Anthropic Says It's Taking Claude Fable 5 Offline to Comply With US Government Order "The government believes it has become aware of a method of bypassing, or'jailbreaking' Fable 5," the company said in a blog post. Anthropic says it's disabling two AI models it launched earlier this week, Claude Fable 5 and Mythos 5, to comply with an export control directive it received Friday afternoon from the US government citing national security concerns. The unprecedented incident marks the latest flashpoint between Anthropic and the Trump administration . While the company says the order asked it to suspend access to "any foreign national, whether inside or outside the United States, including foreign national Anthropic employees," it has removed access for all of its customers to ensure compliance. Earlier this year, Trump's Department of Defense labeled Anthropic a " supply chain risk " after the Claude-maker sought to draw red lines over how the US military could use its technology.

You don't need to worry about recursive-self-improving AI - yet One of the world's leading artificial intelligence companies has implored the industry to pause development on AI, because the latest models could be reaching a tipping point where they become capable of redesigning themselves, growing ever more powerful and finally escaping our control. At least, that's what the headlines said. In truth, Anthropic's co-founder Jack Clark and the boss of spin-out think-tank The Anthropic Institute, Marina Favaro, have published a long blog post bigging up the capabilities of their Claude model, shortly before the company floats on the stock exchange in an initial public offering (IPO) for a rumoured $1 trillion. Let's, for a moment, ignore the vast financial elephant in the room and look at the technological claims. An AI that becomes capable of designing a more powerful version of itself, which is in turn able to pull off the same feat, is an obvious gamechanger, but it is also not a new idea.

Do you need to worry about Mythos, Anthropic's computer-hacking AI? A powerful AI kept from public access because of its ability to hack computers with impunity is making headlines around the world. But what is Mythos, does it really represent a risk and might it even be used to improve cybersecurity? Anthropic's Project Glasswing aims to improve online security The past few weeks have brought apparently alarming news of Mythos, an AI that can identify cybersecurity flaws in a matter of moments, leaving operating systems and software vulnerable to hackers. The cybersecurity community is now beginning to get a better sense of how Mythos may change the face of cybersecurity - and not necessarily for the worse.

Outside OpenAI's headquarters, a handful of people gathered on Monday holding pieces of colorful chalk. They got down on their knees and started writing messages on the sidewalk. Please no legal mass surveillance. At issue was a business deal that the company recently signed with the Department of Defense, following the Pentagon's sudden turn against Anthropic . OpenAI will now supply its technology to the military for use in classified settings, the sorts that may involve wartime decisions and intelligence-gathering--an agreement, many legal experts told me, that could give the government wide-ranging powers.

To some, METR's "time horizon plot" indicates that AI utopia--or apocalypse--is close at hand. The truth is more complicated. Every time OpenAI, Google, or Anthropic drops a new frontier large language model, the AI community holds its breath. It doesn't exhale until METR, an AI research nonprofit whose name stands for "Model Evaluation & Threat Research," updates a now-iconic graph that has played a major role in the AI discourse since it was first released in March of last year. The graph suggests that certain AI capabilities are developing at an exponential rate, and more recent model releases have outperformed that already impressive trend. That was certainly the case for Claude Opus 4.5, the latest version of Anthropic's most powerful model, which was released in late November.

Elon Musk Is Rolling xAI Into SpaceX--Creating the World's Most Valuable Private Company By fusing SpaceX and xAI--which acquired X last year--Elon Musk tightens his grip over technologies that shape national security, social media, and artificial intelligence. Elon Musk's rocket and satellite company SpaceX is acquiring his AI startup xAI, the centibillionaire announced on Monday. In a blog post, Musk said the acquisition was warranted because global electricity demand for AI cannot be met with "terrestrial solutions," and Silicon Valley will soon need to build data centers in space to power its AI ambitions. "In the long term, space-based AI is obviously the only way to scale," Musk wrote. "The only logical solution therefore is to transport these resource-intensive efforts to a location with vast power and space. I mean, space is called'space' for a reason."

Altman's campaigning for his company coincides with its use of enormous present resources to serve an imagined future OpenAI CEO Sam Altman poses during the Artificial Intelligence (AI) Action Summit, at the Grand Palais, in Paris, on February 11, 2025. Sam Altman has claimed over the years that the advancement of AI could solve climate change, cure cancer, create a benevolent superintelligence beyond human comprehension, provide a tutor for every student, take over nearly half of the tasks in the economy and create what he calls "universal extreme wealth". In order to bring about his utopian future, Altman is demanding enormous resources from the present. As CEO of OpenAI, the world's most valuable privately owned company, he has in recent months announced plans for $1tn of investment into datacenters and struck multibillion-dollar deals with several chipmakers. If completed, the datacenters are expected to use more power than entire European nations .

Ads Are Coming to ChatGPT. OpenAI says ads will not influence ChatGPT's responses, and that it won't sell user data to advertisers. OpenAI plans to start testing ads inside ChatGPT in the coming weeks, marking a significant shift for one of the world's most widely used AI products. The company announced Friday that initial ad tests will roll out in the United States before expanding globally. OpenAI says ads will not influence ChatGPT's responses, and that all ads will appear in separate, clearly labeled boxes directly below the chatbot's answer.

Meta says it is acquiring the Chinese-founded AI firm Manus as it looks to boost the capabilities of its tech. Bloomberg analysts and The Wall Street Journal suggested the purchase could be worth more than $2bn (£1.48bn). Meta said the deal would help improve its own AI by giving people access to agents - tools which can do complex things with minimal user interaction such as planning trips or making presentations. Manus's exceptional talent will join Meta's team to deliver general-purpose agents across our consumer and business products, including Meta AI, it said in a blog post. Barton Crockett, analyst at Rosenblatt Securities, told Reuters it was a natural fit for Meta, which extended into boss Mark Zuckerberg's vision of personal AI using agents.

A rock may block the path, but the robot doesn't know exactly where the rock is. If it did, the problem would be reasonably easy: plan a route around it. But with uncertainty about the obstacle's position, the robot must learn to operate safely and efficiently no matter where the rock turns out to be.
