About

PydanticAI is a Python-based agent framework designed to simplify the development of production-grade applications using generative AI. Built by the team behind Pydantic, the framework integrates seamlessly with popular AI models such as OpenAI, Anthropic, Gemini, and others. It offers type-safe design, real-time debugging, and performance monitoring through Pydantic Logfire. PydanticAI also provides structured responses by leveraging Pydantic to validate model outputs, ensuring consistency. The framework includes a dependency injection system to support iterative development and testing, as well as the ability to stream LLM outputs for rapid validation. It is ideal for AI-driven projects that require flexible and efficient agent composition using standard Python best practices. We built PydanticAI with one simple aim: to bring that FastAPI feeling to GenAI app development.

About

a13n is an open-source AI agent development framework and self-hosted platform for building, testing, and running agent applications. Developers define agents with instructions, models, tools, and execution environments using the Python Harness SDK, or configure agents through Harness UI. The Service provides a shared workspace and HTTP API for applications that need managed agents, saved conversations, and resumable runs. Agent work can execute locally or on a deployed Service, with checkpointing for eligible runs. The platform connects to model providers, external applications, web-data services, and remote MCP servers, and can be deployed using Docker Compose or Kubernetes. It is designed for software developers and platform teams creating AI-enabled workflows and applications; customers operate their own infrastructure and provider credentials.
