[Models.dev](https://models.dev) is a comprehensive open-source database of AI model specifications, pricing, and capabilities.

There's no single database with information about all the available AI models. We started Models.dev as a community-contributed project to address this. We also use it internally in [opencode](https://opencode.ai).

## API

You can access this data through an API.

```bash
curl https://models.dev/api.json
```

Use the **Model ID** field to do a lookup on any model; it's the identifier used by [AI SDK](https://ai-sdk.dev/).

### Logos

Provider logos are available as SVG files:

```bash
curl https://models.dev/logos/{provider}.svg
```

Replace `{provider}` with the **Provider ID** (e.g., `anthropic`, `openai`, `google`). If we don't have a provider's logo, a default logo is served instead.

## Contributing

The data is stored in the repo as TOML files; organized by provider and model. The logo is stored as an SVG. This is used to generate this page and power the API.

We need your help keeping the data up to date.

### Adding a New Model

To add a new model, start by checking if the provider already exists in the `providers/` directory. If not, then:

#### 1. Create a Provider

If the provider isn't already in `providers/`:

1. Create a new folder in `providers/` with the provider's ID. For example, `providers/newprovider/`.
2. Add a `provider.toml` with the provider details:

```toml
name = "Provider Name"
npm = "@ai-sdk/provider" # AI SDK Package name
env = ["PROVIDER_API_KEY"] # Environment Variable keys used for auth
doc = "https://example.com/docs/models" # Link to provider's documentation
```

If the provider doesn’t publish an npm package but exposes an OpenAI-compatible endpoint, set the npm field accordingly and include the base URL:

```toml
npm = "@ai-sdk/openai-compatible" # Use OpenAI-compatible SDK
api = "https://api.example.com/v1" # Required with openai-compatible
```

#### 2. Add a Logo (optional)

To add a logo for the provider:

1. Add a `logo.svg` file to the provider's directory (e.g., `providers/newprovider/logo.svg`)
2. Use SVG format with no fixed size or colors - use `currentColor` for fills/strokes

Example SVG structure:

```svg

```

#### 3. Add a Model Definition

Create a new TOML file in the provider's `models/` directory where the filename is the model ID:

```toml
name = "Model Display Name"
attachment = true # or false - supports file attachments
reasoning = false # or true - supports reasoning / chain-of-thought
tool_call = true # or false - supports tool calling
temperature = true # or false - supports temperature control
knowledge = "2024-04" # Knowledge-cutoff date
release_date = "2025-02-19" # First public release date
last_updated = "2025-02-19" # Most recent update date

[cost]
input = 3.00 # Cost per million input tokens (USD)
output = 15.00 # Cost per million output tokens (USD)
cache_read = 0.30 # Cost per million cached read tokens (USD)
cache_write = 3.75 # Cost per million cached write tokens (USD)

[limit]
context = 200_000 # Maximum context window (tokens)
output = 8_192 # Maximum output tokens

[modalities]
input = ["text", "image"] # Supported input modalities
output = ["text"] # Supported output modalities
```

#### 4. Submit a Pull Request

1. Fork this repo
2. Create a new branch with your changes
3. Add your provider and/or model files
4. Open a PR with a clear description

### Validation

There's a GitHub Action that will automatically validate your submission against our schema to ensure:

- All required fields are present
- Data types are correct
- Values are within acceptable ranges
- TOML syntax is valid

### Schema Reference

Models must conform to the following schema, as defined in `app/schemas.ts`.

**Provider Schema:**

- `name`: String - Display name of the provider
- `npm`: String - AI SDK Package name
- `env`: String[] - Environment variable keys used for auth
- `doc`: String - Link to the provider's documentation
- `api` _(optional)_: String - Required only when using `@ai-sdk/openai-compatible` as the npm package

**Model Schema:**

- `name`: String — Display name of the model
- `attachment`: Boolean — Supports file attachments
- `reasoning`: Boolean — Supports reasoning / chain-of-thought
- `tool_call`: Boolean - Supports tool calling
- `temperature`: Boolean — Supports temperature control
- `knowledge` _(optional)_: String — Knowledge-cutoff date in `YYYY-MM` or `YYYY-MM-DD` format
- `release_date`: String — First public release date in `YYYY-MM` or `YYYY-MM-DD`
- `last_updated`: String — Most recent update date in `YYYY-MM` or `YYYY-MM-DD`
- `cost.input` _(optional)_: Number — Cost per million input tokens (USD)
- `cost.output` _(optional)_: Number — Cost per million output tokens (USD)
- `cost.cache_read` _(optional)_: Number — Cost per million cached read tokens (USD)
- `cost.cache_write` _(optional)_: Number — Cost per million cached write tokens (USD)
- `limit.context`: Number — Maximum context window (tokens)
- `limit.output`: Number — Maximum output tokens
- `modalities.input`: Array of strings — Supported input modalities (e.g., ["text", "image", "audio", "video", "pdf"])
- `modalities.output`: Array of strings — Supported output modalities (e.g., ["text"])

### Examples

See existing providers in the `providers/` directory for reference:

- `providers/anthropic/` - Anthropic Claude models
- `providers/openai/` - OpenAI GPT models
- `providers/google/` - Google Gemini models

### Working on frontend

Make sure you have [Bun](https://bun.sh/) installed.

```bash
$ bun install
$ cd packages/web
$ bun run dev
```

And it'll open the frontend at http://localhost:3000
