OpenRouter

OpenRouter acts as a bridge between your code and dozens of LLMs: you can switch model IDs and run A/B tests on quality or latency without rewriting core integration logic.

This is useful for products that want to avoid a single-vendor dependency. Compare with direct APIs from ChatGPT/OpenAI, Claude, and Gemini. Related terms: API, prompt, and AI model.
