OpenRouter

OpenRouter provides an AI model gateway and marketplace that lets developers and businesses access hundreds of models through one interface. It supports text, image, audio, speech, transcription, embedding, and video workloads, with provider failover and cost and latency optimization. Teams can manage workspaces, spending, guardrails, and zero-data-retention policies while tracking usage across models. Users include NVIDIA, Zoom, and Lovable.

Founded in 2023 by Alex Atallah and Louis Vichy, OpenRouter is led by Atallah as CEO. Its engineering addresses differences between providers serving the same model. Auto Exacto reevaluates providers roughly every five minutes using throughput, tool-call telemetry, and controlled benchmarks. It moves statistical quality outliers behind other providers while preserving price, latency, and user preferences within each tier, making provider selection responsive to measured performance.

In August 2026, OpenRouter reported processing more than 10 trillion tokens daily for a community of over 10 million developers and companies. It raised a $113 million Series B led by CapitalG in May 2026. Stripe announced an acquisition agreement on August 19, 2026; the transaction remained subject to customary closing conditions. OpenRouter said its name, product, and roadmap would continue.
