PortKey Just Raised $15M — Here's What That Means for Your AI Costs

PortKey just raised $15 million. OpenRouter has been quietly growing its model catalog to 300+ models. And every major AI infrastructure company is pitching the same thing: we'll handle the routing. That's worth examining. What $15M buys you in AI routing PortKey's pitch is AI gateway infrastructure — centralized routing, observability, and cost optimization for teams spending real money on API calls. They're not wrong about the problem. AI API costs are genuinely chaotic right now: Claude Opus 4.6 at $0.015/1K tokens for a task that Gemini 3 Flash handles at $0.0005 Teams routing everything through the same model because switching is engineering work Zero visibility into which queries actually needed the expensive model $15M is a serious bet that this problem is large enough to warrant dedicated infrastructure. The routing math hasn't changed Here's the thing PortKey's raise confirms rather than invents: Most AI queries don't need the best model. They never did. A few benchmarks I ran
