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. - **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. **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 [Profile (Markdown)](https://openaitools.app/tool/models-dev.md) ## ToolCenter ToolCenter solves a very practical problem: the AI tool market is enormous and changes weekly, so finding a trustworthy option for a specific job is hard. The site groups thousands of tools into clear categories such as AI chatbots and assistants, image and design, video and animation, writing and content, developer tools, audio and music, marketing, business and productivity, education and research, 3D and modelling. Each listing carries a description, category tags, pricing signal and a link out to the product, and the directory highlights trending entries, recently added tools and editor's picks. Alongside the browsable catalog, ToolCenter adds editorial structure. There are category rankings and leaderboards, including model rankings and a monthly LLM leaderboard, plus comparison pages and articles that explain how tools differ. A prompts section collects reusable prompts, and 'browse by task' entry points let you start from the job you need to finish — create images, make videos, build with AI — rather than a tool name you may not know. Free tool collections are also curated for people who want no-cost options. ToolCenter is free to use and is funded by an editorial model where vendors can submit or partner their tools for listing. It positions itself as a curated rather than exhaustive directory, so inclusion is selective. Because rankings and listings change frequently, treat the directory as a discovery and orientation layer rather than a definitive verdict, and always validate a specific tool against its own site before committing budget. **Pricing & Plans:** ToolCenter is free to browse. Vendors can submit their tools, and there is a partnership route for listings; there is no cost for users to search, compare or read editorial content. - **Curated catalog:** Browse thousands of AI and productivity tools organised into clear categories, from chatbots to video, design, code and audio. - **Rankings and leaderboards:** See category rankings, model rankings and a monthly LLM leaderboard to gauge which tools are currently leading. - **Task-based browsing:** Start from the outcome you need — create images, make videos, build with AI — instead of searching by tool name. - **Prompts and articles:** Access a prompt library plus comparison articles and guides that explain how similar tools differ. - **Trending and editor's picks:** Follow trending tools, recently added entries and verified editor's choices to spot new options quickly. **Strengths:** Brings thousands of tools into one searchable, categorised place.; Rankings, leaderboards and comparison articles add editorial guidance beyond a plain list.; Task-based browsing helps you start from a goal rather than a tool name.; Free to use for anyone browsing or comparing tools. **Limitations:** As a directory it hosts listings rather than the tools themselves, so you still need to try products on their own sites.; Selection is curated and can be influenced by submissions and partnerships.; Fast-changing rankings mean any specific standing can go out of date quickly.
