## Why it is interesting

Enterprises use many models across many providers. Managing cost, latency, governance, and failover across them is messy. OpenRouter abstracts it into one marketplace and routing layer. - Multi-model strategies are now standard in production AI. - Cost and reliability optimization across models is a real operational pain. - Governance — who can call which model with what data — is a compliance requirement. OpenRouter raised $113M Series B in May 2026, led by CapitalG, to route enterprise AI inference across models with governance and optimization.
