OpenAI science lead leaves

Kevin Weil said April 17 was his last day at OpenAI as the company broke up the centralized OpenAI for Science group he had been leading. (x.com) Weil had joined OpenAI as chief product officer in 2024, and OpenAI later described him publicly as vice president of OpenAI for Science. Cisco said in May 2025 that Weil was OpenAI’s chief product officer, and OpenAI Forum event pages this month listed him as VP for OpenAI for Science. (openai.com) (newsroom.cisco.com) (forum.openai.com) OpenAI for Science is the company’s effort to build AI tools for researchers, from literature review to drafting papers and testing ideas faster. OpenAI’s science page says the program combines frontier models with research tools so scientists can explore more ideas and test hypotheses more quickly. (openai.com) One of those tools is Prism, a browser-based LaTeX writing workspace OpenAI introduced on January 27, 2026. OpenAI said Prism integrates GPT-5.2 directly into scientific writing, citations, equations, and collaboration, and the product page now says it also integrates ChatGPT and Codex. (openai.com 1) (openai.com 2) Weil said the science work will continue in a more distributed form instead of through one standalone team. WIRED reported that the science application he led was being folded into Codex, OpenAI’s coding product, as part of the reorganization. (x.com) (wired.com) The shift lands after OpenAI spent the past several months publicly tying AI to scientific research. In December 2025, OpenAI announced a collaboration with the U.S. Department of Energy and said Weil joined a White House Genesis Mission event the same day. (openai.com) OpenAI also used its science program to showcase research results this year. Its science page highlights a February 2026 post saying GPT-5.2 helped derive a new theoretical-physics result, with Kevin Weil listed as an author on behalf of OpenAI. (openai.com 1) (openai.com 2) Weil’s exit was part of a broader round of departures disclosed the same week. CNBC reported on April 17 that multiple OpenAI executives were leaving, and Bloomberg separately reported that Weil and Sora leader Bill Peebles had both stepped down. (cnbc.com) (bloomberg.com) For now, the science brand remains live on OpenAI’s site, but the reporting and Weil’s own post point to a different structure behind it. The work he helped launch is staying inside OpenAI, just no longer under a single dedicated leader. (openai.com) (x.com) (wired.com)
