Performance summary for 2025-11 focusing on pydantic/pydantic-ai OpenAI model integrations. This month delivered a critical reliability improvement by standardizing how the model name is accessed across OpenAI integrations. The change replaces the internal _model_name usage with a consistent model_name property, affecting both the OpenAIChatModel chat completion flow and the underlying OpenAI model implementations (including streaming paths). This unifies API surfaces, reduces edge-case bugs, and improves stability for chat-based workloads that rely on correct model routing. Commits implementing the fix: - 1748efded7b1e89004a68e0437ac85e999f99770 (Use `model_name` property in `OpenAIChatModel` chat completion create request (#3543)) - 5eb777838b9ee025ca0748726b8a1edb075ee9ca (Replace direct `_model_name` access with `model_name` property in OpenAI models and streamed responses (#3564))
