modelparams.dev

An open, community-maintained catalog of LLM model parameters.

modelparams.dev is an open-source database that lists the parameters available for popular AI models. It is heavily inspired on models.dev and we use it at Manifest.

API

You can access this data through an API.

curl https://modelparams.dev/api/v1/models.json

The catalog follows the Model Parameters convention. The generated JSON Schema is available at https://modelparams.dev/api/v1/schema.json.

Adding a model or a parameter

See CONTRIBUTING.md. The short version:

1. Pick a unique ID: <provider>/<model> for the API-key variant, <provider>/<model>-subscription for the subscription variant. Example: mistral/mistral-large.
2. Add a YAML file at models/<provider>/<model>.yaml (or models/<provider>/<model>-subscription.yaml).
3. Open a PR. CI validates against the schema and rebuilds.
