Lilian Weng announced her departure from Thinking Machines Lab citing health stress, then rejoined OpenAI two days later, prompting advice on how employees should frame resignation statements.

After stating on X that ongoing stress at Thinking Machines Lab had exceeded her physical limits, co-founder Lilian Weng announced she was stepping down. Within 48 hours, OpenAI disclosed that she was re-joining the company to head a research acceleration team, a move that raised questions about the prudence of public resignation rationales.
