Kevin Weil, OpenAI’s former chief product officer who was recently tapped to build a new AI workspace for scientists, Prism, is leaving the company, WIRED has confirmed. Weil was previously an early executive leading product at Instagram.

“Today is my last day at OpenAI, as OpenAI for Science is being decentralized into other research teams,” Weil said in a social media post on Friday, shortly after WIRED reported his departure. “It’s been a mind-expanding two years, from Chief Product Officer to joining the research team and starting OpenAI for Science.”

Weil did not immediately respond to a request for comment from WIRED.

OpenAI is also sunsetting Prism, which the company launched as a web app in January to give scientists a better way to work with AI. The company is folding the roughly 10-person team behind it under OpenAI’s head of Codex, Thibault Sottiaux, and aims to incorporate Prism’s capabilities into its desktop Codex app. An OpenAI spokesperson confirmed the changes and tells WIRED this is part of the company’s effort to unify its business and product strategy. OpenAI has broader ambitions to turn Codex, its AI coding application, into an “everything app.”

Weil, who joined OpenAI in June 2024, announced last September that he would be starting a new initiative inside of the company called OpenAI for Science. Now, OpenAI is dispersing those employees throughout the company’s product, research, and infrastructure teams. An OpenAI spokesperson reiterated the company’s commitment to accelerating scientific discovery and says it’s one of the clearest ways AI can benefit humanity. Earlier on Friday, the company announced a new series of AI models—GPT-Rosalind—built to help life sciences researchers work faster.

OpenAI is trying to refocus the company around a few key areas, such as enterprise offerings and coding, as the company faces increasing pressure from rivals like Anthropic and gears up to file for an IPO later this year. In March, OpenAI’s CEO of AGI deployment, Fidji Simo, told staff that the company needs to simplify its product offerings. The push to divert resources to more consequential efforts resulted in OpenAI discontinuing its Sora video-generation app.

Unrelated to Weil’s news, two other executives announced on Friday that they are departing OpenAI. OpenAI’s chief technology officer of enterprise applications, Srinivas Narayanan, announced internally that he is leaving the company to spend time with his family. Narayanan had joined OpenAI as the company’s VP of engineering. And Bill Peebles, head of Sora, posted on X that he was done at OpenAI as well.

The exits of Weil, Peebles, and Narayanan are just the latest in a series of executive shake-ups at OpenAI. The company recently announced a major reorganization of its executive team as Simo took a medical leave to focus on her health. In the same announcement, OpenAI said cofounder and president Greg Brockman would oversee the company’s products in the interim, and the company’s chief marketing officer, Kate Rouch, would take a leave of absence due to medical issues. Chief operating officer Brad Lightcap transitioned to a “special projects” role as part of the restructuring as well.

OpenAI CEO Sam Altman seemed to acknowledge the various upheavals in a recent blog post. “I am also very aware that OpenAI is now a major platform, not a scrappy startup, and we need to operate in a more predictable way now,” he wrote. “It has been an extremely intense, chaotic, and high-pressure few years.”

PwC research found that Irish companies are somewhat lagging behind their global peers where AI implementation and benefits are concerned.

Professional services company PwC has released data exploring how organisational leaders are navigating AI gains across a range of areas, such as growth, revenue, investment, workflows, autonomous decisions, reinventing business models and governance, and analysing where the AI leaders are driving results.

PwC collected data for a survey from 1,217 senior executives around the world, including from Ireland, at a director level or above, at companies across 25 sectors and multiple regions worldwide. 

From that information, PwC found that nearly three-quarters (74pc) of AI’s economic gains are being utilised by only 20pc of companies. According to the findings, this is indicative of a “stark and widening divide between a small group of AI leaders and the majority of businesses still stuck in pilot mode”.

Commenting on the report, David Lee, the chief technology leader for PwC Ireland, said, “Many companies are busy rolling out AI pilots, but only a minority are converting that activity into measurable financial returns.

“The leaders stand out because they point AI at growth, not just cost reduction, and back that ambition with the foundations that make AI scalable and reliable.”

Is Ireland keeping pace?

Ireland specifically was found to be falling behind its global peers when it comes to AI implementation and benefits.

Lee said: “Based on our previous studies, Irish companies do somewhat lag global peers where AI implementation and benefits are concerned.”

He added that “PwC’s 2026 Irish CEO survey reveals fewer Irish CEOs (8pc) report AI application across a range of business areas compared to global counterparts (18pc), including demand generation, products, services, experiences and strategic direction-setting”.

He noted: “Some of the benefits from AI are also taking longer to come through compared to global peers, with Irish organisations seeing the opportunities from AI, but are not yet grasping the transformative powers.

“17pc of Irish CEOs say that AI has delivered increased revenues in the past 12 months, behind global peers (29pc). Nearly a quarter (23pc) say that AI has delivered cost reductions in the past 12 months, also behind global peers (26pc).”

The companies that are leading were found to be roughly two to three times more likely to use AI to identify and pursue growth opportunities or reinvent their business model. They are also twice as likely to redesign workflows to incorporate AI rather than simply adding new AI tools.

They are nearly three times more likely to have increased the number of decisions made without human intervention and were shown to be going further in relation to AI governance. Within high-performing companies, trust at scale models were found to be effective. 

The report said, “AI leaders are more likely than other companies to have mechanisms such as a responsible AI framework (1.7 times as likely as other companies) and a cross-functional AI governance board (1.5 times). As a result of their efforts, their employees are twice as likely to trust AI outputs.”

Time for a change

PwC’s report suggested that a failure to shift the current approach to the implementation of artificial intelligence by the majority would likely widen the performance gap between AI leaders and “laggards”, particularly as leading organisations continue to learn, grow, and automate safely and speedily.  

Commenting on the results of the research, Martin Duffy, the head of AI and emerging technologies at PwC Ireland, said: “AI return on investment comes down to execution discipline – clear metrics, fast stop-or-scale decisions and designs built for reuse. Value shows up when AI is embedded in everyday workflows, not isolated pilots.”

Grinex, a US-sanctioned cryptocurrency exchange registered in Kyrgyzstan, said it’s halting operations after experiencing a $13 million heist carried out by “western special services” hackers.

Researchers from TRM, which has confirmed the theft, put the value of stolen assets at $15 million after discovering roughly 70 drained addresses, about 16 more than Grinex reported. Neither TRM nor fellow blockchain research firm Elliptic has said how the attackers slipped past Grinex’s defenses. Grinex said it has been under almost constant attack attempts since incorporating 16 months ago. The latest attacks, it said, targeted Russian users of the exchange.

Damaging “Russia’s financial sovereignty”

“The digital footprints and nature of the attack indicate an unprecedented level of resources and technology available exclusively to the structures of unfriendly states,” Grinex said. “According to preliminary data, the attack was coordinated with the aim of causing direct damage to Russia’s financial sovereignty.”

“Due to the attack, the Grinex exchange is forced to suspend operations,” Grinex continued. “All available information has been transferred to law enforcement agencies. An application has been submitted to the location of the infrastructure to initiate a criminal case.”

TRM said that TokenSpot, a second Kyrgyzstan-based exchange, was also breached. Two of the exchange’s addresses sent funds to the same consolidation address used by the affected Grinex-linked wallets. What’s more, both exchanges became inoperable on Wednesday, suggesting they were hit by the same attacker.

TRM said TokenSpot was a front for Grinex, which the US Treasury Department sanctioned last year. The department’s Office of Foreign Assets Control said that Grinex, in turn, was a rebrand of Garantex, an exchange it had sanctioned in 2022. The department said then that Ganantex had “directly facilitated notorious ransomware actors and other cybercriminals by processing over $100 million in transactions linked to illicit activities since 2019.” Last year’s sanctions against Grinex came a few months after TRM said that the exchange was likely a front for Ganantex.

• The dual agent AI system autonomously solved Anderson’s conjecture from 2014
• Rethlas explores problem-solving strategies like a human mathematician would
• Archon transforms potential proofs into projects for the Lean 4 verifier

A research team led by Peking University developed a dual-agent AI system capable of solving advanced mathematical problems while also verifying its own results.

The system resolved a conjecture proposed in 2014 by Dan Anderson, completing the process within 80 hours of runtime.
