FastAPI for AI Services
FastAPI is the go-to framework for serving AI models in Python. It's fast, has automatic OpenAPI docs, and uses Pydantic for request validation — which catches bad input before it reaches your model.
Pydantic Models
Pydantic models define the shape of your request and response data. They validate input automatically and generate clear error messages when data doesn't match the expected schema.
In production AI services, input validation prevents crashes from malformed data. Always validate before inference.
Key Takeaway
FastAPI + Pydantic gives you type-safe, auto-documented AI endpoints with minimal boilerplate.
