What you'll learn

LLM-powered APIs often become tightly coupled to one provider, making migrations expensive and governance inconsistent. In this course, The Agnostic AI Gateway: Orchestrating LLM Flows in FastAPI, you'll gain the ability to design and implement a vendor-neutral AI gateway architecture. First, you'll explore abstraction-driven provider wrappers and intent-based routing. Next, you'll discover how to normalize provider streaming with SSE and orchestrate parallel operations safely using async task groups. Finally, you'll learn how to add semantic caching with Redis embeddings plus gateway-level guardrails for prompt injection and PII protection. When you're finished with this course, you'll have the skills and knowledge of production-ready AI gateway design needed to evolve model strategy without destabilizing your FastAPI application.
