How Meta built safety into Muse

Meta's engineering write-up on Muse security: isolated VMs, a separate Sentinel permission authority, credential surrogation and layered prompt-injection defenses, with bug bounties up to $300,000.

The post details systemd-nspawn runtime cells mapped to unprivileged host users, Sentinel as sole gatekeeper for connector actions and network egress, and ensemble classifiers plus human approvals against prompt injection. It lists a $130,000 bounty for a successful single-user prompt injection and a planned confidential VM mode.

    Muse and the new fight for brand discovery

    DesignRush argued Muse inserts itself into product discovery and ranks on structured data like specs and reviews rather than ad spend, and told brands to map the agent shopping journey, measure agent referrals separately, and audit who can access their product data.

    Medical bills audited line by line, $4,000 saved★

    Got Muse logged in to my medical provider’s portal, he pulled the itemized bills, and questioned every line. So far he’s found several times I’d been double billed, asked for some discounts and has saved me over $4,000. If your moat is bureaucracy, you’re cooked.

    Plumbing company run by a Muse agent★

    I still can’t believe I can run my plumbing company with an agent so easily. I send this message to my Muse agent while in bed at 6am. And it: updates my job board, texts customer, updates office manager who arrives at 8am in slack Notifies technician
