💼 AI Researcher Andrew Tulloch Leaves Meta

According to an exclusive Semafor investigation, Tulloch, who worked at the TBD lab (superintelligence division, head — Alexandr Wang), is leaving the company. The reason for his departure and his new plans have not been announced; in 2025, he moved to Meta from Thinking Machines Lab (Mira Murati).

🌍 Meta is losing one of the most expensive hires in the history of AI: a package of about $1.5 billion over 6 years according to Semafor, over $1 billion according to WSJ — the amounts are disputed. Semafor sees two scenarios: a top position at OpenAI, Anthropic, or Google, or his own startup.

👤 News of his departure came just days after the announcement of the AI assistant Muse (September 8): Meta's flagship superintelligence lab has already lost a key figure in the "talent war."
