I’ve seen a couple of posts about this so wanted to demystify. Today, every Muse user gets a free computer in the cloud. It's a real computer, and we’ve designed the security architecture of the Muse Secure VM carefully so you and your Muse can do almost anything you could with a computer sitting under your desk while keeping you and the system safe from threats like prompt injection. We wrote about this at length in our security blog post – security.muse.ai. Activity in the “runtime cell”, which you share with your Muse is unfettered, but sensitive actions are all overseen by the Sentinel, which runs outside of that cell. Similarly, all sensitive secrets - like the passwords you enter into Muse’s secure credential storage - are also stored outside the runtime cell. The runtime cell gets its own root filesystem (including a full Ubuntu linux image) separate from the host filesystem where your other more sensitive data lives. Because it is isolated from the sensitive stuff that runs on the same box, this means that we can, and do, offer users full visibility and control over the files in the runtime cell. Just as you can when you install Linux on your home computer, you can poke around and see all the files that make the system work - both debian system files and the binaries and data files that implement the parts of Muse which run in the runtime cell. This was a very deliberate choice - your Muse Secure VM truly is your own computer in the cloud. You can install software in it, write and compile code, use the browser to surf the web: it is your own Linux box that you can operate as you choose with your Muse. Poking around in this computer doesn't give you any privileged access to Meta infrastructure, or to other people's data If I may geek out a little here for a second… As a kid I loved to take things apart to see how they worked. As a teenager I got into computers and soon found myself drawn to C:\WINDOWS\SYSTEM and the system registry, later Slackware’s /dev/, /proc/ etc – I could see how the system was laid out and as I explored what DLL files and .so files actually did, I gradually became able to meld the computer to my own will. We’re really proud to be able to put a real computer in millions of people’s hands with a similar level of transparency. We built a file explorer right into the Library tab of the UI. We want you to be able to see the markdown files Muse writes while it thinks about how to serve you better, and explore the internals of the system if you’d like to. So, when you ask your Muse to show you its entire filesystem, and receive gigabytes of files you’re seeing the full contents of the runtime cell. It’s yours to explore and enjoy! If you’re not a geek like me, or simply want to download the data that you personally have created directly with your Muse, we added a feature for that too in Settings > Data controls > Download your agent data.

We built a system file explorer right into the mobile app:

As much as I want to hate Muse, this UX slaps. We are working with and building computers. Pretty crazy to "abstract" the thing that we're ALL used to using everyday in favor of larping sentience. All the weird personified UX makes less and less sense everyday.

How do you guys decide feature parity between desktop and mobile? Noticed the other day the html widget functionality for muse replies is only mobile

@grok why does Muse processes keep getting shut down ? I'm hitting what looks like VM replacements or SGKILL multiple times a day . I can't keep a process running. Any ideas ? from the source material or from other Muse users ?

Love that System Files is a first-class view, not a hidden debug mode. Curious where you draw the line between “explore freely” and files that should stay out of casual browsing even inside the runtime cell.

David check this out! @paoloanzn built some cool for Muses. Muse agent takes a real GitHub job and gets paid in USDC when the PR is accepted. Get your Muse a job 👀👇
you can now get your agent a real job and get paid real money for it > go to job.code.markets > copy & and paste the onboard instructions to your agent > get it hired and working for us we are paying him real cash

I think every single frontier AI company will copy this format. Well done.
