Ramp AI Router: Choose the Right Model for Every Request, Cut Costs by 30%
Ramp released its AI Router, which automatically selects the best language model for each request, reducing LLM costs by 30% while maintaining performance. Previously used internally for over 100 AI use cases, the tool is now available to the public.
Ramp Router
The right model forevery request.
We built Router to keep 100+ AI use cases at Ramp on the right model. It cut our LLM costs by 30% while making our features smarter and faster. Now we’re opening it up to everyone.

Routing is just the start.
Router chooses the right model for the job, then applies 100+ optimizations to get it done for less.
Pay for what the job needs. Nothing more.
Every week, the price-intelligence-latency frontier shifts. Router tests each new model on real work, then automatically sends every request to the lowest-cost model that clears its quality bar.

Implement in a few lines of code
One endpoint gives you leading closed and open models. Router handles routing, fallbacks, and provider updates so you benefit from new models without rewriting your application.
