OpenRouter Secures $113M, Valued at $1.3B

OpenRouter, a unified gateway for Large Language Models, has secured $113 million in Series B funding. This round was led by CapitalG, the venture fund of Google's parent company, Alphabet, and values the startup at approximately $1.3 billion. This valuation marks a significant increase from its Series A round in June 2025.

The company's AI gateway has seen a surge in popularity, driven by the shift in AI development towards agents. OpenRouter enables enterprises and other AI users to efficiently select different models for specific tasks, optimizing costs, reasoning, and accuracy.

With access to over 400 AI models from providers like Anthropic, Google, and OpenAI, OpenRouter boasts 8 million global users. The platform processes an impressive 100 trillion tokens per month, a fivefold increase from six months ago.

OpenRouter's success suggests a future where AI models are interchangeable engines for various tasks. This indicates companies' preference for multi-model strategies over standardization with a single vendor, mirroring their approach to SaaS providers.
