Weng, who previously departed OpenAI alongside several colleagues to co-found a competing AI startup—a venture reportedly helmed by Mira Murati, OpenAI’s former CTO—has announced a significant career transition. In a recent statement, Weng revealed her decision to leave the startup after a month-long absence focused on her health, an period that preceded the release of Thinking Machines Lab’s initial model, Inkling. She articulated a desire to move away from "consistent stress and workload" in pursuit of "a scoped role in a more predictable place." Reports now indicate that Weng has already returned to OpenAI.
