OpenRouter is an American artificial intelligence company that operates a platform for accessing and routing requests to large language models and other generative artificial intelligence models. The platform provides a unified application programming interface (API) through which developers can access models from multiple developers and inference providers.^[1]

In August 2026 Bloomberg and The Wall Street Journal reported that Stripe, Inc. had finalized a deal to acquire OpenRouter for more than $7 billion.^[2]^[3]

History

OpenRouter was founded in 2023 by Alex Atallah and Louis Vichy and is based in New York City. In 2025, the company raised $12.5 million in a seed round led by Andreessen Horowitz, followed by a $28 million Series A round led by Menlo Ventures.^[4] In May 2026, it raised $113 million in a Series B round led by CapitalG, valuing the company at approximately $1.3 billion.^[1]

Platform

Developers can select individual models or route requests between models based on factors including price and performance.^[4] The platform provides access to more than 400 models, including models developed by OpenAI, Anthropic, and Meta.^[5]

Compatible AI coding software

OpenRouter can be used as a model provider or inference backend for a number of AI-assisted software development tools, notable examples include:^[6]

Supported models

OpenRouter provides access to hundreds of artificial intelligence models, including large language models and models for image generation, video generation, speech synthesis, transcription, embeddings, reranking, and audio generation. Notable models and model families available through the service include:^[24]
