OpenRouter now routes 100 trillion tokens per month, up from 5 trillion weekly six months ago to 25 trillion weekly today—a fivefold increase.
On May 26, the company announced a $113 million Series B round led by CapitalG, Alphabet's growth fund, doubling its valuation to $1.3 billion in a year.
What is OpenRouter?
It's a middleware for large language models. Instead of integrating multiple APIs from OpenAI, Anthropic, Google, and others, developers use a single interface to access over 400 models. OpenRouter handles formatting, billing, and rate limits, and can recommend the best model for each task based on cost and accuracy.
The platform now has 8 million users.
Why Google invested in a model-agnostic router
At first glance, it seems odd: Google has its own Gemini models, yet it led a round for a service that encourages multi-model use. But the logic is clear: enterprises are not locking themselves into a single model provider.
"Enterprises will no longer lock themselves into one model vendor like they did with SaaS."
The industry moves too fast; today's best model could be surpassed next month. Multi-model strategies are already the norm, not the future. Google's investment is a bet on the distribution layer rather than a preference for OpenRouter.
Notable co-investors
Alongside CapitalG, the round included NVIDIA's venture arm NVentures, Snowflake, Databricks, MongoDB, ServiceNow's venture arm, and existing backers a16z, Menlo Ventures, and Sequoia.
These investors span data infrastructure (Snowflake, Databricks, MongoDB), compute (NVIDIA), and enterprise software—all betting on the model-calling gateway. As AI moves into production, model routing becomes a critical tollbooth for AI traffic.
Is the business sustainable?
OpenRouter has not disclosed revenue. It takes a cut from each API call, so volume drives profit. Weekly 25 trillion tokens is impressive, but the moat is shallow: model providers could build their own routing, or large clients might bypass the middleman.
However, the fivefold growth in six months and 8 million users suggest strong demand. The question is whether OpenRouter can consistently offer better cost and model selection than customers could achieve on their own.
