About the service
A platform for evaluating and observing AI products: request logging, datasets, automated scorers and side-by-side comparison of prompt and model versions. It lets you run experiments against regression sets and see whether a change actually improved output quality. It includes a prompt playground and SDKs for wiring evals into CI.
