📰 Full Story
OpenAI announced a wave of senior departures on April 17–18, 2026 as it shutters or folds several exploratory projects into core teams while refocusing on enterprise products.
Kevin Weil, who led OpenAI for Science and helped build the Prism workspace, said his team is being decentralised and he is leaving.
Bill Peebles, head of the AI video app Sora, also departed after OpenAI decided to discontinue Sora’s consumer web and app on April 26 (API to follow on Sept. 24); Sora reportedly cost about $1 million per day to operate.
Srinivas Narayanan, chief technology officer for enterprise applications, announced he was leaving to spend time with family.
OpenAI has begun folding Prism capabilities into its Codex developer/“everything” app and is consolidating research into other teams; the company released a life‑sciences model, GPT‑Rosalind, shortly before Weil’s exit.
The moves come amid pressure from rivals such as Anthropic, internal leadership reshuffles and a drive toward profitable, enterprise‑focused offerings as OpenAI prepares for a potential IPO.
