Whichever new model has you most excited, Pydantic AI has you covered. Claude Opus 5.5 from @AnthropicAI and GPT-6 Sol and Luna from @OpenAI, supported on launch day. And Jev from @typesafeai, not even a week old. Upgrade, then change one string. https://github.com/pydantic/pydantic-ai/releases/tag/v2.48.0?utm_source=x&utm_medium=social&utm_campaign=v2-48-day-one-models
