Choose a Group and Model
A model determines the capability. A group determines which routes and models the key can use and which multiplier applies. Both must match.
Start from the live catalog
- Open the Model Catalog.
- Search for the model you plan to use.
- Check its supported endpoint or protocol.
- Check the available group and multiplier.
- Compare input, output, and cache prices.
- Return to the key page and select the matching group.
Model IDs, availability, groups, and prices can change, so this documentation does not maintain a static catalog.
Copy the exact model ID
Preserve capitalization, hyphens, and any provider prefix. vendor/model-name is not the same as model-name. The safest method is to call GET /v1/models with the same key and copy an id from its response.
