Major AI providers are planning to retire several large language models in the coming weeks. Anthropic, Google, and OpenAI have announced deprecation dates for specific versions of their models, including Claude Sonnet 4.5, Gemini 2.5 variants, and GPT-5 models. Users are advised to check the providers' official documentation for exact dates and to update their code and configurations to use the replacement models, as retired models will cease to function or may be rerouted to different, potentially less capable, models with altered billing rates.
