Meta's Muse Agent Gives Users a Full Ubuntu Cloud Computer
Meta says every Muse user gets a Linux instance with its own root filesystem, while a separate Sentinel process watches sensitive actions.
In short
Meta gives every user of its Muse AI agent a free cloud computer running Ubuntu Linux, where they can install software, compile code and browse the web.
At a glance
- Every Muse user gets a free, full cloud computer with a complete Ubuntu Linux image.
- The Runtime Cell carries its own root filesystem, separated from the host machine.
- A separate Sentinel process monitors sensitive actions outside the Runtime Cell.
- Passwords and credentials are kept outside the Runtime Cell.
- Muse passed 500,000 users in its first week and reached No. 1 on the Apple App Store.
Sign up for Meta's Muse agent and you also get a machine: a free cloud computer running a complete Ubuntu Linux image, ready for installing software, writing and compiling code, and browsing the web. The technical account comes from David Singleton, VP of engineering at Meta Superintelligence Labs and formerly CTO of Stripe.
Where the agent actually works
Meta calls the workspace the Runtime Cell. Activity inside it is unrestricted, and the cell ships with its own root filesystem, walled off from the host machine. Poking around in there does not lead to Meta's own infrastructure or to any other user's data, according to the company's description.
The parts kept out of reach
Anything sensitive deliberately lives outside the cell. A dedicated process called Sentinel watches those actions, and passwords and credentials sit beyond the workspace. Meta presents the split, branded Muse Secure VM, as a defense against prompt injection.
How well that holds up under real attack is not something these sources establish. They relay the company's own architecture claims rather than an outside audit.
An agent you can read
Users can inspect every file, Meta says, from Debian system files to the Muse binaries themselves. A file explorer lives in the Library tab and behaves like the classic desktop kind. The markdown notes Muse writes while reasoning through a task are readable too, and a full export sits under Settings, Data controls, Download your agent data.
Demand in week one
Muse drew more than 500,000 users in its first week and hit No. 1 on the Apple App Store. Meta Connect 2026 added real-time video chats, dedicated email addresses for the agent, and control of a Mac app.
What is still unverified
Neither source gives numbers for how long an instance survives or what compute, storage or runtime caps apply. Both are the same publisher in two language editions, and both rest on Singleton's posts on X, which were not checked separately here. No independent confirmation of the security architecture is available at this point.
FAQ
What is the Runtime Cell in Muse?
It is the workspace where the user and the agent act without restrictions. It has its own root filesystem and is separated from the host machine; sensitive actions run outside it and are monitored by the Sentinel process.
Is Meta's Muse cloud computer free?
Yes, the Ubuntu Linux machine comes with Muse at no extra cost according to the available reports. The sources give no figures for runtime, storage or compute limits.
How do I download my Muse agent data?
Go to Settings, Data controls, Download your agent data. You can also open a file explorer in the Library tab, which shows the instance's files including the Debian system files.
