Andrew Tulloch, co-founder of Thinking Machines Lab, has left the AI startup to join Meta Platforms, the Wall Street Journal reported.

Tulloch previously worked at OpenAI and Facebook’s AI Research Group.

Tulloch's departure comes after Thinking Machines Labs, co-founded by former OpenAI CTO Mira Murati, unveiled its first product, Tinker recently, ending months of speculation on what the startup was working on.

Earlier in July, Thinking Machines Lab had also attracted a whopping $2 billion in a seed funding round led by Andreessen Horowitz at a $12 billion valuation even before making the product public.

Notably, Meta, which had been poaching AI talent from rivals since June to put together its superintelligence team, had also attempted to lure a handful of senior researchers from Thinking Machines Lab earlier in July. However, all the employees had rejected the offer then, the Wired had reported.

Interestingly, one senior researcher was also offered an eye popping over $1 billion package over several years.
