Kevin Weil and Bill Peebles exit OpenAI as company continues to shed ‘side quests’
Kevin Weil and Bill Peebles are leaving OpenAI as the company shuts down Sora and folds its science team, signaling a sharp pivot away from consumer moonshots toward enterprise AI.
OpenAI is losing two of the architects of its most ambitious moonshots. Kevin Weil, who led the company’s science research initiative, and Bill Peebles, the researcher behind AI video tool Sora, both announced their departures on Friday. The exits come as OpenAI consolidates around enterprise AI and its forthcoming “superapp .”
The departures follow OpenAI’s decision to cut back on “ side quests ,” including customer-facing bets like Sora and OpenAI for Science. Sora, which was losing an estimated $1 million per day in compute costs, was shut down last month .
OpenAI for Science was the internal research group behind Prism , an AI-powered platform that promised to accelerate scientific discovery. It’s being absorbed into “other research teams,” according to Weil’s social media post announcing the news.
“It’s been a mind-expanding two years, from Chief Product Officer to joining the research team and starting OpenAI for Science,” Weil wrote. “Accelerating science will be one of the most stunningly positive outcomes of our push to AGI.”
The team had a short and bumpy road after its formal announcement in October 2025. Weil deleted a tweet claiming GPT-5 had solved 10 previously unsolved Erdős mathematical problems, but that claim fell apart immediately when the mathematician who runs the website erdosproblems.com called it out.
Weil’s departure comes a day after his team released GPT-Rosalind , a new model to accelerate life sciences research and drug discovery.
In a social media post announcing his departure, Peebles credited Sora with igniting a “huge amount of investment in video across the industry,” and argued that the kind of research that produced the video tool requires space away from the company’s mainline roadmap.
“Cultivating entropy is the only way for a research lab to thrive long-term,” he wrote.
OpenAI is also losing Srinivas Narayanan, its chief technology officer of enterprise applications, Wired reports . Narayanan reportedly announced the news internally that he was leaving to spend more time with family.

Editorial analysis
The departure of Kevin Weil and Bill Peebles from OpenAI marks a significant shift in the company's strategy, moving away from consumer-oriented projects and focusing more on AI solutions for the corporate market. This transition could have profound implications for the tech sector in Brazil, where the adoption of AI in business environments is still in its early stages. The trend of prioritizing practical and scalable AI applications may inspire Brazilian startups to reassess their approaches and seek solutions that directly address market needs.
Moreover, the decision to shut down initiatives like Sora and OpenAI for Science suggests increasing pressure for tech companies to demonstrate tangible financial results. This could reflect the current market dynamics, where investors are becoming more demanding regarding return on investment. For the startup ecosystem in Brazil, this may mean a shift in focus, where more experimental and long-term projects could be sidelined in favor of immediate and profitable solutions.
What to watch for from this movement is how OpenAI will develop its "superapp" and what functionalities it will offer. The integration of different AI capabilities into a single platform could open new opportunities for Brazilian companies looking to adopt cutting-edge technologies. Additionally, the departure of Srinivas Narayanan, CTO of enterprise applications, may indicate an internal restructuring that could impact how OpenAI engages with its partners and clients in Brazil and Latin America.
Finally, the emphasis on research and development of AI geared towards the corporate sector could lead to increased investment in technology infrastructure in Brazil, as companies seek to adapt to this new reality. Collaboration between tech companies and academic institutions could be a fruitful path to accelerate innovation and AI adoption in the country.
