Finest

Finest is an AI gateway that automatically determines whether a less‑expensive AI model can handle each request without sacrificing quality, switching to the cheaper option only when evidence shows it performs equally well, and displaying the costs of both the original and switched models for every request. By continuously testing routes against new model releases and applying the lowest‑cost configuration that meets your quality bar, Finest helps developers reduce API spend while maintaining performance.

The service provides a single endpoint that works with your existing SDK, charges nothing if no savings are realized, and takes 25 % of the proven cost reductions. In just a few minutes, you can start lowering your AI API bill without changing your application’s code.
