Kevin Weil leaving OpenAI; Prism web app folded into Codex

What happened

It has been reported that Kevin Weil, OpenAI’s former chief product officer who was tapped to build the company’s “OpenAI for Science” initiative, is leaving OpenAI. WIRED reports Weil posted that “today is my last day at OpenAI,” and that the OpenAI for Science team is being decentralized across other research and product groups. It’s a conspicuous exit — Weil joined in June 2024 after a high-profile stint at Instagram and had been leading Prism, a web app launched in January to give scientists an AI-native workspace.

Prism shuttered, work folded into Codex

OpenAI confirmed it is sunsetting Prism and folding the roughly 10-person team into Codex under Thibault Sottiaux, with plans to bake Prism’s features into Codex’s desktop app. The company says this is part of a broader effort to simplify product strategy and unify offerings; OpenAI has openly discussed turning Codex, its coding AI, into an “everything app.” A spokesperson framed the move as continuing the firm’s focus on accelerating scientific discovery — but the practical result is Prism’s standalone experiment will vanish.

Why this matters

Why should anyone care? Because this is more than one executive leaving. It’s a sign of a company tightly re-prioritizing as rivals heat up and an IPO looms. OpenAI has already been trimming projects — remember Sora, the video generator? — and this shuffle follows other recent exits and medical leaves among senior leaders. For scientists who had pinned hopes on a dedicated research workspace, the dispersal of the OpenAI for Science team is the emotional heart of the story: a small, focused project absorbed into a much larger product vision.

The broader shuffle

Expect more consolidation. OpenAI says it will redeploy people into product, research, and infrastructure teams; whether that accelerates or dilutes the work depends on execution. In the meantime, Prism users will see their standalone tool shuttered, and the industry will be watching whether Codex can genuinely become that all-in-one platform everyone keeps talking about.
