OpenRouter, the platform that aggregates access to over 100 AI models, has closed a $113 million Series B funding round, according to the company's official announcement.
OpenRouter provides a single, standardized API that lets developers route requests across models from OpenAI, Google, Anthropic and open-source providers without building separate integrations for each. According to the announcement, the platform lets developers select models based on cost, speed, or capability for a given task, and switch between them without changing application code.
Key features highlighted in the announcement include:
- Unified Access: A single integration for access to more than 100 models, including offerings from OpenAI, Google and Anthropic, as well as open-source models.
- Cost Optimization: Tools for comparing price and performance across providers.
- Consolidated Billing: Pay-as-you-go billing across all supported model providers.
- Model Flexibility: The ability to swap models without rewriting application code.
OpenRouter said it plans to use the new funding to expand its model catalog, add platform features, and scale infrastructure to meet growing demand from developers and enterprises.
The round underscores continued investor interest in infrastructure that sits between developers and the growing number of foundation models on the market, as teams look for ways to avoid being locked into a single provider's API.
