai/kimi-k3.1-pro.

• Pollinations' Classic API needs no sign-up and no key. image.pollinations.ai (one image model; JPEGs up to 768 × 768 with a small Pollinations logo) and text.pollinations.ai (GPT-OSS 20B, with an OpenAI-compatible endpoint at text.pollinations.ai/openai) are free and rate-limited per IP address: one image request at a time, at least 45 seconds apart, and one text request at a time, at least 30 seconds apart. Past the limit they return HTTP 402 with a Retry-After header. Pollinations runs it on a best-effort basis with no uptime guarantee, and says limits and models can change. Every other model needs a key from enter.pollinations.ai. (From github.com/pollinations/pollinations/blob/master/APIDOCS.md, read 2026-11-06.)
• Pollinations' API docs publish no fixed request rate for secret keys, which carry their own model permissions and budgets. A request can get HTTP 429 with a Retry-After header saying how long to wait. (From github.com/pollinations/pollinations/blob/main/APIDOCS.md, read 2026-10-23.)
• Pollinations' Terms of Service state that model licences vary and commercial use depends on each model's licence. The Terms set no separate rules for usage paid with free Quest Pollen. There is no SLA. (From pollinations.ai/terms, read 2026-10-30.)
• Pollinations does not use prompts or outputs to train or fine-tune models without explicit opt-in. Prompts and outputs are processed transiently and not retained beyond what is needed to run the service, except saved configuration and short-lived response caches. A request to a community-hosted model is sent to that provider, whose own terms govern storage and training; Pollinations does not verify those practices. (From pollinations.ai/privacy, read 2026-10-30.)
• Pollinations stores generated images, video, audio, and 3D files at media.pollinations.ai. Retrieval is public with the URL. These files have a 30-day lifecycle from upload or refresh. (From github.com/pollinations/pollinations/blob/main/APIDOCS.md, read 2026-11-03.)
• Pollinations requires browser apps to use a user-authorized sk_ key from Pollinations Pay. Personal sk_ keys must not be in browser code. A pk_ key only identifies the app and returns 401 if sent as a key. (From github.com/pollinations/pollinations/blob/main/APIDOCS.md, read 2026-11-03.)
• Pollinations Pay, also called BYOP, lets users authorize an app to spend Pollen from their own wallet. Users set budget, expiry, models, and permissions. They can edit or revoke issued keys.

GitHub retired GitHub Models on 2026-07-30, so there is no free tier. GitHub's own documentation states "GitHub Models has been retired." The former offer was free access to 100+ models via GitHub Marketplace at 10-15 RPM and 50-150 requests/day.

Free inference endpoints on build.nvidia.com: models marked Free Endpoint, including DeepSeek V4.1 Flash, GLM 5.3 Flash, gpt-oss-20b, Gemma 4 31B and NVIDIA Nemotron 3 Ultra, can be called at no cost. Their model IDs are deepseek-ai/deepseek-v4.1-flash, z-ai/glm-5.3-flash, openai/gpt-oss-20b, google/gemma-4-31b-it and nvidia/nemotron-3-ultra-550b-a55b. Mistral Large 4 (mistralai/mistral-large-4-1t-a52b) is a Free Endpoint on build.nvidia.com as of 2026-10-29. NVIDIA's free embedding models are nvidia/nemotron-3-embed-1b, nvidia/nemotron-3.5-embed-1b and nvidia/nemotron-3.5-embed-8b. The free reranking model is nvidia/nemotron-3.5-rerank-8b. The 3.5 models handle text and document images and were added on 2026-10-20. Up to 40 requests per minute; limits may vary by model, and traffic from other users may cause throttling. NVIDIA's API Trial Terms allow free use for testing and evaluation only, not production. NVIDIA posts an end-of-life date on each hosted model's page on build.nvidia.com; after that date, requests for the model return HTTP 410 Gone. NVIDIA stopped supporting NVIDIA Nemotron 3 Super (nvidia/nemotron-3-super-120b-a12b) after 2026-10-19, and its catalogue no longer lists the model (checked 2026-10-21). Nemotron 3.5 Super VL (nvidia/nemotron-3.5-super-vl-120b-a12b), an early-access model, is a Free Endpoint. NVIDIA retired Kimi K3 (moonshotai/kimi-k3) on 2026-10-15. Other model IDs NVIDIA retired in 2026 include these.

Cloud-hosted Ollama for running open-source LLMs. Between October 26 and 27, 2026, Ollama replaced its Free plan, which included starter usage credits, with a $0 Pay as you go plan. Pay as you go charges per token for every cloud model, has no subscription and 3 concurrent requests. Running models on your own hardware is free. Reflection's Beam (beam:cloud) was free on Ollama's cloud until November 9, 2026, 12:01 AM PST. Since then Ollama charges $0.125 per million input tokens, $0.015 per million cached input tokens and $0.40 per million output tokens for it (ollama.com/library/beam, read November 9, 2026). Beam is an open-weight model with a 1M-token context window. Pro costs $20 a month with $60 of usage credits, Max $100 a month with $300. Team, in early access, costs $500 a month for unlimited users and includes $1,000 of usage credits a month, shared across the team. Per million input and output tokens, glm-5.3 costs $1.40 and $4.40 and deepseek-v4-pro $1.32 and $3.96. Ollama Cloud serves kimi-k2.6 at $0.95 input and $4.00 output per million tokens, kimi-k2.7-code at $0.95 and $4.00, kimi-k3.1-pro at $2.00 and $10.00, and kimi-k3 at $3.00 and $15.00. kimi-k2.6 and kimi-k2.7-code are the cheapest Kimi models, and kimi-k3 is the most expensive. Usage is billed per million tokens at each model's rate, for example gpt-oss:120b at $0.15 input and $0.60 output, and some models, such as deepseek-v4.1-flash, cost half off-peak (outside 12:00 to 18:00 UTC on weekdays, and all weekend). To use cloud models without installing Ollama, send requests to https://ollama.com/api/chat with an API key from ollama.com in an "Authorization: Bearer" header, using the same model names, such as gpt-oss:120b; OpenAI and Anthropic clients also work.

• Ollama allows one account per person. (From ollama.com/pricing, read 2026-10-28.)
• Included usage on Pro, Max and Team resets monthly on the day the subscription started. Unused included usage does not roll over. Pay as you go accounts pay for each request with usage credits. (From ollama.com/pricing, read 2026-10-28.)
• Ollama says cloud prompts and responses are never logged or used for training. (From ollama.com/pricing, read 2026-10-05.)
• Models run mainly in the United States. Requests may be routed to Europe for capacity. (From ollama.com/pricing, read 2026-10-11.)
• Purchased usage credits expire one year after they are added to the account. (From ollama.com/terms, read 2026-10-11.)
• Pay as you go and Pro include 3 concurrent requests, and Max and Team 10. Requests beyond the limit are queued and processed when a slot is available. If the queue is full, requests are rejected. (From ollama.com/pricing, read 2026-10-28.)

LLM inference gateway. With a free token from dash.llm7.io: 1 request a second, 60 a minute, 250 an hour and 100,000 tokens per 24 hours, counting input and output tokens; LLM7 says free quotas may be reduced without notice. Free access covers turbo-tier models not marked usage-only, such as GLM-5.3-Flash and codestral-latest. Other models, including all image and speech-to-text models, need Pro ($12/mo) or a paid balance. LLM7's limits page no longer lists limits for requests without a token. A text request without a token still worked on 2026-10-19.

• LLM7's terms, updated October 15, 2026, say users keep their rights to prompts and outputs and grant LLM7 a licence to process them only to operate, secure, troubleshoot and improve the service. (From github.com/chigwell/llm7.io/blob/main/TERMS.md, read 2026-10-23.)

Pay-as-you-go model inference. siliconflow.cn, run by a Beijing company, lists these models at no charge: the chat models Qwen3-8B, Qwen2.5-7B-Instruct (Free), Qwen3.5-4B, GLM-4-9B-0414, GLM-Z1-9B-0414, DeepSeek-R1-0528-Qwen3-8B (Free) and Xing4.0-29B; the translation model Hunyuan-MT-7B; the OCR models PaddleOCR-VL-1.5 and DeepSeek-OCR; the embedding models bge-m3, bge-large-zh-v1.5 and bge-large-en-v1.5; the reranker bge-reranker-v2-m3; Kolors image generation; and the speech recognition models XingChenAGI/XingChenGSR-V1.0, XingChenAGI/XingChenASR-V3.2-Ultra, XingChenAGI/XingChenASR-Diarize-V3.0, XingChenAGI/XingChenASR-V3.2 and FunAudioLLM/SenseVoiceSmall. Qwen3-ASR-1.7B is paid at ¥0.00022 per second of audio. The Pro versions are paid: Qwen2.5-7B-Instruct (Pro), bge-m3 (Pro) and bge-reranker-v2-m3 (Pro). All other models are paid too, including DeepSeek-V4-Flash, DeepSeek-V4-Pro and GLM-5.3. Using all the free models requires real-name verification, and online personal verification accepts only Chinese-issued documents, such as a resident ID card or a Foreign Permanent Resident ID Card. The international site, siliconflow.com, is run by SiliconFlow Labs Pte. Ltd. under Singapore law, is not offered in mainland China, and gives $1 in free credits to start. Its paid rates per million input/output tokens: gpt-oss-20b $0.04/$0.18; gpt-oss-120b $0.05/$0.45; DeepSeek-V4.1-Flash $0.15/$0.60.When we read the page we cite for this offer on 2026-09-16, we found the page did not mention this offer, which is not evidence it ended, and we have read it again since, on 2026-11-02, without confirming the terms above, so we cannot confirm these terms today.

• SiliconFlow's international docs say free models have fixed rate limits, paid models' limits depend on the account's usage tier, and new users start at tier L0, which allows 1,000 requests and 40,000 tokens a minute. (From docs.siliconflow.com/en/userguide/rate-limits/rate-limit-and-upgradation, read 2026-10-23.)

China-based GLM model API. The price list marks these models free: GLM-4.7-Flash, GLM-4-Flash-250414 and GLM-Z1-Flash (text); GLM-4.6V-Flash, GLM-4V-Flash and GLM-4.1V-Thinking-Flash (vision); CogView-3-Flash (image); CogVideoX-Flash (video). API calls are rate limited, with a separate concurrency limit per model.The page we cite for this offer does not name it when we last looked, on 2026-10-30, so we cannot confirm these terms today.

Pay-as-you-go LLM API with no free tier, billed from a prepaid balance. DeepSeek-V4.1-Flash (deepseek-flash): $0.30/M input, $1.20/M output at peak. DeepSeek-V4-Pro (deepseek-v4-pro): $1.32/M input, $3.96/M output at peak. Cache-hit input is $0.006/M on Flash and $0.044/M on Pro. Off-peak rates are half; peak hours are 01:00-04:00 and 06:00-10:00 UTC on weekdays. 1M context, up to 384K output. China-based. To call the API today, use deepseek-flash or deepseek-v4-pro: DeepSeek retired the older model names deepseek-chat and deepseek-reasoner on 2026-07-24 (its change log of 2026-04-24 says they "will be discontinued in three months (2026-07-24)"). Until then both ran on the Flash model, deepseek-chat in non-thinking mode and deepseek-reasoner in thinking mode, so deepseek-flash replaces either.

• Since November 1, 2026, 00:00 Beijing time (16:00 UTC on October 31), server-side Search and Fetch calls via DeepSeek Harness, Claude Code, or Codex are billed at $0.75 per 1,000 successful requests; they were free until then. (From api-docs.deepseek.com/quick_start/pricing, read 2026-11-01.)
• DeepSeek's Search API and Fetch API are standalone APIs billed per request. Search finds web pages for a query; Fetch retrieves one web page as Markdown. Each costs $0.75 per 1,000 successful requests. Failed requests, empty search results, and timeouts are not billed. (From api-docs.deepseek.com/guides/search, read 2026-10-17.)
• DeepSeek's Terms of Use, which also govern its API, let DeepSeek use inputs and outputs, de-identified and "to a minimal extent", to develop or improve its services and the technologies behind them. The terms say a user opts out by turning off "Improve the model for everyone". (From cdn.deepseek.com/policies/en-US/deepseek-terms-of-use.html, read 2026-10-23.)
• DeepSeek's privacy policy says it collects, processes and stores personal data in the People's Republic of China. (From cdn.deepseek.com/policies/en-US/deepseek-privacy-policy.html, read 2026-10-23.)

MiniMax sells API access pay-as-you-go on platform.minimax.io. Its pricing pages list no free API allowance; one docs page mentions a free quota for new pay-as-you-go users but gives no amount. Text: MiniMax-M3.1-Flash $0.15/$0.60 (per 1M tokens; cached input $0.015), on pay-as-you-go since its release on 2026-10-19 and the cheapest text model there; MiniMax-M3 $0.30/$1.20 (per 1M tokens, inputs up to 512k, after a permanent 50% discount); MiniMax-M2.7 $0.30/$1.20 (per 1M tokens); MiniMax-M2.7-highspeed $0.60/$2.40 (per 1M tokens). MiniMax M2.5 and M2.7 models are unavailable to new users from 2026-10-19. They are retired on 2026-11-18, after which API requests will not work. For M Plan and Token Plan users, requests to these models are routed to M3.1 Flash from 2026-10-19. Speech: speech-2.8-turbo $60 and speech-2.8-hd $100 per 1M characters. Video: MiniMax-H3 $0.08 per second at 768P. Image: image-01 $0.0035 per image. Music and lyrics APIs closed to new users on 2026-08-20.

The Token Plan no longer takes new purchases.

Web search API for AI agents with Search, Contents, Answer, Monitors and Agent endpoints. The free tier gives $10 in credits each month, up to 2,500 Lite searches, resetting on the first of the month without rollover, plus a one-time $10 onboarding bonus; no credit card or other payment method required. Only a user's first team gets the free credits. Free teams get 10 QPS on search. Search costs $4 per 1,000 requests with up to 10 results for Lite, $7 for Auto, and $12 for Deep. Contents costs $1 per 1,000 pages per content type. Since October 19, 2026, Instant, Fast and Deep Reasoning are legacy search types that keep working at their current prices. Exa recommends Lite in place of Instant and Fast. Search and Contents can also be paid per request over x402 in USDC on Base or Solana, with no API key.

• When a team's credits run out, requests return 402 Payment Required. Auto recharge is optional. (From exa.ai/docs/admin/billing, read 2026-10-06.)
• Exa uses anonymized data on default plans to improve its models. Zero Data Retention is available only on Enterprise plans. (From trust.exa.ai/faq, read 2026-10-06.)

GPU-Bridge's API does not answer, so there is no service to use. Checked 2026-10-07, every path we tried on api.gpubridge.io, the API host its site links to (/run, /catalog, /account/register, /health and /v1/models), returned HTTP 502. Its site, gpubridge.io, still advertises 30 AI services paid per request with x402 USDC on Base or with prepaid credits.

Vertex AI Agent Builder with sessions and memory now GA. Build, deploy, and manage AI agents with persistent memory, multi-turn sessions, and tool governance. Part of the Vertex AI platform.Its pricing page has not resolved for us since 2026-04-15, so we cannot confirm these terms today.

Google Vector Search 2.0 is now Agent Retrieval. It is part of the Gemini Enterprise Agent Platform, formerly Vertex AI Platform. It does approximate nearest neighbor search for AI applications. Pricing is pay-as-you-go. A minimal setup costs under $100 per month.

Free of charge text, image, audio, and video input on the Gemini API free tier, with Google using the content to improve its products. Batch is not available on the free tier. Paid rates are $0.20 per 1M text tokens, $0.45 per 1M image tokens, $6.50 per 1M audio tokens, and $12.00 per 1M video tokens. Batch paid rates are $0.10 per 1M text tokens, $0.225 per 1M image tokens, $3.25 per 1M audio tokens, and $6.00 per 1M video tokens. The same paid rates apply on Google's Gemini Enterprise Agent Platform (formerly Vertex AI). It embeds text, images, video, audio, and PDFs into one embedding space.

Open-source AI coding agent for the terminal, editors, desktop, browser and chat, formerly with a free Qwen OAuth tier. No free tier: Qwen Code's documentation says "The Qwen OAuth free tier was discontinued on 2026-04-15" and points users to Alibaba Cloud Coding Plan, OpenRouter, Fireworks AI or another provider. Coding Plan Pro is $50 a month; a Model Studio API key is billed pay-as-you-go.The page we cite for this offer states no amount, tier or rate we can read when we last looked, on 2026-10-22, so we cannot confirm these terms today.

Cloud sandboxes for AI agents: isolated Linux machines that run generated code and shell commands, work with files and reach the internet. The Hobby plan has no monthly fee and a one-time $100 usage credit, with no credit card needed to start. When the credit runs out, the account is blocked until a payment method is added. Hobby allows 20 concurrent sandboxes and up to 1 hour of continuous runtime per sandbox. Running sandboxes are billed per second for CPU and RAM. Pro is $150/month plus usage.

Inference API for open-source models, billed per token. Together AI does not currently offer free trials; access requires a minimum $15 credit purchase for an organization's first purchase ($5 for later purchases), and the platform is fully prepaid. gpt-oss-120B $0.15/$0.60 (per 1M tokens). Together deprecated Llama 3.3 70B (meta-llama/Llama-3.3-70B-Instruct-Turbo) and removed it from serverless inference on 2026-10-22; Together's deprecations page (docs.together.ai/docs/deprecations) recommends meta-models/Muse-Glimmer-30B ($0.35/$1.50) or a dedicated endpoint instead. Together also removed deepseek-ai/DeepSeek-V4-Flash-0731 from serverless on 2026-10-22; its recommended replacement, deepseek-ai/DeepSeek-V4.1-Flash, costs $0.30/$1.20. DeepSeek V4 Pro is served today as deepseek-ai/DeepSeek-V4-Pro-0813 ($1.32/$3.96); the earlier ID deepseek-ai/DeepSeek-V4-Pro was removed on 2026-08-27. Together AI serverless serves Kimi K3 (moonshotai/Kimi-K3) at $3.00/$15.00 and Kimi K3.1 Pro (moonshotai/Kimi-K3.1-Pro) at $2.00/$10.00; moonshotai/Kimi-K2.7-Code was removed on 2026-08-27, moonshotai/Kimi-K2.6 on 2026-08-19 and moonshotai/Kimi-K2.5 on 2026-05-21. Together removed MiniMaxAI/MiniMax-M3 and thinkingmachines/Inkling from serverless inference on 2026-11-06; its deprecations page recommends MiniMaxAI/MiniMax-M3.1-Flash ($0.15/$0.60) and meta-models/Muse-Spark-Open-816B-A42B ($1.25/$4.25). It removed Qwen/Qwen3.8-2.4T-A95B on 2026-11-04 and recommends Qwen/Qwen3.7-Max ($2.50/$7.50); the old model is not offered on dedicated endpoints. Together also removed these models from serverless inference in 2026, so requests for them fail: openai/gpt-oss-20b on 2026-09-15 (Together recommends Qwen/Qwen3.5-9B); google/gemma-4-31B-it on 2026-09-15 (recommended: zai-org/GLM-5.3-Flash); zai-org/GLM-5.1 on 2026-07-10; Qwen/Qwen3-Coder-480B-A35B-Instruct-FP8 on 2026-06-04; deepseek-ai/DeepSeek-R1 on 2026-05-14; deepseek-ai/DeepSeek-V3.1 on 2026-05-14; meta-llama/Llama-4-Maverick-17B-128E-Instruct-FP8 on 2026-03-31; meta-llama/Meta-Llama-3.1-8B-Instruct-Turbo on 2026-03-06; meta-llama/Meta-Llama-3.1-70B-Instruct-Turbo on 2026-02-25; meta-llama/Meta-Llama-3.1-405B-Instruct-Turbo on 2026-02-06; meta-llama/Llama-4-Scout-17B-16E-Instruct on 2026-02-06. Together's deprecations page says a model can still appear in catalog listings during a transition, and that the runtime API and that page are the source of truth.

• By default, Together stores prompts and responses and may use them for product improvements. Organization admins can turn storage off in privacy settings, enabling zero data retention. (From docs.together.ai/docs/privacy-and-security, read 2026-10-06.)
• Together does not train on your data unless you opt in; the setting is off by default. (From docs.together.ai/docs/zero-data-retention, read 2026-10-06.)

Inference platform for open models, with serverless per-token pricing and on-demand GPU deployments billed per GPU second. Fireworks offers $1 in free credits to get started. Accounts with no payment method, or with no credits, are limited to 10 requests per minute, and an account without a payment method is suspended when the $1 credit runs out until one is added. Serverless prices: OpenAI GPT OSS 120B $0.15/$0.60 (per 1M tokens); MiniMax M3 $0.30/$1.20 (per 1M tokens); GLM 5.3 $1.40/$4.40 (per 1M tokens); Kimi K3 $3.00/$15.00 (per 1M tokens); Kimi K3.1 Pro $2.00/$10.00 (per 1M tokens). Batch inference costs 50% of serverless prices. Image generation and audio inference were deprecated on June 10, 2026. Fireworks removed these models from serverless in 2026, so serverless requests for them fail (dedicated deployments are unaffected), according to its changelog (docs.fireworks.ai/updates/changelog): DeepSeek V4 Pro (0813) (accounts/fireworks/models/deepseek-v4-pro-0813) on 2026-09-25, replaced by DeepSeek V4.1 Flash $0.30/$1.20 (deepseek-v4p1-flash); DeepSeek V4 Flash (0731) (deepseek-v4-flash-0731) on 2026-09-25, replaced by DeepSeek V4.1 Flash; GLM 5.2 (glm-5p2) on 2026-09-25, replaced by GLM 5.3 (glm-5p3); Kimi K2.6 (kimi-k2p6) on 2026-09-25, replaced by GLM 5.3 or Kimi K3 (kimi-k3); Kimi K2.7 Code (kimi-k2p7-code) on 2026-09-25, replaced by GLM 5.3 or Kimi K3; Muse Glimmer 30B (muse-glimmer-30b) on 2026-09-25, replaced by NVIDIA Nemotron 3.5 Lightning 30B A3B $0.05/$0.20 (nemotron-lightning-3p5-30b-a3b); GPT OSS 20B (gpt-oss-20b) on 2026-08-27, replaced by GPT OSS 120B or Qwen3 8B; MiniMax M2.7 (minimax-m2p7) on 2026-08-27, replaced by MiniMax M3; Kimi K2.5 (kimi-k2p5) on 2026-06-26; Qwen 3.6 Plus (qwen3p6-plus) on 2026-06-26, replaced by Qwen 3.7 Plus; MiniMax M2.5 (minimax-m2p5) on 2026-06-17. Fireworks serverless serves Kimi K3 (kimi-k3) at $3.00/$15.00 and Kimi K3.1 Pro (kimi-k3p1-pro) at $2.00/$10.00.When we last read the page we cite for this offer, on 2026-10-28, we found the same terms as an earlier read we had declined to record, so we cannot confirm these terms today.

Serverless platform for running CPU and GPU workloads. The Starter plan has no monthly fee and includes $30 of compute per month (GPU, CPU and memory), 3 workspace seats, 100 containers and 10 GPU concurrency. Usage beyond the $30 is billed per second: T4 $0.000164 per second; H100 $0.001097 per second. Since 2026-09-01, Shared Endpoints are billed per token from the first request and are not covered by the $30. Since 2026-10-01, network egress beyond 1 TiB a month is billed at $0.04 per GiB. Team is $250 per month with $100 of compute included.

• Modal's billing docs say a payment method must be on file to use Modal. (From modal.com/docs/guide/billing, read 2026-10-23.)
• Modal's terms say Modal will not train any AI model on customer data, or send customer data into large language models, without the customer's prior written consent. (From modal.com/legal/terms, read 2026-10-23.)

Free plan at $0 per month: 10,000 credits per month and 3 Projects in Studio, with Text to Speech, Speech to Text, Sound Effects, Voice Design, Music, Productions and Image. No commercial licence on the free plan — that starts at Starter, $6 per month for 30,000 credits. Unused credits do not roll over on the free plan, and cancelling a paid plan drops the account back to it. elevenlabs.io/pricing, read 2026-09-19.

Developer Platform API is credit-priced at 1 credit = $0.01, with 25 free credits to start — a one-time $0.25 grant, not a monthly allowance. Per-image costs: SDXL 1.0 from 0.9 credits, Stable Diffusion 3.5 Flash 2.5, Stable Image Core 3, Stable Diffusion 3.5 Medium 3.5, Large 6.5, Stable Image Ultra 8. Stable Audio 2.5 and 3.0 are 8 credits each. docs.stability.ai/pricing, read 2026-11-06.

Sandboxes for running AI-generated code, priced pay as you go. New accounts get $200 in free compute on a free trial that needs no credit card; Daytona does not say whether the credit expires or renews, and it does not cover GPU sandboxes. A sandbox can use up to 4 vCPUs, 8 GB of RAM and 10 GB of disk, and on the first two usage tiers its network access is restricted. After the credit: $0.0504 an hour per vCPU and $0.0162 an hour per GiB of memory; the first 5 GiB of storage is free.

Sandboxes and runtime for AI agents, priced on usage with no plan fee. New accounts get up to $200 in free credits; Blaxel does not say whether they renew, and its terms say unused service credits expire one year after they are issued unless otherwise specified. The free quota tier allows 10 sandboxes, which it deletes after at most 7 days, and free accounts cannot request higher quotas. A running sandbox costs $0.0000115 per GB of RAM per second; idle time is not billed as active CPU.

Sandboxes for AI agents from Novita AI, billed per second for CPU and RAM while a sandbox runs. New users who complete an account setup survey get $100 in promotional credits for Novita Sandbox usage, with no credit card; the credits expire, and Novita does not state after how long. The free tier allows 5 concurrent sandboxes of up to 2 vCPUs and 4 GB of RAM, each running for at most 1 hour. Paid usage costs $0.0000098 per vCPU-second and $0.0000032 per GiB-second.

Devboxes: secure micro-VM environments for building and running AI agents. New accounts get $50 in usage credits with Pro features and no credit card; usage draws the credit down until it is gone, and nothing is charged automatically when it ends. On the trial: 3 running devboxes, sizes up to Medium (2 CPUs, 4 GB), and at most 1 hour of keep-alive. After the credit, the Basic plan is a free subscription with usage billed at $0.108 per CPU-hour and $0.0252 per GB-hour of memory. Pro is $250 a month plus usage.

Memory layer for AI agents and apps. Free plan: unlimited end users and community support. For the first 30 days Mem0 pays for the model calls, with 10,000 adds and 1,000 retrievals a month. After that, adding memories needs your own LLM key (OpenAI, Anthropic, Azure OpenAI or OpenRouter), billed by your provider; Mem0 puts its recommended models at about $3.55 to $5.34 per 1,000 adds. With a key, Free allows 50,000 adds and 10,000 retrievals a month at no charge from Mem0. Without one, stored memories stay and up to 1,000 searches a month still work, but new adds return an error. Calls past a monthly limit return an error until the next month, unless you connect a key and turn on usage-based billing with a monthly cap you set (Mem0 shows the rate when you turn it on). Mem0 Free accounts that signed up before October 26, 2026 have model calls paid by Mem0 until November 25, 2026; after that, adding memories requires their own LLM key. Starter ($19/month), Growth and Pro are no longer sold to new accounts; existing subscribers keep their plans. Graph memory, user profiles, SSO and on-prem deployment are on the Custom plan, priced by Mem0's sales team. Under Mem0's terms (2026-08-03), Free Plan users grant Mem0 a perpetual licence to their content, including to train AI models; paid plans exclude that, apart from aggregated, de-identified data. Mem0 Open-Source (Apache 2.0) can be self-hosted.

Context and memory layer for AI agents: Zep gives an agent context from past conversations, user activity and changing preferences. The Free plan includes 10,000 credits a month, with no rollover or auto top-up. An Episode (a chat message, JSON payload or block of text) up to 350 bytes costs 1 credit; retrieval, storage and users cost none. Free allows 2 projects, 1 Memory MCP Server seat and 5 custom entity and edge types, with variable rate limits and lower-priority processing. When the credits run out, Episodes stop processing until the next billing cycle and the account's rate limit drops to 5 requests a minute. Flex, the first paid plan, is $125/month for 50,000 credits. The self-hosted Community Edition is deprecated; Graphiti, the framework under Zep, is open source (Apache 2.0).

• Zep's terms (last updated 2026-08-17) give Zep a perpetual, irrevocable licence to use customer data on every plan, Free included, to train and improve AI models; the terms name no opt-out. (From getzep.com/legal/terms, read 2026-10-12.)
• The terms' data-security commitments, including safeguards for customer data and notice of a security incident, cover Paid plans only, not Free. (From getzep.com/legal/terms, read 2026-10-12.)

Stateful AI agents that keep their memory across sessions. The Free plan is $0/month for the Letta app, CLI and web app: up to 3 stateful agents, 5 MiB of storage per memory repository, limited use of Letta Auto, a limited number of LLM requests on rotating free models, and your own model API keys or coding plans. Free is a Personal Plan; API-key access to the Letta API is sold as a Developer Plan, the API Plan at $20/month plus $0.10 per active agent a month and pay-as-you-go model usage. Pro is $20/month for up to 20 stateful agents. The Letta agent harness is open source (Apache 2.0) and runs on your own infrastructure with no Letta account.When we last read the page we cite for this offer, on 2026-11-13, we refused the change we considered recording because it named no figure that had moved, and refusing a change is not a confirmation of the terms above, so we cannot confirm these terms today.

Memory and search API for AI agents, with user profiles and plugins for coding agents. The Free plan is $0/month with $5 of credits included, renewed every month; plan credits do not roll over. Credits pay the same rates on every plan, such as $5 per 1M SM tokens of plain-text memory and $5 per 1M search queries, and usage needs an available credit balance. Free includes the memory and search API and the coding-agent plugins for 1 team seat and unlimited end users; connectors such as Google Drive and Notion need a paid plan. Pro is $19/month with $20 of credits included.

Open-source memory engine that turns documents and data into a knowledge graph agents can query. Cognee Cloud's Free plan is $0/month, labelled "Free forever", with no card required: 1 workspace, unlimited users and API calls, and 1M tokens included (Cognee's billing docs say 10M). Cognee does not say the tokens renew; when the balance runs out, uploads, graph processing and search are refused. Tokens beyond it cost $1.00 per 1M on every plan, and Standard adds workspaces at $5 a month each. The open-source engine (Apache 2.0) is free to self-host.

Google Search API returning real-time results. 2,500 free queries when you sign up, no credit card required; a plain search uses one credit, and Maps and Lens searches use 3. No Serper page says the free queries renew or expire, and the terms bar registering more than one account. Serper stops accepting queries when the balance reaches zero. Paid credits are prepaid packs with no subscription: Starter is $50 for 50,000 queries ($1.00 per 1,000) at 50 queries per second, valid for 6 months; the largest pack falls to $0.30 per 1,000.

• Serper is a business-to-business service. The Terms of Service do not restrict commercial use. The same Terms apply to free and paid queries. (From serper.dev/terms, read 2026-10-29.)

Web search API for AI agents. Accounts created with a professional email address get $20 of credit, topped back up to $20 each month (Linkup's docs); the pricing page calls this 4,000 free queries and states no period. Linkup's app asks other sign-ups to add a card, with no charge, to unlock the credit. Rate limit: 10 queries a second per organization. Then pay as you go from a prepaid balance: search $0.005 a call ($0.006 with a sourced answer or structured output), deep search $0.05 to $0.055, fetch from $0.001. Top-ups of $1,000 or more earn 10-20% bonus credit.

• Startups can apply for a one-time credit of up to $5,000 by telling Linkup what they are building. (From linkup.so/startups, read 2026-10-12.)
• When the account's credit runs out, the API responds with HTTP 429. (From docs.linkup.so/pages/documentation/platform/pricing, read 2026-10-12.)

Web search and research APIs for AI agents. Organizations with a credit card on file get $5 of free credit each month, and unused credit expires at month end. $5 covers up to 1,000 requests a month in Search's Basic or Advanced mode (Advanced is the API default), or 5,000 in Turbo or Fast mode; usage beyond $5 is billed to the card at standard rates. The $5 monthly credit applies to all Parallel APIs at their standard rates. Extract costs $1 per 1,000 URLs, and the Decisions API costs $1 per 1,000 requests, up to 100 questions per request. One monthly credit per organization and per card; marketplace and postpaid organizations are not eligible. The pricing page also offers "up to $80 at signup" without stating its terms. A hosted Search MCP is free without an account or API key, at lower rate limits, for personal and hobby use. Then pay as you go: Search $1 per 1,000 requests (Turbo, Fast) or $5 (Basic, Advanced) with 10 results, at 600 requests a minute.

Search, Reader, embeddings and reranker APIs. Each new API key comes with 10M free tokens, shared across these APIs; no page says they renew. Jina's FAQ states for the hosted API: "No separate license needed. Commercial use is covered by the service terms: sign up and pay through this site or the cloud marketplace." CC BY-NC 4.0 covers self-hosting the model weights. The exception is jina-embeddings-v4, which is non-commercial only even through the API. Search (s.jina.ai) needs a key and costs at least 10,000 tokens a request, so the free tokens cover at most 1,000 searches. Search allows 100 requests a minute with a free key and the same with a paid key; only a premium key raises it, to 1,000. Reader (r.jina.ai), which converts a URL to LLM-friendly text, allows 500 requests a minute with a free or paid key, 5,000 with a premium key, and 20 without a key. Reader without a key is free and uses no tokens, so it keeps working after a key's free tokens run out. Paid tokens are prepaid: 1 billion for $50 ($0.05 per million), or 11 billion for $500 with a premium key. Jina AI has been part of Elastic since October 2025.The page we cite for Jina AI states in words that it is free, which confirms the price — the limits stated here come from our own record rather than from that page.

• Jina's terms say it does not use customer inputs to train models, but may use aggregated, anonymized operational metadata to improve services. (From jina.ai/legal, read 2026-10-16.)

Web Search API for AI agents. 100 free queries a day with no API key or account through the keyless MCP profile (api.you.com/mcp?profile=free), limited to the you-search and you-discover tools. New API accounts also get a $100 sign-up credit with no credit card required; no page says it renews or expires. Then pay as you go with no minimums: Web Search API $5.00 per 1,000 calls with up to 100 results per call, live page extraction $1.00 per 1,000 pages, at 10 requests a second on self-serve accounts.

Hetzner's experimental Inference API: an OpenAI-compatible API for open-weight models, free while it stays experimental. Base URL: https://inference.hetzner.com/api/v1. Models listed on 2026-10-15, with the IDs Hetzner's docs give: Qwen/Qwen3.6-35B-A3B-FP8 and Qwen3.8-27B, each with a 262,144-token context and image input. Hetzner says the list will change while the API is experimental; GET /v1/models returns the current one. Limits per API key, per minute: 4M input tokens, 100k output tokens and 10 requests. Needs a Hetzner account; keys are created at experiments.hetzner.com. Hetzner says it does not store the content of requests or responses.The page we cite for Hetzner Inference API states in words that it is free, which confirms the price — the limits stated here come from our own record rather than from that page.

• Hetzner says not to use the Inference API for production: it is experimental and offered as is, with no guarantee of performance or availability. (From docs.hetzner.com/general/company-and-policy/experiments/inference, read 2026-10-09.)
• It is free only while it stays experimental. Hetzner says it will email users before that changes. (From docs.hetzner.com/general/company-and-policy/experiments/inference, read 2026-10-09.)

Cloudflare AI Search is a managed search service for indexing content and querying it with natural language from a Workers binding, REST API or MCP server. Every account receives 5 million ingestion tokens, 10 GB-month of storage, 1,000 semantic queries, and 1,000 full-text queries each month. The Workers Free plan includes 100 AI Search instances per account, 100,000 files per instance, and 500 pages crawled per day. Billing begins December 1, 2026, and usage before that date is not charged. Beyond the included usage, base ingestion costs $0.75 per million tokens; storage is $2.00 per GB-month; semantic, vector and hybrid queries are $0.75 per 1,000 queries; full-text queries are $0.10 per 1,000 queries. Embedding and reranking usage is included in AI Search usage, while generation and query rewriting are billed separately through Workers AI or the external model provider that runs them.

Search and research API for AI agents: one credit balance covers Search, Contents and DeepResearch. Accounts without a plan get free credits every month, which reset and do not roll over: 2,000 with a work email, no card needed; 1,000 with a personal or university email, which needs a card on the account from the second month (adding one charges nothing; one card unlocks free credits for one account, and prepaid cards don't count). Free monthly credits cover web search, arXiv and PubMed; other sources need a plan. A web search returning ten results uses 1 credit. Then pay as you go: $10 buys 1,600 credits, which last 12 months; Ridiculously Cheap is $29 a month for 5,000 credits. There are no overage charges: a request the balance cannot cover gets HTTP 402.

• In the first month only, the first 1,000 free credits with a work email (500 with a personal email) also work on every source on Valyu's standard plans, such as filings, trials or patents. Valyu's own pricing page at www.valyu.ai states the 1,000 without the first-month limit or the personal-email figure. (From docs.valyu.ai/pricing, read 2026-11-12.)
• Valyu's free credits were a one-time grant until late 2026: its changelog entry for October 2026 gives new accounts $10 of credits, or $20 with a company email, usable on every standard-plan source. Its pricing page now gives a monthly allowance that resets each month. (From docs.valyu.ai/pricing, read 2026-11-12.)

AI code editor built on VS Code. Since 2026-10-12, Cursor's pricing docs (cursor.com/docs/models-and-pricing) say: "Cursor is sold as part of The X Subscription, one subscription for Grok, Cursor, and X." Free is $0, with limited Agent and Chat usage. Paid plans are Plus $8/month, Premium $30/month (4x Plus's usage), Super $100/month (15x) and Ultra $200/month (50x), or $80, $300, $1,000 and $2,000 a year. Each paid plan's usage is one weekly pool shared with Grok, covering Grok 4.7, Grok 4.6, Grok 4.5 and Cursor's Composer 2.5. Claude, GPT, Gemini and other third-party models are outside every plan's pool: on Premium and above they cost the model's API list price, paid from prepaid credit, and Free and Plus cannot use them or your own API keys. Teams seats are $30, $100 or $200 per user a month, and on Teams and Enterprise third-party models cost API list price plus the Cursor Token Rate. Existing Hobby, Pro ($20), Pro+ ($60), Ultra and Teams Standard and Premium subscribers keep their plans, with monthly usage pools and included third-party usage, until they choose to switch. Cursor announced the change on its forum on 2026-10-12 (forum.cursor.com/t/introducing-the-x-subscription/174450).

• Cursor's data-use page says that with Privacy Mode off it may use and store your codebase data, prompts, editor actions and code snippets to train its models. To keep your code out of training, check that Privacy Mode is on in Cursor's settings; any user can turn it on. (From cursor.com/data-use, read 2026-10-15.)

• Until November 18, 2026, the Free and Google AI Plus plans include Claude Sonnet 4.6, Claude Opus 4.6 and GPT-OSS-120b; Google removes these models on that date. After that date, Antigravity's models page lists two reasoning models for the Free and Google AI Plus plans: Gemini 3.8 Flash and Gemini 4 Hydrogen. (From antigravity.google/docs/models, read 2026-11-13.)
• Google AI Pro and Ultra include Gemini 4 Argon, Claude Sonnet 5.5 and Claude Opus 5.5. On a Google AI Pro trial, Claude Sonnet 5.5 and Claude Opus 5.5 are not included and Gemini 4 Argon is included only on trials with eligible premium devices. (From antigravity.google/docs/models, read 2026-10-28.)
• Since November 10, 2026, Gemini 4 Carbon is in Antigravity on Google AI Ultra and Enterprise only, in the Antigravity app, CLI and IDE extensions. The Free, Google AI Plus and Google AI Pro plans do not include it. (From antigravity.google/blog/gemini-4-carbon-in-google-antigravity, read 2026-11-11.)
• Gemini 4 Hydrogen has been in Antigravity since November 12, 2026. Antigravity's models page lists it on every plan, including Free and Google AI Plus. Google's announcement says it is rolling out across paid Google AI Pro and Ultra subscribers. Orchestrator (Argon) is on paid Google AI Pro and Google AI Ultra, Orchestrator (Carbon) on Google AI Ultra only. Each pairs a planner (Gemini 4 Argon or Gemini 4 Carbon) with Gemini 4 Hydrogen. (From antigravity.google/blog/gemini-4-hydrogen-in-google-antigravity, read 2026-11-13.)
• Google's FAQ says some models "are not included in free trials" and directs memberships through third-party partners, Pixel Pass, or Google Fi to Google One help for subscription management. (From antigravity.google/docs/faq, read 2026-10-23.)
• Google's FAQ calls using third-party software (Claude Code, OpenClaw, and OpenCode) with an Antigravity login a violation of its Terms of Service that can lead to suspension or termination of the account. Google recommends a Gemini Enterprise or Google AI Studio API key for third-party coding agents. (From antigravity.google/docs/faq, read 2026-10-21.)

Open-source terminal AI coding agent by Google, Apache 2.0 licensed. Since 2026-06-18, Login with Google no longer works for personal accounts, according to Google's Gemini Code Assist deprecation notice. The README advertised 60 requests a minute and 1,000 a day with a personal Google account until October 16, 2026, when Google removed it. For unpaid-tier and Google One users, Google says Gemini CLI was replaced by Antigravity CLI on June 18, 2026. Google says Gemini CLI has not been optimized for Gemini 4 Argon and to use Antigravity for Gemini 4 Argon. With a Gemini API key, use counts against the Gemini API's own free tier and pricing. Google stopped selling new Gemini Code Assist Standard and Enterprise subscriptions on 2026-10-09, so a team cannot buy one now to use Gemini CLI. Subscriptions bought before then still work with Gemini CLI. Annual Gemini Code Assist Standard and Enterprise subscriptions can be renewed until 2027-01-31 and monthly ones until 2027-12-31. Google points personal users to its Antigravity products, including Antigravity CLI. Supports MCP tools, shell commands and file editing.The page we cite for this offer states no amount, tier or rate we can read when we last looked, on 2026-10-24, so we cannot confirm these terms today.

• With a Gemini API key, Gemini CLI uses the Gemini API Free Tier, which needs no billing account or credit card. Linking a billing account and prepaying at least $5 moves the project to the Paid Tier. (From ai.google.dev/gemini-api/docs/billing, read 2026-10-23.)
• On the Free Tier, a request over any rate limit gets a rate limit error. Limits apply per project, not per key. Daily request quotas reset at midnight Pacific time. (From ai.google.dev/gemini-api/docs/rate-limits, read 2026-10-23.)
• Google's Gemini API pricing page says Free Tier content is used to improve Google's products, which covers Gemini CLI prompts sent with a free API key. (From ai.google.dev/gemini-api/docs/pricing, read 2026-10-23.)

Coding agent by OpenAI. Available with a ChatGPT subscription, including the $0 Free plan, and separately with an API key billed on token use; both routes are current. OpenAI's Codex pricing page lists Free ($0/month, "Explore Codex capabilities on quick coding tasks") and Go ($8/month, "Use Codex for lightweight coding tasks"), both with GPT-6 Luna at Standard speed in the desktop app, subject to rollout. Plus ($20/month) adds Codex on the web, in the CLI, in the IDE extension and on iOS, cloud code review and Slack integrations, and GPT-6.1 Sol and GPT-6 Luna. Pro plans are Pro 100 ($100/month), Pro 200 ($200/month), and Pro 500 ($500/month). Ultrafast mode is only on Pro 500. Pro plans have no five-hour limit. On 2026-10-29 OpenAI canceled the Pro 200 allowance reduction it had announced on September 29, 2026. Every Pro 200 subscription, new or existing, now has the same Work and Codex allowance at $200 a month. Pro 100 and Pro 500 now include twice their previous Work and Codex allowance. Plus usage is unchanged. ChatGPT Business has two seat types, both carrying Codex: Standard at $20/user/mo billed annually ($25 monthly) and Premium at $100/user/mo billed annually ($125 monthly), where Premium buys 5x more usage than Standard and removes the five-hour usage limit. The Codex pricing page we cite lists only the Standard seat — the Premium seat is published on OpenAI's business pricing page. Codex-only pay-as-you-go seats closed to new Business workspaces on 2026-06-24; existing seats continue. With an API key, Codex runs in the CLI, SDK or IDE extension at API prices, without the cloud features.

• Since 2026-10-28, ChatGPT Pro and Business subscriptions include monthly OpenAI API credits. These credits do not pay for Codex used with an API key. They do not raise ChatGPT or signed-in Codex usage limits. (From developers.openai.com/api/docs/guides/chatgpt-api-credits, read 2026-10-29.)
• On Free, Plus, and Pro, OpenAI may use your content to train its models. This includes Codex tasks. By default, OpenAI does not use inputs or outputs from ChatGPT Business, ChatGPT Enterprise, ChatGPT Edu, or the API to improve its models. (From help.openai.com/en/articles/5722486-how-your-data-is-used-to-improve-model-performance, read 2026-10-30.)
• To opt out, turn off Improve the model for everyone under Settings > Data controls in ChatGPT, or select Do not train on my content in the Privacy Portal. Either option applies to ChatGPT and Codex. Codex has a separate Include environments setting for training on full environments, which those settings do not change. (From help.openai.com/en/articles/5722486-how-your-data-is-used-to-improve-model-performance, read 2026-10-30.)
• OpenAI's Terms of Use for its services for individuals state you retain ownership rights in Input and own the Output. You may not use Output to develop models that compete with OpenAI. No restriction on commercial use is listed. (From openai.com/policies/terms-of-use, read 2026-10-30.)
