Overview
OpenRouter — Best for developers who need multi-model access through one API.
OpenRouter provides one API for routing requests across many AI model providers, making it easier to compare models, control costs, and add fallback behavior.

Essential for multi-model production apps
We use OpenRouter to A/B test model performance in production without changing our application code. Swapping from GPT-4o to Claude 3.5 Sonnet to Gemini is just a model string change. The fallback routing has saved us during provider outages twice. For any serious AI application, the single API surface is invaluable.

Best way to prototype with multiple models
When building our product we needed to evaluate 8 different models for our use case without signing up for 8 APIs. OpenRouter let us do that with one account and one SDK. The cost tracking per model is helpful. My only wish is better streaming latency — there's occasional overhead from the proxy layer that adds noticeable delay.
