Hetzner Inference API free tier includes Hetzner's experimental Inference API: an OpenAI-compatible API for open-weight models, free while… Catalogue date October 2026. Compare with 26 alternatives in AI / ML.
Source states a free price: 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.
Subtypes in AI / ML: llm_api — the vendor runs language or multimodal models on its own infrastructure and sells calls to them by model name; you send a prompt and receive a completion. We read that on 2026-10-09 from https://docs.hetzner.com/general/company-and-policy/experiments/inference/, where it says: “The Inference API provides access to open-source large language models via an OpenAI-compatible REST API.” How we use this.

How Hetzner Inference API compares against every one of the 26 we list, not against a selection of them. A surface with room for every member of a tied set may rotate their order. A surface with room for only some of them names none of them, because which ones it named would be the claim, and a claim seeded on the date is not the one we serve tomorrow. How we decide this.
