A modern, high-performance Python web framework for building APIs, with automatic OpenAPI documentation, data validation using Pydantic, and async support (commonly used to expose model inference endpoints).
Key Features
- Automatic data validation and serialization using Python type hints and Pydantic.
- Automatic OpenAPI/interactive docs (Swagger UI, ReDoc) generation.
- High-performance async support (built on Starlette) for building low-latency APIs.
- Easy to integrate with ML inference code and deployment stacks.
