Kevin Weil and Sora lead Bill Peebles leave OpenAI as it folds OpenAI for Science into other teams and sheds 'side quests'
On April 17, 2026 Kevin Weil (former chief product officer, then head of OpenAI for Science) and Bill Peebles (head of Sora) announced they were leaving OpenAI, along with enterprise-applications CTO Srinivas Narayanan. OpenAI was folding the standalone science unit into other research teams and cutting experimental projects to focus on enterprise AI, a month after it announced Sora's shutdown.
Key facts
- Departures announced Friday April 17, 2026: Kevin Weil, Bill Peebles and Srinivas Narayanan, CTO for enterprise applications (TechCrunch)
- OpenAI for Science, led by Weil, is absorbed into other research teams rather than continuing as a standalone unit
- Weil's team had just released GPT-Rosalind, a life-sciences research model (April 2026)
- Weil called his time at OpenAI 'mind-expanding'; Peebles: 'Cultivating entropy is the only way for a research lab to thrive', arguing that breakthrough research like Sora needs distance from the main business
- Context: Sora was announced to shut down on March 24 and reportedly lost ~$1M a day in compute; TechCrunch framed the exits as OpenAI 'continues to shed side quests'
What happened
In one day OpenAI lost the leader of its science push and the creator of Sora. The reorganisation fits the company's 2026 strategy: fewer consumer experiments and more focus on enterprise agents and core models before an IPO. AI-for-science work continues inside the research organisation (e.g. GPT-6 Astra's maths results), but no longer as a separate unit.
Why it matters
It marks the end of two of OpenAI's most visible bets of 2024–25, consumer video and a standalone science division. It is part of a wave of senior departures in 2026 (Fidji Simo in July; safety staff in the autumn).
