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) ## Perchance Perchance is an online sandbox where people build generators. Its core idea is simple: you write lists of possible values, and the platform selects from them at random to produce text, structured data or interactive results. This makes it easy to create name generators, randomizers, prompt makers or full random tables without complex coding. Because generators also support HTML, CSS and JavaScript, creators can turn the same pages into rich interactive tools, including story generators, character creators, RPG utilities, image generators and AI chat experiences. Everything runs in the browser and pages can be shared with a single link. Perchance has grown into a large community platform where thousands of public generators are available to use for free. It suits hobbyists, writers, game masters and developers who want a fast way to generate random content or prototype a small web app without a backend. **Pricing & Plans:** Perchance is free to use. Building and publishing generators costs nothing; you only need an account. There is no mandatory paid plan for typical use, though the site may surface community content and ads. - **List-Based Generator Syntax:** Define items as lists and let Perchance pick randomly, producing names, items, prompts or full paragraphs. - **HTML, CSS & JavaScript Support:** Customize how your generator looks and behaves with standard web markup, styling and scripts. - **One-Click Publishing:** Publish generators instantly so anyone can open and use them from a shareable page. - **Community Generators:** Browse and reuse generators created by the community, from RPG tools to story prompts and AI apps. - **Free to Use:** A large library of public generators is available to run in the browser without installing anything. **Strengths:** Completely free to use and publish; Simple list syntax that is easy to learn; Supports HTML, CSS and JavaScript for advanced tools; Huge library of community-made generators **Limitations:** Free without strong monetization may carry ads; Quality of user-made generators varies widely; Requires learning a specific list-based syntax to author generators; Some pages can be heavy on browser scripting [Profile (Markdown)](https://openaitools.app/tool/perchance-ai.md) ## Frequently Asked Questions ### How do Models.dev and Perchance compare in monthly traffic?
