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.

Frequently asked questions

Straight answers about how Ramp Router works, who it’s for, and how to get started.

What is an LLM router?

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.

How does it work?

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.

Why is Ramp building an LLM router?

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.

What models do you support?

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.

How much does it cost?

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.

Do I need to be a Ramp customer?

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.

What's the difference between using Ramp Router and going direct with a provider?

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.

Do I have to rewrite my code to use this?

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.

Who should use this?

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.

What happens if a provider has an outage or rate-limits me?

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.

How does Ramp Router handle my data and credentials?

Please see the Ramp Router Privacy Policy for information on how Ramp manages personal information.

Tokens are money. Save both.

Model providers make more when you use more frontier intelligence. Ramp wins when you spend less.
