Meta AI Updates: September 26, 2026

1. Every Muse User Gets a Full Ubuntu VM With a Sentinel Watching From Outside

Meta confirmed that each Muse user gets a personal cloud computer running Ubuntu Linux where they can install software, compile code, and browse the web, according to David Singleton, VP of Engineering at Meta Superintelligence Labs. The design places the user workspace in a “Runtime Cell” inside a Muse Secure VM, with a separate “Sentinel” process outside it monitoring sensitive actions and keeping credentials out of the user’s environment. Users can browse the entire filesystem, including system binaries, and export their data from Settings. Source

2. Horizon Create and Horizon Studio Turn Prompts Into Multiplayer Mobile Games

Meta introduced Horizon Create, a phone app, and Horizon Studio, a browser editor, both built on the agentic creation features of the Meta Horizon Engine to generate complete 2D or 3D games from natural-language prompts, including progression, difficulty balancing, art direction, and multiplayer. Projects move between the two tools, and Studio adds visual controls for scene layout, asset swaps, and script parameters. Published games get native distribution in Facebook, Instagram, and Horizon, where a feed clip can drop a viewer into a multiplayer session without installing anything. Early access is rolling out gradually through a waitlist. Source

3. Meta Is Recruiting AI Power Users for Muse Early Access

Meta opened an early access program for the Muse features announced at Connect, including video chat with an avatar, Mac computer use, more shopping connectors, and wake-word activation on AI glasses. Users join by asking Muse itself to sign them up, or through a link Meta shared on X. Rather than random beta selection, Meta says it is targeting people who already use several AI apps and can compare Muse against competitors. Source
