What happens when you need to switch AI providers? If your application is tightly coupled to a single API, even a simple change can require significant rework. That's why many AI teams use a gateway layer between their application and LLM providers.
In this hands-on project, you'll build a multi-provider LLM gateway from scratch using Python. You'll create a single interface that works across providers like Anthropic and TogetherAI, handle authentication and response differences behind the scenes, and learn the architectural patterns that make AI applications easier to maintain, scale, and extend.
