Expense management firm Ramp rolls out its own AI model routing tool
Corporate expense platform Ramp launched an AI model routing service called Router on Wednesday, letting users switch between large language models through a single API. The service is currently US-only and free through the end of 2026.
Ramp, the corporate expense management platform, announced on Wednesday evening the launch of Router, a new AI model routing service that lets companies and individual users access and switch between multiple large language models via a single API. Ramp says it has relied on this same routing technology internally for its own AI needs over the past three years.
The service is currently available only in the United States. It will be free to use through the end of 2026, though customers still have to cover the underlying AI inference costs, and new users get a $26 credit as a launch offer. Ramp has not disclosed what it will charge once the free period ends.
Functionally, Router resembles OpenRouter, though it currently offers a narrower selection of models. Users can access models from OpenAI, Anthropic, DeepSeek, Moonshot, Minimax, Nvidia, xAI, and Z.ai. The service also includes several routing strategies, such as prioritizing cheaper flex-usage tiers from providers, directing only more difficult queries to costlier models, or selecting models automatically based on user-defined benchmarks. A dashboard shows customers details like token spend, cost, latency, and fallback attempts.
By default, Router retains model inputs, outputs, and tool calls for one year, though users can opt out of this data retention. Ramp says it strips personally identifiable information before using any retained data to improve its product.
The launch gives Ramp a foothold in the fast-growing AI inference market while complementing its existing suite of AI token spend and usage-monitoring tools. If Router gains the kind of traction OpenRouter has seen, it could also help Ramp build relationships with AI labs and inference providers, potentially opening a new avenue for selling its core expense management products. Ramp raised $750 million in June at a $44 billion valuation.
