Overview

OpenRouter is an AI model exchange that routes inference requests across hundreds of large language models and providers[3]. The platform released an MCP server that gives coding agents live access to its model catalog, benchmarks, pricing, documentation and test inference so agents can pick models from current data[2]. OpenRouter also launched an updated Auto router that selects models using cross-domain benchmarks and real aggregate spending patterns on its platform, adapting automatically as community preferences shift[1].

OpenRouter builds a unified API that aggregates large language models from many providers behind one interface compatible with the OpenAI SDK, adding distributed infrastructure with automatic fallback when a provider goes down, edge-based inference for lower latency, data policy controls that restrict prompts to approved models and providers, and team spend controls with per-key limits. [12]

Growth & traction

OpenRouter reports processing more than 200 trillion tokens per month across 400+ active models from 70+ providers, with over 10 million global users and more than 250,000 apps built on the platform. [11]
