OpenRouter

OpenRouter is an API aggregator that gives you a single endpoint and a single API key to access 200+ language models: Claude, GPT-4o, Gemini, Llama 3, Mistral, Hermes, Phi-3, and dozens more — including a substantial catalogue of genuinely free models (google/gemma-2-9b-it, meta-llama/llama-3.1-8b-instruct, mistralai/mistral-7b-instruct, and others). For n8n workflows in this course, OpenRouter is the recommended LLM backend: add a single HTTP Request node, set the Authorization header once, and switch between any model by changing one parameter. This makes it trivial to compare Claude vs. Llama vs. Gemini on the same task, or to build a router that tries a fast cheap model first and falls back to Claude only when needed. OpenRouter also provides unified token usage tracking across all providers in one dashboard.
