Thinking Machines Fourth Co-Founder Sharon Wong Resigns Citing Health Issues

Sharon Wong departs Thinking Machines Lab, marking the fourth co-founder exit since inception. The departure occurs shortly after the launch of the Inkling model.

Woofun AI reports that Sharon Wong, a co-founder of Thinking Machines Lab, has resigned due to health concerns stemming from sustained pressure and workload over the past seven months. Wong took a month-long sick leave during the development of the Inkling model and stated she cannot accept partial responsibilities, seeking instead a research role with clearer duties and a stable pace.

This departure marks the fourth co-founder to leave the company since its founding, following Andrew Tulloch’s move to Meta and the returns of Barret Zoph and Luke Metz to OpenAI. The resignation follows the release of Inkling, the lab’s first open-weight model, approximately two weeks ago.
