It includes the AutoGen Studio for no-code GUI setup, integrating with various models; pick pydantic-ai if pydantic AI is a Python framework for developing production-grade applications with Generative AI using the robust validation offered by Pydantic. [autogen](https://microsoft.github.io/autogen/) reports 60k GitHub stars, 9.0k forks, and 945 open issues, last pushed Apr 15, 2026. [pydantic-ai](https://pydantic.dev/pydantic-ai) has 18k stars, 2.3k forks, and 492 open issues, last pushed Jul 11, 2026.
