name: PydanticAI
description: 'PydanticAI is an open-source, model-agnostic Python agent framework built by the Pydantic team, designed to
  bring the ergonomic, type-safe design philosophy of FastAPI to production-grade generative AI application development. It
  provides structured outputs, dependency injection, and first-class support for leading model providers including OpenAI,
  Anthropic, Google Gemini, xAI, AWS Bedrock, Cohere, Mistral, Groq, and many more. The framework integrates seamlessly with
  Pydantic Logfire for OpenTelemetry-based observability, and includes pydantic-graph for complex agentic workflows, pydantic-evals
  for systematic agent evaluation, and clai for a CLI chat interface. PydanticAI is maintained by Pydantic, a London-based
  developer tooling company backed by Sequoia Capital, and forms a core part of their end-to-end AI engineering stack.
