This is health care's Uber moment. Every knowledge-based profession may one day reach the point when AI outperforms the human experts. In medicine, that day appeared to come in April. A group of primarily Harvard and Stanford researchers announced the results of a study that pitted ChatGPT against hundreds of physicians in a diagnostic obstacle course involving written medical mysteries and information from real-world patients. The bot had won, and the humans weren't entirely happy about it.

'Pretty Crazy' Token Usage Is Testing Bosses' Bet on AI A Silicon Valley software maker and an ecommerce company reveal to WIRED how they are navigating the emerging challenge of "tokenomics." At the software company 8x8, employees are using Anthropic's Claude to draft emails, analyze customer feedback, and write code, but so far, their growing reliance on the artificial intelligence chatbot hasn't troubled the finance team. While other Silicon Valley companies, such as Meta, Uber, and Salesforce, have publicly expressed concerns about the growing cost of generative AI tools and have begun introducing usage caps in some cases, 8x8 says it finds itself in the black. Over the past 18 months, the company estimates it has saved about $5 million in annual costs by canceling subscriptions to dozens of software and educational tools it deemed unnecessary in part because Claude could provide similar capabilities. So far, 8x8's annualized bill for Claude is "well below" that figure, says Joel Neeb, the company's chief transformation and business operations officer.

Bosses at the artificial intelligence (AI) firm Anthropic are set to meet senior White House officials amid fresh national security concerns over the company's latest release. The meeting is set to take place on Monday in Washington DC between executives at Anthropic and the US Department of Commerce, a government department led by Secretary Howard Lutnick, according to two people familiar with the matter. It comes after Anthropic blocked all public access to the recent release of its latest AI tool on Friday, which it has previously said is too powerful. The firm made the decision after the US government prohibited Anthropic from allowing any foreign national access to the technology. The AI tool at issue is named Fable 5 or Mythos 5. Fable 5 is a version of the tool with extra safeguards made available to the public, while Mythos 5 has different controls and is only available to a select group of organisations.

Plus: Anthropic has shut down access to its top models after a US directive. That's good for our health, but bad for the planet: it already accounts for 7% of global electricity use and 3% of greenhouse-gas emissions. Feeling the heat, scientists and startups are hoping to amp up solid-state cooling. These systems move heat through conductive materials, which could cool spaces and surfaces with fewer messy side effects. The catch is whether it can match the efficiency of traditional AC. Find out how the unconventional coolers aim to dial down AC emissions .

Anthropic has suspended its powerful new AI model after US authorities raised security concerns just days following its public release. In a statement published on its website, Anthropic said it was ordered to suspend foreign nationals from using Claude Fable 5, a program that the company self-described as too powerful. The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance, the company wrote. Anthropic and the Trump administration are involved in a separate ongoing lawsuit over an order to stop government agencies using the company's AI tools. The BBC has approached the US Department of Commerce for comment.

Version of AI tool'too powerful for public' released to public A version of an artificial intelligence (AI) tool which the company said was too powerful to be released to the public has just been released to the public. Claude Fable 5 is a version of Anthropic's Claude Mythos, an AI program which caused serious concerns among technology, finance, and government leaders when it was released privately in April for previewing and testing. Some worry the tool is so powerful it could pose financial security risks, though others have questioned how much of the hype is marketing spin. Anthropic said on Tuesday Fable will be released with safeguards and user limitations in place, though it said releasing a model this capable comes with risks. Fable's capabilities exceed those of any model we've ever made generally available, it added.

Alan Turing proposed a test for machine intelligence: could a computer convince a human it was human? Recently, a friend told me over coffee about some disheartening feedback she had received. "They said it was good," she said, "but that it read like it was written by AI." Knowing her, I understood immediately what had happened. Her credibility was being questioned not because her work was poor, but because it was too good - too clear, too fluent, too polished. The rapid acceleration of artificial intelligence tools is changing how we think about good writing.

We Asked the Author to Explain How He Used AI. A book about how AI shapes perceptions of reality came under fire for using AI-generated quotes. Its problems go beyond that. Earlier this month, WIRED published an excerpt from Steve Rosenbaum's buzzy new book,, which looks at how artificial intelligence warps people's sense of reality. Shortly thereafter, The New York Times reported that the book contained over a half-dozen made-up or misattributed quotes.

At the first-ever TIME100 AI Leadership Forum in New York City on Wednesday night, three leaders from music, fashion, and entertainment spoke during an onstage panel about how AI has changed how they worked creatively and the role they see for AI in the arts, moderated by TIME deputy editor Kelly Conniff. Across the board, the panelists agreed that AI is best used as partner and collaborator and cannot replace the distinctly human parts of the creative process. However, they can help users gain deeper knowledge, and shorten the more tedious parts of the brainstorming and ideation process. Christopher Brearton, partner at independent studio AGBO, said that using AI tools could look like leaving a story idea meeting with not only a rough plot and characters but also a quick mockup with images and videos of what it might look like. "Having an AI tool to help open that aperture and expand and continue the creative momentum, and not have breaks in your creative process, has been really fundamentally changing what we do," he said.

An ethical hacker who just won major prizes at a prestigious international competition says her days of competing could be numbered due to the rise of AI tools like Claude Mythos. Valentina Palmiotti - better known as Chompie - was the most successful individual at the annual Pwn2Own hacking competition in Berlin. She told BBC News that, for now, AI tools were helping her to win bug bounties - money given to hackers who spot vulnerabilities in online systems before they can be exploited by cyber-criminals. But she said systems like Mythos were so powerful that even champion hackers like her would soon struggle to compete with them. AI has shaken the cyber-security world, with concerns focussing on Mythos in particular.
