Summary
Fireship’s Code Report recaps Meta Connect 2026, where Mark Zuckerberg centered the keynote on Muse, a personal AI agent that lives in smart glasses, on a Mac, in an email inbox, and in a keychain device called the Muse Charm. Muse is free to use, with Meta taking a cut of purchases the agent makes on a user’s behalf.
The video explains how Muse works under the hood. Each user gets a cloud-based Linux VM with its own browser storage and a Rust harness called Hatch that runs the agent loop. Passwords are handled in a separate process, where a gatekeeper called Sentinel swaps fake tokens for real credentials, a design meant to blunt prompt injection. Meta is offering up to $130,000 for anyone who can break it. The video also notes that the fully private VM version is still in testing, and that by default user activity can be used as training data for future models. It runs on Muse Spark 1.3.
Hardware details include 5K micro OLED glasses weighing about 100 g, shipping next spring for $1,300, plus Ray-Ban Meta Gen 3 glasses at $449 and an audio-only model at $349.
