## Overview

Models.dev exists to answer a very practical developer question: which model should I use, and what will it cost? The site organises every entry under a canonical identifier in the form provider/model, so the same model served by several providers can be compared directly rather than guessed at. Columns cover context window, maximum output, whether input and output are supported, reasoning, tool calling, structured output, temperature control, open versus closed weights, price per million tokens, and release and update dates.

Because model releases move fast, the catalogue is built to stay current, with sortable and searchable tables that let you scan by lab or provider and filter down to what matters. Entries include both closed flagship models and open-weight alternatives, making it useful for cost planning as well as capability research.

The project is open source and free to use, and it is intended to be consumed programmatically. Developers can pull the catalogue into their own tooling through a JSON API or a type-safe SDK, which makes it a practical backend for dashboards, routing logic, or internal cost calculators rather than just a reference page to browse.

## Pricing & Plans

Models.dev is free and open source. It is a reference database, so the prices it lists are the per-million-token rates charged by the model providers themselves, not a fee for using the site.

## Key Features & Capabilities

- **Canonical model identifiers:** Every model uses a consistent provider/model format so the same model across providers can be compared directly.
- **Specification comparison:** Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
- **Pricing transparency:** Input and output prices per million tokens listed alongside release and update dates.
- **Open and closed models:** Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.
- **Developer access:** Consume the catalogue through a JSON API or a type-safe SDK for your own tools and dashboards.

## Primary Use Cases

- **Model selection (Developer):** Compare capabilities and costs across labs before wiring a model into a new feature.
- **Cost planning (Engineering manager):** Estimate per-million-token spend and context requirements when budgeting an AI workload.
- **Embedding the catalogue (Tooling builder):** Fetch the data via API or SDK to power internal dashboards, routers, or comparison tools.
- **Tracking the field (Researcher):** Follow release and update dates across open-weight and closed models in a single view.

## Strengths

- Free and open source with no account required
- Consistent canonical identifiers make cross-provider comparison reliable
- Covers pricing, limits, and capabilities in one sortable table
- Available as a JSON API and type-safe SDK for programmatic use

## Limitations

- It is a reference catalogue, not an inference or hosting service
- Data quality depends on community and maintainer updates keeping pace with releases
- Interface is aimed at developers and offers little guidance for non-technical users
