## Models.dev

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.

- **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

## Muse

Muse is a personal AI agent developed by Meta. Instead of answering questions and stopping there, Muse is designed to carry work through to completion: you hand it a goal or an ordinary task and it plans the steps, uses the tools it needs and reports back. Typical jobs include triaging and sorting email, booking reservations, shopping and saving money, keeping calendars in order, drafting fitness and health plans, and helping you stay on top of the relationships that matter to you.

Under the hood, every Muse user shares a dedicated Secure Virtual Machine with their agent — a persistent, isolated Linux computer running a full browser. This is what lets the agent do genuine work online rather than only talk about it. You can watch what it is doing and step in at any point, since the browser and machine belong to you. Storage, CPU and memory are sized for real workloads, not just demos.

You interact with Muse the way you already communicate: through the Muse app on mobile and desktop, or directly in WhatsApp, by text or voice. Control is explicit rather than implicit. Muse asks for approval before sensitive actions such as sending an email or making a purchase, and it keeps a complete audit trail of everything it has done and everything it is planning to do. It also connects to the apps you use daily — email, calendar, Instagram and more — with you deciding what it can see and what it may do, and it can even build a custom tool when a task needs one that does not exist yet. Muse is positioned for both individuals and small businesses.

**Pricing & Plans:** Muse is listed as contact-for-pricing on our directory; Meta has not published standard public plan pricing on the main product page, and access currently flows through logging in or creating an account. There is also a Muse for Business offering aimed at small businesses. Check the official site for the latest availability and any regional pricing.

- **Agentic task execution:** Give Muse a goal or an everyday chore and it plans and carries out the steps itself rather than only advising you.
- **Secure Virtual Machine:** Each user gets a persistent, isolated Linux computer in the cloud with a full browser, so the agent can do real work online while you retain control.
- **Human approval controls:** Muse requests your approval before important actions such as sending an email or making a purchase, keeping you in the loop.
- **Full audit trail:** A complete record of what the agent has already done and what it is planning next, so its behavior stays transparent.
- **Chat in app or WhatsApp:** Talk to your agent through the Muse mobile and desktop apps or directly inside WhatsApp, using text or voice mode.
- **App connections and custom tools:** Link everyday apps like email, calendar and Instagram, and let Muse build a bespoke tool when a task needs one that doesn't exist.

**Strengths:** Backed by Meta with a dedicated secure virtual machine per user; Approval prompts and a full audit trail keep agent actions accountable; Accessible from mobile, desktop and WhatsApp with text and voice; Can connect daily apps and build custom tools on demand

**Limitations:** Public plan pricing is not clearly published, making cost hard to estimate up front; Availability and feature rollout may vary by region; Agentic automation still benefits from careful review of approved actions
