As a fan of @Muse , George Orwell, open weights models and the Macintosh, this made me smile. Also check out Muse Spark Open, it's legit.

🐐 alert!
Really enjoyed speaking with @clairevo about the design of @Muse! We discuss a bunch of the little design decisions we made along the way, along with a few of my workflows: youtube.com/watch?v=4TOLm1g-…

Muse Wonder will soon power experiences in @Muse , and rolled out first to subscribers earlier today. I’ve been using it in my own Muse for a little while and appreciate how this model works harder and draws on memory more precisely with Active Focus and Active Memory.
MUSE WONDER 🍉 this model was developed to power personal agents. three highlights: - ACTIVE MEMORY: best memory across days/weeks/months - ACTIVE FOCUS: gets your tasks done - DOMAIN EXPERTISE: sota in finance & legal, strong in health

Today we’re previewing our work to build an open standard @Meta (@muse and Meta Business Agent) and Sierra are developing along with industry partners at Genesys, NiCE, Decagon, Rocket, Shopify, Stripe, and Walmart that defines how personal agents interact with businesses. What motivates this work is making things even better. More frictionless for people using Muse, and better for the businesses serving our shared customers. Excited to build this together.

My personal favorite Muse gadget hack so far - an ambient eInk display that sits above my keyboard where my @Muse pushes useful, fun or interesting content throughout the day.

We're also making a gadget we built available to all Muse subscribers. The Muse Home Link lets Muse connect to your home Wi-Fi to control your smart home devices among other things.

Excited to open source the Muse Gadgets SDK today! You can connect your DIY electronics like ESP32 boards and Raspberry Pi to Muse. Build an e-ink morning briefing, a push-to-talk pocket device, a sysadmin for your homelab, and much more. Details at gadgets.muse.ai
🚨 side project alert 🚨 Announcing Muse Gadgets, an open source ESP32 firmware and Linux sdk so that you can make hardware devices that work with Muse. Grab an API token from gadgets.muse.ai and point your favorite coding agent at the github repo to build your own peripherals for Muse.

Replying to @MattRobbt
Thanks Matt for walking through this with us. Glad that we were able to confirm together that there was no breach of privacy controls. We've also fixed the '00' price display issue based on your report. We take reports like this seriously and appreciate your feedback on how we can make things clearer in future too. We appreciate the opportunity to learn from your experience with Muse and keep making it better for everyone!

David from the Muse team here. I responded to Matt on Threads and sent him a couple of DMs offering to help and look into what happened. In the past, when we’ve worked with users to investigate similar reports, we’ve consistently learned that Muse was following direct instructions and correctly asked for permission. Would love to help and figure out what’s going on here!
Deleted Muse after seeing this post on Threads about how it told some Facebook Marketplace sellers the guy’s address and they showed up at his door Dangerous and creepy This would have been 1000x worse if the person was a woman

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.

I love cooking, so being able to talk to my Muse to go from recipe idea -> shopping list -> ingredients at my door has my mouth watering already!
Instacart is coming to @Muse! Soon, you can connect Instacart, say “Taco Tuesday,” and turn the idea into a cart from your favorite store. Then check out and get groceries delivered to your door. Same Instacart grocery experience, new way to get started. tr.ee/6xWsKG

Here at Expedia, we love planning trips. Soon, your personal AI agent will too. We're joining @Muse: tell it where you're headed and it can work with Expedia to sort your hotels, and everything in between.
