deprecated effective 2026-10-14 medium impact

ChatGPT and Codex keep running. Only the GPT-5.5 model retires from ChatGPT, ChatGPT Work and Codex on all plans on 2026-10-14. For Codex with ChatGPT sign-in, OpenAI names GPT-6.1 Sol as the replacement on Plus, Pro, Business, Enterprise and Edu plans (its page named GPT-6 Sol when we read it on 2026-10-06) and GPT-6 Luna on Free and Go plans.

deprecated effective 2026-06-24 low impact

ChatGPT Business and Codex keep running. From 2026-06-24, new self-serve ChatGPT Business workspaces cannot add Codex-only seats, which OpenAI now calls a legacy seat type. A workspace that added one before that date can keep adding them, and Standard and Premium ChatGPT seats include Codex. Source ↗

new tier effective 2026-04-02 medium impact

OpenAI added Codex-only seats for ChatGPT Business and Enterprise workspaces, with no fixed seat fee, no rate limits and usage billed on token consumption, and cut ChatGPT Business's annual price from $25 to $20 per seat. Standard Business seats, which include Codex with usage limits, continued. Source ↗
