Two OpenAI executives depart amid leadership shakeup
OpenAI announced the departures of Kevin Weil and Bill Peebles on April 17, 2026, part of a broader pullback from experimental "side quests" as the company concentrates on enterprise AI and a forthcoming "superapp." Weil led the internal OpenAI for Science research initiative (after serving as Chief Product Officer); his team’s Prism work is being redistributed into other research teams. Peebles, the researcher behind the short-form AI video app Sora, left after Sora was shut down last month amid reportedly high compute costs. The article also reports the exit of Srinivas Narayanan, OpenAI’s chief technology officer for enterprise applications. Recent releases tied to these teams include GPT-Rosalind, a model for life‑sciences research. The moves signal OpenAI shifting resources away from costly consumer-facing experiments toward core product and enterprise priorities.
Leadership departures at OpenAI are notable because OpenAI is a major AI platform preparing for a potential IPO; executive turnover and product shutdowns (Sora) could affect product roadmaps, partnerships, and compute allocations relevant to the broader AI ecosystem.

OpenAI Shuts Down Sora and Video Models
OpenAI shut down Sora, its consumer AI video-generation app, roughly six months after launch. A Wall Street Journal investigation cited by TechCrunch reports Sora peaked at about 1,000,000 users before falling under 500,000, while costing OpenAI roughly $1,000,000 per day to operate because of expensive video-generation compute. Leadership concluded the app was diverting compute and engineering resources at a time when competitors — notably Anthropic and its Claude Code offering — were attracting talent and enterprise customers. CEO Sam Altman decided to discontinue Sora to free up compute and refocus the company. The shutdown also ended a planned partnership with Disney (reported as a roughly $1 billion commitment), whose deal collapsed after the closure was announced, with Disney reportedly told less than an hour before the public announcement.
OpenAI COO Brad Lightcap to Leave for New Venture
Brad Lightcap, one of OpenAI’s longest-serving executives, announced on X that he is leaving the AI lab after eight years to “start something new.” He joined in 2018, served four years as chief financial officer, was chief operating officer from 2022 until early 2026, and moved into a special-projects role in April before departing. OpenAI said chief revenue officer Denise Dresser will assume most of his responsibilities. Lightcap helped scale the go-to-market team from roughly 50 to more than 700 by mid-2025. His exit is the latest in a string of senior departures — including Fidji Simo, Bill Peebles, Kevin Weil and Srinivas Narayanan — as OpenAI prepares for a potential IPO and faces scrutiny over its valuation.
OpenAI ends Sora, refocuses on enterprise AI agents
OpenAI has announced it will discontinue Sora, its consumer-facing AI video application, signaling a strategic shift toward enterprise customers and so-called AI agents. The company said users will be informed later about the shutdown timeline and how to retrieve their work. The move follows internal direction to prioritize core initiatives amid rising costs and questions about business model sustainability despite nearly a billion global users of OpenAI services. CEO Sam Altman informed staff of the change; reports also say product-lead Fidji Simo had urged teams to avoid side projects and to push into autonomous AI agents. The cancellation affected a proposed, reported licensing arrangement with Disney that, according to some outlets, never resulted in the planned investment.
