If had debuted this year, William Shakespeare might have been accused of writing it with AI. A certain suspicious rhetorical device appears again and again in the play. It's in Act I, Scene ii: "The fault, dear Brutus, is not in our stars, but in ourselves." In Act III, Scene ii: "Not that I loved Caesar less, but that I loved Rome more." And later in that same scene: "I come to bury Caesar, not to praise him."

OpenAI's Head of Safety Is Leaving the Company Johannes Heidecke's departure comes as OpenAI tries to further integrate its research and safety teams. OpenAI's head of safety systems Johannes Heidecke told staff this week that he's leaving the company, WIRED has learned. Heidecke's departure follows a reorganization that sought to integrate OpenAI's safety and research teams. In a memo to staff seen by WIRED, chief research officer Mark Chen said OpenAI's safety teams will now report to the company's VP of research and head of alignment Mia Glaese, who will take on an expanded role as VP of research and safety. Saachi Jain, who previously led safety teams at OpenAI, will become the company's interim head of safety systems, reporting to Glaese.

The iPhone-maker claims OpenAI encouraged poached Apple employees to bring over confidential presentations, secret prototypes, and key supplier details. Apple filed a lawsuit against OpenAI and its hardware chief on Friday for allegedly stealing the iPhone-maker's trade secrets, including unreleased parts and prototypes, confidential designs, and documents about stealth projects. The lawsuit accuses OpenAI chief hardware officer Tang Tan, who spent 24 years at Apple and oversaw iPhone product design, and his colleagues at the AI company of encouraging people departing or considering leaving Apple to bring with them proprietary and unreleased technology. Tan allegedly helped coach recruits on how to evade Apple's data security protocols and directed them to bring confidential Apple parts to job interviews at OpenAI. "OpenAI's nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets," Apple says in the lawsuit, which was filed in US district court in San Jose.

Mathematicians put AI to work on Fermat's last theorem At an event in London, mathematicians have made unexpectedly fast progress on formalising Fermat's last theorem using AI In the lobby of a central London hotel, tourists are bracing themselves for a day of sightseeing in a heatwave. Meanwhile, staff are resetting the dining room after breakfast. And in a windowless meeting room, assembled academics are contemplating whether humans have a role to play in the future of mathematics, now that AI can prove theorems by itself. The general mood in the room is one of bewilderment at the recent jump in computer intelligence and excitement about the potential it unlocks - and perhaps a slight unease about what the future holds for them personally. Twenty-five researchers from diverse fields and countries are here to spend a week working on formalising Fermat's last theorem with cutting-edge AI models.

OpenAI released its latest advanced AI model, called ChatGPT 5.6. OpenAI released its latest advanced AI model, called ChatGPT 5.6. Staggered release of ChatGPT 5.6 follows similar restrictions on rival firm Anthropic's latest AI models OpenAI released its latest advanced AI model, called ChatGPT 5.6, on Thursday after earlier delaying the public rollout over US government concerns about cybersecurity. The Trump administration had requested last month that OpenAI limit the release to a small group of government-approved users. OpenAI complied with the White House's request last month.

Claude subscribers must soon pay usage-based fees to access Anthropic's best consumer AI model--a sign that the golden era of AI subscriptions is ending. AI model developers have long offered consumers a simple deal: Use our technology for free through an online chatbot, or pay a monthly subscription to receive more usage, premium features, and advanced models. Anthropic is about to make that bargain a lot more complicated. Starting on July 12 at 11:59PM PT, subscribers to Anthropic's $20, $100, and $200-a-month plans will need to pay additional usage-based fees to access Claude Fable 5, the consumer version of the company's highly capable Mythos 5 AI model . This appears to be the first time a frontier AI lab has gated a consumer AI model behind usage-based billing.

OpenAI's Chief Futurist Is Leaving the Company Joshua Achiam spent nearly nine years at OpenAI researching AI safety and made a memorable appearance in the trial. OpenAI's chief futurist, Joshua Achiam, notified colleagues on Tuesday that he is leaving the company later this month after nearly nine years, WIRED has learned. Achiam, who previously led a team tasked with upholding the organization's nonprofit mission, told OpenAI staff that his departure was not motivated by any specific reason, but was something he's been thinking about for a while. "The world is in on the secret now and it feels possible to work on the mission from outside the walls of a frontier lab," Achiam said in a note to staff obtained by WIRED. "I believe we can get to a world of peace, unprecedented prosperity, and unimaginable possibilities, social and scientific. Whatever I do next, I will continue to work with you on making this vision real."

OpenAI says GPT-5.6 Sol will launch with a limited preview for trusted partners approved by the Trump administration before broader ChatGPT and API availability.

Can the biggest problems in AI be solved by philosophy? Some of the biggest challenges in artificial intelligence are being worked on not by computer scientists head down in code but by philosophers lured from academia into jobs at AI firms. The philosophers are tasked with making the next generation of models more capable and reliable, but they also shed light on the mystery of consciousness and whether intelligence can be replicated in software alone. Jonathan Birch at the London School of Economics and Political Science says AI companies are the big employers of philosophy PhDs right now, with offers of interesting work, large salaries and stock options proving too tempting for many to resist. "Topics that have been researched in philosophy departments for decades - how to make rational decisions, how to systematise moral principles, what counts as thinking or reasoning or introspection, what counts as evidence of consciousness - are suddenly of massive value to AI companies," says Birch. "So, naturally, we are seeing a huge brain drain."

AI is'not smart' so what's next in artificial intelligence? We don't have robots that are nearly as good at understanding the physical world as a rat, says Yann LeCun, one of the leading figures in the world of artificial intelligence. He worked at Facebook-owner, Meta, for a decade, where he was chief AI scientist, but left in 2025 and founded Advanced Machine Intelligence Labs (AMI Labs). His goal is to move AI beyond current systems like ChatGPT, Claude and Gemini. They have their uses, he says, but will never be able to tackle complicated situations in the real world, like getting a robot to do household chores.
