Pydantic-AI
Pydantic AI is a Python agent framework designed for building production-grade applications and workflows that leverage generative AI. It offers a model-agnostic interface enabling developers to access multiple large language model providers such as OpenAI, Anthropic, Google Vertex, Groq, and AWS Bedrock. The framework emphasizes type-safe operations and structured response validation by integrating Pydantic's validation system with modern Python features like type hints. It supports durable execution to maintain agent progress through API failures and application restarts, and includes advanced capabilities such as the Model Context Protocol (MCP), agent-to-agent communication, streaming outputs, and human-in-the-loop approval workflows. The core framework is open source under the AGPL-3.0 license, allowing self-hosting and file-based configuration.
Pydantic AI is a Python framework for building type-safe, multi-provider generative AI agents with durable execution and structured validation.
