Overview
- Reporting on September 10, 2026 says Andrew Tulloch quit Meta one day after the company released Muse, an agentic AI tool aimed at mainstream users.
- Meta confirmed the public launch of Muse but has not publicly confirmed Tulloch’s departure or provided a reason for it.
- Tulloch worked in Meta’s TBD lab inside the Superintelligence Labs and reported to Meta AI chief Alexandr Wang.
- A Wall Street Journal account that Tulloch was offered a possible $1.5 billion pay package is disputed by Meta’s spokesperson and it remains unknown what compensation he received at Meta.
- The episode underlines fast-moving hiring and retention pressures in AI and could prompt closer scrutiny of high-profile recruitment practices and researcher turnover at major labs.
