What is OpenRouter?
OpenRouter is a service that puts language models from many vendors behind one OpenAI-compatible API and a single account.
What does it do?
Routes requests to models across providers through one endpoint and key, with fallbacks when a provider is down or rate-limited. Reports per-model cost, latency and throughput, and includes a chat interface for trying models.
Who is it for?
Developers and teams building on LLMs who want to swap or compare models without signing up with each vendor, and prototypers chasing newly released models.
What are the alternatives to OpenRouter?
Claude, ChatGPT and Gemini are chat products tied to their maker's own models. T3 Chat is a multi-model chat client; Perplexity is search-focused rather than an API layer.
