~15 OpenAI models retire on July 23, 2026 — including five Codex models

These aren't obscure snapshots. The batch includes gpt-5-codex and the whole gpt-5.1-codex / gpt-5.2-codex family, the *-chat-latest aliases, computer-use-preview, the GPT-4o search / audio / realtime mini variants, and the deep-research models. If one of them is wired into a coding assistant, an agent, or a background job, it will simply stop working on the shutdown date — usually with no error you'd catch in advance.

The Codex models retiring July 23

Sorted with the coding models first, since that's what most teams will feel. Days left updates live.

Source: OpenAI deprecations. Replacements above are the ones OpenAI lists on that page. Note that OpenAI's current generation is now gpt-5.6 (gpt-5.6-sol / -terra / -luna) — if you're migrating anyway, it's worth testing against that rather than only the like-for-like replacement.

If you use a Codex model, do this before the 23rd

Migrating LLM models is rarely a pure drop-in — output format, tone, and tool-calling behavior can shift, so test before you cut over:

• Coding models (gpt-5-codex, gpt-5.1-codex, gpt-5.1-codex-max, gpt-5.2-codex) → gpt-5.5; gpt-5.1-codex-mini → gpt-5.4-mini.
• *-chat-latest aliases → gpt-5.5.
• Deep-research (o3-deep-research, o4-mini-deep-research) → gpt-5.5-pro.
• Search / computer-use previews → gpt-5.4-mini.
• Audio / realtime / TTS mini → the newer gpt-audio-1.5 / gpt-realtime-mini / dated TTS snapshot.
