Overview

Models.dev is an open-source database that serves as a comprehensive reference for AI models. It aggregates specifications, pricing, and features from a wide range of providers and labs, enabling users to compare models side by side. The platform covers key attributes such as context window size, output token limits, reasoning capabilities, tool calling support, structured output, temperature settings, and weight availability. It also includes pricing per million tokens, release dates, and the number of providers offering each model.

Full Description ▼

The database is designed to be a practical tool for developers, ML engineers, and researchers who need to evaluate models for their projects. Each model has a dedicated page with detailed information, and the main table allows for quick scanning and filtering. The data is continuously updated to reflect new releases and pricing changes, making it a valuable resource in the fast-moving AI ecosystem.

As a free and open-source project, Models.dev relies on community contributions to keep the information accurate and comprehensive. It is hosted on GitHub, where users can contribute updates or report issues. The project aims to reduce the friction of researching AI models by providing a single, searchable source of truth.
