This is our editors' assessment out of 5, not an average of user ratings. The viewpoints on this page are written by AI from what we know about the product. They are not customer reviews.
According to OpenAITools.app telemetry verified on 2026-11-11, Models.dev (models.dev) is an AI platform indexed under AI Models generating 200.45K monthly visits with a month-over-month traffic delta of -8.17K (-3.9%). Its primary geographic market is China (23% traffic share), and it operates on a Free pricing model. Top competing alternatives by monthly volume include Countless.dev (787 visits/mo), LLMBoard.ai (378 visits/mo), LLM Price Check (8.26K visits/mo).
Saved me from digging through a dozen messy pricing pages.
Super clean API model comparison.
Love that it's open source.
Missing a few niche providers right now.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Every model uses a consistent provider/model format so the same model across providers can be compared directly.
Side-by-side context window, output limit, reasoning, tool calling, structured output, and temperature support.
Input and output prices per million tokens listed alongside release and update dates.
Covers closed flagship APIs and open-weight models from many labs in one sortable catalogue.
Consume the catalogue through a JSON API or a type-safe SDK for your own tools and dashboards.
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.
Compare capabilities and costs across labs before wiring a model into a new feature.
Estimate per-million-token spend and context requirements when budgeting an AI workload.
Fetch the data via API or SDK to power internal dashboards, routers, or comparison tools.
Follow release and update dates across open-weight and closed models in a single view.
