Andrew Tulloch, Meta’s star AI recruit, is leaving after less than a year

Andrew Tulloch, after 11 years at Meta and a period at OpenAI and co-founding Thinking Machines Lab, is joining Anthropic. Sources say Meta’s alleged $1.5 billion six-year compensation package for his return is contested. His move follows Meta’s launch of the Muse personal AI agent and occurs as Anthropic expands its high-salary hiring amid turnover at rival AI labs.
