Machine Heart reports that Lilian Weng has left Thinking Machines Lab just as the company launched Inkling.
- Weng says she had been ill repeatedly for the past seven months and could no longer sustain startup pace and pressure.
- She says she has been involved for about 20 months since the company’s early formation.
- In her farewell note, she says she still loves AI, but needs a more predictable environment and more clearly bounded work.
- Mira Murati replied that the team will miss her, thanked her for her contributions, and said she made the right decision by prioritizing her health.
- The article frames the exit as a reminder that startup success often comes with intense personal cost, even around high-profile model launches.
