Pydantic AI Updates: May 13, 2026

1. Pydantic AI 1.95.0 ships native Tool Search and Instrumentation capability

Pydantic AI. v1.95.0 adds native Tool Search support on Anthropic and OpenAI with pluggable custom search strategies on any provider, and introduces an Instrumentation capability that supersedes the Agent(instrument=...) argument (now deprecated). The release also lands structured output combined with tool use for Gemini 3 via the Google provider, plus V2 preparation work: a rename from “built-in tools” to “native tools” registered through capabilities=[NativeTool(...)], and an opt-in local= flag for provider-adaptive capability fallback.

2. Pydantic AI 1.94.0 trims Mistral dependency and refines OpenAI profile flags

Pydantic AI. v1.94.0 drops mistralai as a default dependency of the core pydantic-ai package, leaving Mistral support as an optional install, and adds a new openai_chat_supports_multiple_system_messages profile flag so providers wrapping the OpenAI Chat schema can advertise multi-system-message support without monkey-patching. It is a small release that mostly clears the deck for the larger 1.95.0 cut later the same day. Source
