✦ Confirmed Hatch is Meta’s internal name for Muse

The Name Meta
Still Builds
Muse Under.

Not a former name. Hatch is the codename Meta ships Muse under, in its own security post and in the live client at muse.ai. Every claim on this page is one curl away.

Not a leak, not a rumor. The footnote is in Meta’s own post, the symbols are in the shipped client, and both are still live.

Meta’s footnote

On 8 Sep 2026 Meta Research published “Security and safety for AI agents: our approach with Muse”. Its footnote, anchored #hatch-name-footnote, reads: “Hatch is our internal name for Muse in the codebase.” The post names the Hatch daemon, hatch-safety and hatch-authd: the agent harness in a systemd-nspawn cell, the prompt-injection classifier, and credential storage.

muse.ai, the live client

Pull the JavaScript bundles the public app loads and grep them. Eighteen unique Hatch symbols come back: React components, CSS custom properties and runtime flags. The brand is Muse. The code still answers to Hatch.

Launch day, from inside

The day Muse launched, Zhiqing Sun, lead agent research at Meta MSL TBD Lab and ex-OpenAI, quote-posted “why can’t you text ChatGPT from iMessage?” with a single word: Hatch. Three days later he called Muse Spark 1.3 “(Hatch)” in public.

Why $MUSE

Muse is the name you see. Hatch is the name that ships.

Meta shows the world Muse and builds it under Hatch. The token wears the brand; this site keeps the receipts on the codename underneath it.

Read before you buy

Community token.

Not affiliated with, endorsed by, or connected to Meta, Muse, or anyone quoted on this page. Nothing here is financial advice. Never trust an address that is not on this page.

007/ FAQ

Need Answers?

Everything you need to know before launch.

01/ What is Hatch?+

Hatch is Meta’s internal codename for Muse, its personal AI agent launched on 8 September 2026. Meta’s own research post says so in a footnote, and the muse.ai client still ships with Hatch-named components. $MUSE is a community token built around that receipt.

02/ Is this affiliated with Meta or Muse?+

No. This site and the token are a community project. They are not affiliated with, endorsed by, or connected to Meta, Muse, or any person quoted here. The quotes are public posts, linked to their source.

03/ Which chain is $MUSE on, and what is the contract?+

Robinhood Chain, chain id 4663. The contract address is not public yet: it will be posted in the Contract section at launch, and on our X. Until then, any address claiming to be $MUSE is fake.

04/ How do I verify the claims on this page?+

Run the three commands in the Verify section. They fetch Meta’s post and the muse.ai bundles and grep them. The numbers on this page are whatever those commands returned on the date shown next to them.

05/ Where do I buy?+

Nowhere yet. At launch, the buy link and the contract address will appear in the Contract section. Paste the address from this page into the token field, never one from a search result or a DM.

06/ Is any of this financial advice?+

No. This page documents a naming fact and lists a contract address. Do your own research and never invest what you cannot afford to lose.
