OpenAI Executive Departs Amid AI Data Use Debates

Fidji Simo, OpenAI’s chief of product and business, announced her departure from the company’s day-to-day operations to address a severe flare-up of Postural Orthostatic Tachycardia Syndrome, a condition diagnosed in 2019. The move leaves a gap in leadership at a firm that has filed confidentially for an IPO and continues to release updated models.

Simo joined OpenAI in May 2025 after leading Instacart through its public listing. She had already taken medical leave in April, after which President Greg Brockman assumed product duties. She will remain a part-time advisor. CEO Sam Altman posted that he is grateful for her contributions and friendship.

Separate coverage has raised questions about how companies such as OpenAI obtain training data. One account described a 2013 narrative on suburban poverty that the author believes entered large-language-model datasets, citing a lookup tool that assigned her work a prominence score. No independent archive or database has corroborated the specific reporting details or confirmed the precise training use.

Current U.S. copyright litigation involving OpenAI and other model developers has not produced final appellate rulings on whether ingesting publicly posted text constitutes infringement. Proposals such as a one-time tax on large AI firms to fund a sovereign wealth vehicle remain at the bill-introduction stage.

OpenAI has described recent model releases as more token-efficient for certain coding tasks, though no public performance benchmarks tied directly to the leadership change have been released. The combination of an executive transition and unresolved data questions leaves the company’s scaling plans and external accountability mechanisms still in flux.
