Founded in 2023, OpenRouter is a global AI infrastructure company that offers developers a unified API to access over 300 large language models from more than 60 providers. The platform acts as a gateway, using intelligent model routing and automatic fallbacks to eliminate vendor lock-in for users building with AI. It also consolidates billing across providers and includes features such as response healing and custom data policies.
The company's platform processes more than 100 trillion tokens per year, with a user base exceeding 5 million globally. This scale positions the service as a significant intermediary in the AI development ecosystem, where managing access to multiple, rapidly evolving models presents a consistent technical and administrative challenge.
OpenRouter secured $40 million in Series A funding to support its operations. Its work spans core technical domains including API development, intelligent routing systems, and consolidated billing infrastructure. The company's geographic presence is global, serving users across the software development and enterprise software verticals.
