GitHub - sst/models.dev: An open-source database of AI models. (original) (raw)

Models.dev logo

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.

API

You can access this data through an API.

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.

Logos

Provider logos are available as SVG files:

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:
    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:
    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:

3. Add a Model Definition

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

If the model ID contains /, use subfolders. For example, for the model ID openai/gpt-5, create a folder openai/ and place a file named gpt-5.toml inside it.

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 structured_output = true # or false - supports a dedicated structured output feature 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 open_weights = true # or false - model’s trained weights are publicly available

[cost] input = 3.00 # Cost per million input tokens (USD) output = 15.00 # Cost per million output tokens (USD) reasoning = 15.00 # Cost per million reasoning tokens (USD) cache_read = 0.30 # Cost per million cached read tokens (USD) cache_write = 3.75 # Cost per million cached write tokens (USD) input_audio = 1.00 # Cost per million audio input tokens (USD) output_audio = 10.00 # Cost per million audio output tokens (USD)

[limit] context = 400_000 # Maximum context window (tokens) context = 272_000 # Maximum input tokens output = 8_192 # Maximum output tokens

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

[interleaved] field = "reasoning_content" # Name of the interleaved field "reasoning_content" or "reasoning_details"
