How to use

Modelspage lets you browse models, compare providers, and explore rankings. Open a model for its specifications and provider prices.

API

You can access provider data, provider-agnostic model metadata, or the combined catalog through JSON endpoints. Specialized model types are omitted by default; the site includes all model types.

Logos

Provider logos are available at /logos/{provider}.svg where {provider} is the provider ID. Lab logos are available at /logos/labs/{lab}.svg.

Upstream SDK

The models.dev SDK provides typed catalog queries and upstream snapshots for offline use.

Contribute

The model catalog is stored in GitHub as TOML files organized by provider and canonical model.
