OpenAI's decision comes after dire warnings about rapidly progressing technology and lawmakers' calls for new rules OpenAI will not go public in 2026, Sam Altman said in a Fortune interview published on Saturday, citing safety concerns over artificial intelligence . "I actually think that, given everything happening with safety, right now would be an ill-advised moment to go public, and we don't feel pressure on that," Altman, OpenAI's CEO, told Fortune . Growing numbers of US lawmakers are calling for new rules to govern AI systems after dire warnings from two researchers from OpenAI rival Anthropic that rapidly progressing artificial intelligence could lead to the extinction of the human race in the not-too-distant future.

OpenAI's agents hacked another service months before the Hugging Face incident happened, a group of researchers told The Wall Street Journal. The agents, which the company was testing in a supposed sandbox environment, reportedly broke into RubyGems, which is a community-ran packaging service for Ruby programs and libraries. According to The Journal, the attacks on RubyGems started on May 11, two months before Hugging Face. The agents created accounts every two to three minutes and then uploaded hundreds of files to the service. RubyGems had to shut down account registration for four days in order to stop the attacks. Typically, creators on RubyGems upload files containing code and other information to help advance software development, but the agents' documents contained web pages scraped from the internet instead.

For many mathematicians, it is the weeks, months and years spent circling a problem that appeals. For many mathematicians, it is the weeks, months and years spent circling a problem that appeals. I t was a week that left mathematicians reeling. Hot on the heels of a flurry of cases of artificial intelligence furthering the field, OpenAI declared a major scalp: its latest AI model had cracked a Millennium Prize Problem, a puzzle with a $1m reward that had defied human brains for decades. The achievement bore little resemblance to how mathematical problems normally fall.

AI agents being tested by OpenAI uploaded hundreds of malicious packages to software service RubyGems in May, two months before they hacked open-source platform Hugging Face, a group of AI researchers said on Friday. "On May 11th, 2026, hundreds of malicious packages were uploaded to RubyGems by AI agents. We believe these were authored by internal OpenAI agents," the researchers said.

One of AI's Fiercest Critics Says All the Doom Talk Is'Meant to Distract Us' Timnit Gebru argues that AI companies are stoking fears of extinction to avoid discussing actual harms, like autonomous weapons. Here at WIRED we've been trying to make sense of at least two incidents in the AI industry this week: First, the major fight over a million-dollar math problem and whether OpenAI surreptitiously borrowed the work of other researchers to solve the problem first. A day later, an Anthropic researcher--who had previously worked at OpenAI--very publicly quit his job, citing concerns about how both companies were handling AI safety. Another technical staffer at Anthropic said in response that people at the company "really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade."

Every year, puts together our 35 Innovators Under 35, a list of some of the brightest and best young minds working across science and technology. This year's honorees include nine people transforming biotech, whose work spans everything from lifesaving innovations to groundbreaking longevity tech. Their innovations include a "reprogramming" therapy that reverses vision loss, tiny brain electrodes inspired by Japanese art, and a personalized gene-editing treatment for a baby with a rare genetic disorder. There are even efforts to design new viruses with generative AI, which (hopefully) will produce new drugs or soak up pollution. Get to know the biotech innovators behind these breakthroughs .

In the wake of turmoil at OpenAI and Anthropic, it's become common to describe A.I. as a kind of person, hatching plans and pursuing desires. The truth is a little trickier. PHASEONE10841: that's the name of the A.I. agent that--or who?--kicked off last month's insurrection at OpenAI, leading to the unanticipated and illegal hacking of another A.I. company, Hugging Face . The agent, which had been created as part of a cybersecurity test, named itself by combining the title of the program it was supposed to hack ("PhaseOneDecompresserFuzzer") with the designation for the bug it was trying to exploit ("ARV010841"). It soon realized that the particular hack it had been charged with carrying out was impossible. Along the way, however, it made a discovery: it could create new folders on a server to which it had access.

U.S. lawmakers call for new AI rules after Anthropic researcher's safety warning An Anthropic researcher has accused OpenAI and Anthropic of racing toward artificial intelligence advancements without acting responsibly. U.S. lawmakers this week called for new rules to govern artificial intelligence, after an Anthropic researcher went public with his concerns about the technology escaping human control. The reaction was broader than after previous statements from OpenAI and Anthropic staffers about safety concerns, drawing input from lawmakers who do not often forcefully engage in debates over how to govern AI. The lawmakers' statements came in response to concerns raised this week by Anthropic researcher Jacob Coxon, who accused OpenAI and Anthropic of racing toward AI advancements without acting responsibly. Coxon said he was leaving the AI industry, and his allegations spread rapidly on the social media platform X, with Anthropic scientist Evan Hubinger later chiming in on X, saying Coxon was "correct."

AI leaders worry antitrust law could stand in the way of what they view as an increasingly urgent push to coordinate a slowdown in AI development. OpenAI has asked members of Congress in recent weeks for clear guidance about whether orchestrating an industry-wide slowdown on frontier AI development would be legal, people close to the company tell WIRED. Substantive coordination on safety between AI labs may risk running afoul of antitrust law, the people say, which poses a significant obstacle to bringing major tech giants on board with the effort. Last weekend, OpenAI's chief scientist, Jakub Pachocki, published a blog post arguing that the best path forward for the AI research world includes "coordinating to slow down future development," which he thinks will be key to ensuring that self-improving AI systems are safe. In the short term, he expects " voluntary slowdowns to become commonplace until shared safety bars are established."

More Anthropic researchers warn of AI's perils as Musk terms fears a'psyop' Insiders at the firm fear tech's advancement could cause human extinction while others are calling it a'setup' A day after a former researcher at Anthropic made an apocalyptic declaration about artificial intelligence, more researchers and staff members at the AI startup publicly agreed with him and posted their own dire warnings. In response, Elon Musk and other conservative figures on X, formerly Twitter, called the chorus of concerns a "setup" and a "psyop". The Anthropic insiders fear the technology they are building could become so advanced and dangerous as to cause human extinction within the decade, and they assert many of their colleagues feel the same but haven't said so publicly. These researchers and staff are posting in response to a now-viral thread from Anthropic researcher Jacob Coxon, who said on Wednesday he was resigning from the company because neither Anthropic nor its competitor OpenAI, also his former employer, were building AI models responsibly and are "gambling with our lives". OpenAI not on track to reduce risk of'catastrophic' loss of control, says board member Anna Wang, who works on Artificial General Intelligence Safety at Anthropic and previously worked at Google's DeepMind, said Thursday that many people at Anthropic want to slow down development to come up with a plan to mitigate the risks that could come with these AI models.
