Anthropic

An AI just found security holes that human hackers missed for 27 years. And the company that built it says you can’t have it. This week, Anthropic did something the AI industry almost never does: it announced its most powerful model ever and simultaneously refused to release it. Claude Mythos Preview isn’t locked behind a paywall or a waitlist. It’s locked behind a vault door, with access restricted to a handpicked coalition of tech giants scrambling to patch the internet before someone else builds something similar. ...

Two deals. Two days. Two of the biggest names in AI writing checks to the same company. On Thursday, Meta committed an additional $21 billion to CoreWeave for AI cloud capacity through 2032. On Friday, Anthropic — the company behind Claude — signed a multiyear agreement to run its workloads on CoreWeave’s infrastructure. CoreWeave’s stock ripped past $103, and its total revenue backlog now exceeds $66.8 billion. For a company that started out mining Ethereum, that’s not a bad week. ...

There’s a new AI model that finds software vulnerabilities humans missed for decades — and its creators are so spooked by what it can do, they’re refusing to release it. Anthropic just unveiled a preview of Claude Mythos, their most powerful model yet. But instead of the usual launch playbook — benchmarks, API waitlists, developer hype — the announcement came wrapped in a warning. Mythos is so capable at finding and exploiting bugs that Anthropic formed an emergency coalition of tech giants to deploy it defensively before the bad guys build something similar. ...

Remember when ChatGPT just answered your questions without trying to sell you anything? Those days are officially over — and OpenAI is counting on it to the tune of $100 billion. OpenAI has told investors it expects $2.5 billion in advertising revenue this year, scaling to $100 billion by 2030. That’s building an ad business in four years that took Google and Meta decades to create. This isn’t some side experiment. This is the company that kicked off the AI revolution fundamentally reshaping how the internet makes money. ...

Forget another chatbot upgrade. The biggest story in AI right now is that the machines are starting to build themselves. Not in the Terminator sense — nobody’s assembling robot armies in a garage. But in a quieter, more consequential way: AI systems are writing the code, optimizing the training runs, and designing the infrastructure that powers their own successors. And the companies behind them aren’t hiding it. They’re putting it on product roadmaps. ...

Stop watching Congress if you want to understand where AI regulation is heading. Watch Sacramento. Governor Gavin Newsom just signed what his office calls a “first-of-its-kind” executive order that tells AI companies something they haven’t heard from American government in a while: prove your technology won’t hurt people, or lose access to the world’s fourth-largest economy. It’s a direct, unmistakable middle finger to the Trump administration’s deregulatory stance on AI. And it might be the most consequential AI policy move of 2026 so far. ...

Anthropic spent months carefully planning the reveal of its most powerful AI model. Then someone forgot to flip a toggle, and the whole thing spilled onto the open internet. On March 26, security researchers discovered nearly 3,000 unpublished files sitting on Anthropic’s public-facing infrastructure — draft blog posts, internal PDFs, and detailed documents describing a model called Claude Mythos, codenamed “Capybara” internally. Anthropic has since confirmed it’s real, it’s in early testing, and it represents what they call a “step change” in AI capabilities. ...

Sometimes the biggest AI announcements aren’t announcements at all. They’re accidents. On March 26, a misconfigured content management system at Anthropic — the $60 billion company behind Claude — spilled nearly 3,000 unpublished assets into a publicly searchable data cache. Among the wreckage: a draft blog post describing Claude Mythos, which Anthropic has since confirmed is “by far the most powerful AI model we’ve ever developed.” This wasn’t a controlled product launch. It was a human error that gave the world an unfiltered look at what’s next in AI. And it’s equal parts thrilling and terrifying. ...

Anthropic just got caught with its pants down. The company building what it calls the most safety-conscious AI on the planet accidentally left its biggest secret on a publicly searchable server. The secret? Claude Mythos — a new model tier that reportedly leapfrogs everything else in the industry. And the kicker? Anthropic’s own internal docs warn that Mythos poses “unprecedented cybersecurity risks.” You can’t write irony this good. What Got Leaked Fortune broke the story Thursday: nearly 3,000 unpublished documents, including a draft blog post announcing Claude Mythos, were sitting in an unsecured data store. Not a sophisticated state-sponsored hack. Not a disgruntled employee. A CMS misconfiguration. Human error. ...

Remember when AI assistants could only talk about helping you? Those days are officially over. Anthropic just dropped what might be the most consequential AI update of 2026: Claude can now take control of your Mac. Not metaphorically — it literally moves your cursor, clicks buttons, types into fields, and navigates your apps. You can text Claude from your phone while grabbing coffee, and by the time you sit back down, your pitch deck is exported, attached to a calendar invite, and ready to go. ...
