Breaking: Weng Li Leaves Thinking Machines

AI researcher Lilian Weng has left Thinking Machines after about 20 months at the company.

She said health issues and the demands of an intense workload made it difficult to continue as a cofounder.

Weng said she plans to remain in AI, but wants a role with more predictability and clearer boundaries.

Her departure has raised fresh questions about talent turnover and internal stability at the startup.
