Muse is now available in the US on iOS, Android, web, and WhatsApp. Japan release timing is undecided.","whyItMatters":"Meta's Muse enters the AI agent space with a safety architecture that isolates each agent in its own VM and gates real-world actions through a permission agent, addressing the core risk of AI making purchases and sending messages.","webCardHtml":"\u003cp\u003eDuring the announcement, Meta demonstrated Muse planning a December trip to Japan, building an itinerary for Tokyo, Hakone, and Kyoto, booking a restaurant, and then finding a 5 km running course near the hotel to add to the user\u0026#39;s training plan. The agent also handled a stroller purchase, showing product comparisons and a final Allow confirmation before payment. Payments run through Stripe\u0026#39;s Link service, with disposable card numbers so the actual card number is never passed to the seller. Shop Pay and 1Password support are planned.\u003c/p\u003e","blueskyPost":"Meta's new Muse agent can email, book trips, and shop, but it runs in a per-user VM with a Sentinel permission agent that asks before any purchase.
