[modelparams.dev](https://modelparams.dev) is an open-source database that lists the parameters available for popular AI models. It is heavily inspired on [models.dev](https://github.com/anomalyco/models.dev) and we use it at [Manifest](https://manifest.build/).

## API

You can access this data through an API.

```

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

```

The catalog follows the [Model Parameters convention](docs/model-parameters-schema.md).

The generated JSON Schema is available at

`https://modelparams.dev/api/v1/schema.json`.

## Adding a model or a parameter

See [CONTRIBUTING.md](CONTRIBUTING.md). The short version:

1. Pick a unique ID: `/` for the API-key variant, `/-subscription` for the subscription variant. Example: `mistral/mistral-large`.

2. Add a YAML file at `models//.yaml` (or `models//-subscription.yaml`).

3. Open a PR. CI validates against the schema and rebuilds.

## Local development

```bash

npm install

npm run dev          # http://localhost:3000

npm run build        # → dist/

npm run validate     # check every YAML

npm test

```
