Models.dev is an open-source database of AI model specifications, pricing, and capabilities.
The project addresses the absence of a single comprehensive source for information about available AI models. It maintains structured data about model metadata, provider-specific serving details, pricing, and capabilities, organizing this information in TOML files by provider and model. The data powers both a web interface and an API that allows lookups by model ID or provider, with provider-agnostic model facts available separately from provider-specific details like pricing and context limits. Provider logos are served as SVG files through the same API.
The tool suits teams building AI applications that need to query model specifications, compare offerings across providers, or integrate model metadata into their own systems. The API design distinguishes between model-only metadata and provider-specific information, allowing callers to fetch just what they need. The project is designed for community contribution, with a clear structure for adding new providers, models, and updating existing data.
The project maintains active engagement with its data through community contributions, accepting pull requests to keep model specifications and pricing current. Development activity shows consistent attention to the repository's core function as a living database rather than a static reference.
