Ramp Launches "Router" to Direct Tasks to the Cheapest, Fastest AI
Fintech startup Ramp rolled out an API service that dynamically routes user prompts to the most cost-effective model.
Not every task requires a massive, compute-heavy AI model. Ramp has launched a new developer tool called Router, designed to act as an automated traffic director for large language models.
A model router inspects an incoming request and decides on the fly which AI model should handle it. If a user asks a simple question like "What is the date of this receipt?", the router sends it to a fast, cheap model. If the request requires multi-step math or deep synthesis, it sends it to a heavy-duty frontier model.
This setup tackles two of the biggest operational challenges in AI development: latency (the delay between sending a request and getting an answer) and runaway API token costs.
What this means for you as a builder
As you build complex agents that handle varied workloads, avoid hardcoding a single premium model for every single step. Splitting simple tasks like classification or text extraction into lightweight models can cut your monthly operating costs by over 70% while making your app feel instant.
