Auto Router

Your prompt will be processed by a meta-model and routed to one of dozens of models (see below), optimizing for the best possible output.

To see which model was used, visit [Activity](/activity), or read the `model` attribute of the response. Your response will be priced at the same rate as the routed model.

Learn more, including how to customize the models for routing, in our [docs](/docs/guides/routing/routers/auto-router).
