Ramp Router
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.

Router chooses the right model for the job,
then applies 100+ optimizations to get it done for less.
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.
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.

Insights
Straight answers about how Ramp Router works, who it’s for, and how to get started.
An LLM router is one API endpoint for accessing multiple AI models. Instead of wiring your app to one provider at a time, you send requests through our router which can choose the right model for the job based on quality, cost, and availability.
Your request goes to Ramp Router first. We’ll authenticate the request and help you track the usage, model, provider, and cost. We’ll automatically route eligible requests to a more cost-efficient tier when it won't affect quality.
Saving you time and money is the whole reason Ramp exists. AI tokens are the fastest-growing spend category, and we want every token you use to be worth it.
Ramp Router supports the latest models from OpenAI, Anthropic, and Gemini plus select open-source models, including Kimi. We regularly add support for new models as they become available.
Ramp Router is free to use at launch. You’ll pay list price for the tokens you use. As a thank you to our early access users, the first 500 people invited will receive $100 in promotional credits to get started. Subject to offer terms.
No. You don’t need a Ramp card, a company account, or even an LLC. We’re inviting an initial group of users to get early access. Join the waitlist to request your spot.
Going direct usually means choosing one provider, one model catalog, and one pricing structure yourself. Ramp Router gives you one endpoint across eligible models and can route requests to the lowest-cost option that meets the quality bar. As new models launch, change prices, and performance change, Ramp Router will adapt automatically without requiring you to constantly rework your integration.
No. Ramp Router has an OpenAI-compatible API, so if you’re already using the OpenAI SDK or another OpenAI-compatible framework (which is basically all of them!), switching should be a one-line change: update your base URL to Ramp Router’s endpoint.
Router is for anyone who wants to get more from AI without overpaying for it. It helps you get the same work done for less, whether you’re testing an idea on your own, building for a team, or managing AI across an enterprise. We’re inviting an initial group now. Request an invite.
If a provider goes down or rate-limits you, Ramp Router can route eligible requests to another available model, so your app has a fallback when one provider cannot serve it.
Please see the Ramp Router Privacy Policy for information on how Ramp manages personal information.
Model providers make more when you use more frontier intelligence. Ramp wins when you spend less.
