Your agent can't read a deprecation page

Automated excerpt

When a provider retires a model, the notice goes on a docs page written for people. The API keeps answering until the shutdown date, then the model ID just stops working. Mistral marked 5 more model IDs deprecated, with shutdown on Apr 30, 2027, and retired one on Oct 31. 9 model IDs shut down in the next 30 days, including five Gemini TTS and live previews on Nov 17 and claude-sonnet-4-5-20250929 on Nov 30.
