Lab Overview
This hands-on lab teaches you to build a multi-provider LLM integration service using FastAPI and Python.
You'll learn to:
- Create an abstract LLM client interface for provider-agnostic code
- Implement OpenAI and Ollama providers with a unified interface
- Build automatic failover when the primary provider fails
- Implement streaming responses for better user experience
- Add structured JSON output with Pydantic validation
- Test the complete service with multiple scenarios
This lab builds the foundation for the AI Gateway you'll deploy in the next lab.
