When do your AI models stop working?

Vendors retire model versions on fixed dates, and calls to them start failing. Here is every retirement OpenAI, Anthropic, Google Gemini, Mistral, and Cohere have announced, and a check that finds the ones your repository still calls.

Every model ID in its code and config is matched against the list below, including Bedrock, Vertex AI, LiteLLM and OpenRouter spellings. You get the retirement date, the vendor's replacement and every file and line that uses it.

Next: veo-3.1-lite-generate-preview (Google Gemini) on Oct 22, 2026. Checked against the vendors' deprecation pages on Oct 11, 2026. Google gives the earliest possible date and announces the exact day later.
