Anthropic is investigating a claim that a small group of people gained access to its Claude Mythos model - the cyber-security tool which the AI firm says is too powerful to release to the public. We're investigating a report claiming unauthorized access to Claude Mythos Preview through one of our third-party vendor environments, the company said in a statement. It was in response to a Bloomberg report that users in a private forum managed to access the model without the normal permissions. There is deep unease about Mythos' capabilities - though the UK's top cyber official has said advanced AI tools could be a net positive if the technology was secured from misuse. There is currently no suggestion that malicious actors have managed to get hold of the model, and Anthropic says it does not have evidence its systems are affected.

AI firm Anthropic seeks weapons expert to stop users from'misuse' The US artificial intelligence (AI) firm Anthropic is looking to hire a chemical weapons and high-yield explosives expert to try to prevent catastrophic misuse of its software. In other words, it fears that its AI tools might tell someone how to make chemical or radioactive weapons, and wants an expert to ensure its guardrails are sufficiently robust. In the LinkedIn recruitment post, the firm says applicants should have a minimum of five years experience in chemical weapons and/or explosives defence as well as knowledge of radiological dispersal devices - also known as dirty bombs. The firm told the BBC the role was similar to jobs in other sensitive areas that it has already created. Anthropic is not the only AI firm adopting this strategy.

Elon Musk's SpaceX is taking over his artificial intelligence (AI) start-up, as the billionaire continues to unify some of his many business interests. SpaceX confirmed the deal to acquire xAI, a smaller firm known for its Grok chatbot, posting a memo from Musk about the merger on its website. In the note, Musk said the combination would form an innovation engine putting AI, rockets, space-based internet, and media under one roof. Terms of the deal were not disclosed. However, a source familiar said it valued xAI at $125bn (£91bn) and SpaceX at $1tn, making it the most valuable private company ever.

Johansson was dragged into the AI debate after OpenAI's voice assistant used her vocal likeness, prompting the actor to say she was'angered' by the move. Johansson was dragged into the AI debate after OpenAI's voice assistant used her vocal likeness, prompting the actor to say she was'angered' by the move. Scarlett Johansson, Cate Blanchett, REM and Jodi Picoult are among hundreds of Hollywood stars, musicians and authors backing a new campaign accusing AI companies of "theft" of their work. The "Stealing Isn't Innovation" drive launched on Thursday with the support of approximately 800 creative professionals and bands. It adds: "Artists, writers, and creators of all kinds are banding together with a simple message: Stealing our work is not innovation.

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.

Disney and OpenAI have made a surprise deal - what happens next? Disney's famous Mickey Mouse character will soon be available for use in AI-generated videos The world's best-known AI company and the world's best-known entertainment firm have come to a surprise agreement to allow AI versions of some of the most iconic characters in film, TV and cartoons to be used in generative AI videos and images. Social media is dead - here's what comes next The Walt Disney Company has signed a deal with OpenAI that will allow the AI firm's Sora video generation tool and ChatGPT image creator to use more than 200 of Disney's most iconic characters. Meanwhile, Disney remains in dispute with another AI firm, Midjourney, over alleged infringement of their intellectual property (IP), claiming Midjourney aims to "blatantly incorporate and copy Disney's and Universal's famous characters" into their image generating tool. The characters now deemed fair game for OpenAI users include the likes of Mickey and Minnie Mouse, Simba and Mufasa from and Moana, as well as Marvel and Lucasfilm characters, including some of's most well-known names.

The three years since the release of ChatGPT, OpenAI's generative AI chatbot, have seen huge changes in every part of our lives. Social media is dead - here's what comes next The most high-profile case was filed by Disney and Universal in June, both of whom alleged in a lawsuit that AI image generator Midjourney had been trained on their intellectual property, allowing users to create images that "blatantly incorporate and copy Disney's and Universal's famous characters". The latest on what's new in science and why it matters each day. In October, the Japanese government formally asked OpenAI, the company behind the Sora 2 AI video generator, to respect the intellectual property rights of its culture, including manga and popular video games such as those published by Nintendo. Sora 2 has faced further controversy due to its ability to create lifelike footage of real people.

UK share values'most stretched' since 2008, Bank warns The Bank of England has warned of a sharp correction in the value of major tech companies with growing fears of an artificial intelligence (AI) bubble. It said share prices in the UK are close to the most stretched they have been since the 2008 global financial crisis, while equity valuations in the US are reminiscent of those before the dotcom bubble burst. The central bank's financial stability report warned valuations are particularly stretched for companies focused on AI. It said the growth of the sector in the next five years would be fuelled by trillions of dollars of debt, raising financial stability risks if the value of the companies falls. The Bank of England cited industry figures forecasting spending on AI infrastructure could top $5tn (£3.8tn).

The Anthropic chief executive, Dario Amodei, has flagged various concerns about its AI models recently. The Anthropic chief executive, Dario Amodei, has flagged various concerns about its AI models recently. AI firms must be clear on risks or repeat tobacco's mistakes, says Anthropic chief Artificial intelligence will become smarter than'most or all humans in most or all ways', says Dario Amodei Mon 17 Nov 2025 06.35 ESTLast modified on Mon 17 Nov 2025 07.25 EST Artificial intelligence companies must be transparent about the risks posed by their products or be in danger of repeating the mistakes of tobacco and opioid companies, according to the chief executive of the AI startup Anthropic. Dario Amodei, who runs the US company behind the Claude chatbot, said he believed AI would become smarter than "most or all humans in most or all ways" and urged his peers to "call it as you see it". Speaking to CBS News, Amodei said a lack of transparency about the impact of powerful AI would replay the errors of cigarette and opioid firms that failed to raise a red flag over the potential health damage of their own products.

A senior ministerial aide said AI companies would never have to compensate creatives for using their content to train their systems, in a statement that has alarmed campaigners demanding Labour deliver a fairer deal for musicians, artists and writers from the tech industry. Kirsty Innes, recently appointed as a special adviser to Liz Kendall, the secretary of state for science, innovation and technology, said "whether or not you philosophically believe the big AI firms should compensate content creators, they in practice will never legally have to". The government is consulting on how creatives should be compensated by AI firms and only last week leading British artists including Mick Jagger, Kate Bush and Paul McCartney urged Keir Starmer to stand up for creators' human rights and protect their work. Innes, who previously worked at the Tony Blair Institute (TBI) thinktank, has deleted the statement, which she posted to X in February, seven months before she became a ministerial adviser. In the deleted posts, seen by the Guardian, she said: "A lot of this has already happened and it can continue to happen outside the UK, whatever our laws say."
