OpenRouter announced it has closed a $113 million Series B financing led by CapitalG, Alphabet’s independent growth fund, at a moment when the company reports weekly token throughput of 25 trillion. That figure marks a five-fold increase from the 5 trillion tokens per week the platform was processing six months ago.
Investors in the round included NVentures, NVIDIA’s venture capital arm, ServiceNow Ventures, MongoDB Ventures, Snowflake Ventures and Databricks Ventures, along with existing backers Andreessen Horowitz and Menlo Ventures. The company said it will allocate the new capital to broaden its routing, governance and optimization capabilities as customers move AI into production environments.
OpenRouter’s infrastructure is built to manage and optimize inference across a broad model ecosystem. The platform routes requests and orchestrates inference across more than 400 models supplied by providers such as Anthropic, Google, OpenAI, xAI and DeepSeek. According to the company, its API is used by more than 8 million users worldwide, spanning AI-native startups and large enterprises.
A 2026 Deloitte study cited by the company notes that 67% of enterprises consume over one billion tokens per month, underscoring the scale at which large organizations are engaging with generative AI workloads.
The vendor describes its value proposition as enabling organizations to route traffic across models and providers from a single API to optimize for cost, latency and capability. Platform controls include per-request data handling policies, team-level access and routing permissions, spend visibility and audit-friendly usage reporting.
"Running inference at scale is fundamentally a multi-model problem. The era of picking a single model is over," said Alex Atallah, CEO and co-founder of OpenRouter. "Success now depends on continuously routing across a changing market. Because OpenRouter sits in the flow of production traffic, we can optimize every request for cost, performance, and reliability in real time."
Management framed the funding as a means to accelerate product development in routing, governance and optimization so that enterprises deploying AI at scale can better control costs, meet latency requirements and maintain oversight of data handling and access. The company’s emphasis on single-API routing and model-agnostic controls positions it as an infrastructure layer intended to sit between production applications and a shifting set of model providers.
OpenRouter reported rapid growth in token processing and expanded investor interest from strategic cloud and data-platform venture arms, reflecting both usage momentum and investor appetite for infrastructure that helps enterprises manage multi-provider AI deployments.
