About Models.dev

Models.dev is an open-source database that collects specifications, pricing, and capabilities for AI models in one place. The project was started as a community-contributed effort because no single database covered all available AI models. The maintainers also use it internally in opencode.

The data can be read through a public API at models.dev/api.json, with optional filtering by model type. Model-only metadata, provider-specific serving details, and provider logos are available through separate endpoints. The data is stored in the GitHub repository as TOML files and is maintained with community contributions. The source states that the project needs help keeping the data up to date.

Models.dev FAQ

How can I access the data programmatically?
The data can be accessed through an API. Running curl https://models.dev/api.json returns the catalog, and the type parameter can filter results by one or more comma-separated model types or return all types.
Where can I find metadata about a model that is independent of any provider?
Provider-agnostic model metadata is available at https://models.dev/models.json. The catalog.json endpoint returns both provider endpoints and model-only metadata in one response.
How can I contribute data?
Contributors add or update TOML files in the repository. Model-only facts go in the models/ directory, and provider-specific details such as pricing go in the providers/ directory.
