Muse Updates: Every Meta Muse Change, Tracked
A dated changelog for Muse, Meta's personal AI agent: launches, model releases, region changes, pricing news and security updates — verified and updated continuously.
Muse changes fast, and Meta scatters its announcements across the Newsroom, research blogs, developer docs and security pages. This is the merged, dated timeline — every entry cites its source, and anything unconfirmed stays out until it's real. Bookmark this page or follow the RSS feed; it's the freshest page on this site.
The timeline

| 2026-09-08 | Security documentation published | security.muse.ai details Sentinel as sole egress authority, sanitized training trajectories, bug bounty up to $300,000 (incl. $130,000 prompt-injection) | Security researchers, privacy-conscious users | security.muse.ai via press |
| 2026-09-08–09 | Pricing reported, not yet official | Press (TechCrunch/CNBC, quoting Meta) report Power $20/mo and Maximum $100/mo tiers plus a required payment card and usage meter; Meta has published no plan pages | Prospective subscribers | TechCrunch |

What we're watching next
- Confidential VM shipping — the announced end-state where even Meta can't read your VM data (currently policy-based, per Wired). This would be the single biggest privacy upgrade on this list. See what's confirmed and what's open.
- Official pricing pages — which would replace press-reported numbers across our pricing and limits pages.
- New countries — each one updates the availability tracker the same day.
- WhatsApp setup documentation — Meta hasn't published official steps yet; see the current state in our WhatsApp guide.
- API developments — any move from models-only access toward agent-level APIs; see Muse AI API.
How this page works
Newest entries go on top with their date; "who is affected" tells you whether it's a user-facing, developer-facing or security change. When an entry is superseded (a price confirmed, a country launched), the old entry stays for the record and the affected guide pages get updated the same day. For the vocabulary these updates introduce, see our new-terms glossary.

Frequently Asked Questions
How often is this Muse changelog updated?
Whenever something verifiable changes — a model release, a new country, official pricing, a security disclosure — with the date and an official or attributed source on every entry. Rumors and unconfirmed leaks don't get entries; they get watched until they're real.
What was the biggest recent Muse update?
The agent's own launch on September 8, 2026 in the US — the first time an AI agent shipped for general consumers with its own secure VM, a guardrail agent (Sentinel) and one-tap approvals across email, payments and shopping.
Where do I get official Muse news?
Meta's Newsroom announcement and Meta's research blog (research.meta.ai) are the primary sources; the security page (security.muse.ai) covers vulnerability disclosures. This page exists because those sources don't give you one merged, dated timeline.
