Hugging Face Inference Providers have been integrated into Pydantic AI, a Python framework for building production-grade AI agents, offering developers access to thousands of open-source LLMs through a single API. This integration allows for the creation of applications like a multi-agent flight booking system, where agents can handle tasks such as flight search and seat selection using structured Pydantic models for data validation. The tutorial demonstrates the simplicity of setting up an AI agent using Pydantic AI and Hugging Face, showcasing a working example of a flight booking system powered by the Together AI inference provider. Users are encouraged to explore the extensive capabilities of Pydantic AI and Hugging Face Inference Providers for developing more complex and production-ready AI applications, with options for subscription to gain additional features and credits.
