OpenRouter’s $1.3B valuation shows model routing is becoming AI infrastructure

As companies use more than one AI model, routing becomes a real infrastructure problem.

What happened

OpenRouter more than doubled its valuation to $1.3B within a year.

The company sits in the model-access and routing layer, helping developers work across different AI models.

Why it matters

Companies do not want to be locked into one model forever. They need ways to compare cost, quality, latency, and reliability.

The bigger picture

The AI stack is becoming multi-model. Infrastructure that handles routing, evaluation, monitoring, and fallback logic may become increasingly valuable.
