14. How to Integrate Multiple LLMs into One System (OpenAI, Google Gemini, vLLM, Ollama)

How do you build an AI system that isn't locked into a single provider? In this video, we dive into the core implementation of our LLM Ops project to see how to handle multiple LLM backends simultaneously. Whether you want to use a hosted API like OpenAI or Google Gemini, or a local open-source model via Ollama or vLLM, our architecture allows you to swap them instantly via a single configuration change. What we cover in this code walkthrough: 1. Provider Abstraction: A look at the modular classes built for OpenAI, Gemini, vLLM, and Ollama. 2. The "Mock" Provider: Why building a mock class is…
