Anthropic’s Mythos AI Tool to Reach UK Banks Soon
British banks will gain access within the next week to Anthropic’s powerful AI tool, Mythos, which has been considered too risky for public release. Senior finance officials have expressed concerns regarding its potential impact.
Anthropic, which has so far limited the deployment of Mythos to a select group of mainly US companies such as Amazon, Apple, and Microsoft, announced plans to extend access to financial institutions in the UK.
“That is in the very near term, in the next week,” Pip White, Anthropic’s head of UK, Ireland and northern Europe operations, stated during a Bloomberg TV interview.
“As you would expect, the engagement I have had from UK CEOs in the last week has been significant.”
Anthropic, the developer behind the Claude family of AI models, has warned that Mythos presents an unprecedented risk due to its capability to identify vulnerabilities in IT systems.
“AI models have reached a level of coding capability where they can surpass all but the most skilled humans at finding and exploiting software vulnerabilities,” Anthropic explained in a blog post earlier this month.
“The fallout – for economies, public safety, and national security – could be severe.”
Global Finance Leaders Address Risks Amid Geopolitical Tensions
Finance ministers, executives, and regulators convened in Washington this week for the International Monetary Fund and World Bank spring meetings to discuss potential threats posed by AI technologies like Mythos. Discussions also included concerns about global repercussions stemming from the US-Israeli conflict involving Iran.
Canada’s finance minister, François-Philippe Champagne, emphasized the seriousness of the issue in an interview with the BBC.
“Certainly it is serious enough to warrant the attention of all the finance ministers … The difference with the financial crisis is that we know where it is and we know how large it is.
“The issue that we’re facing with Anthropic is that it’s an unknown unknown. It requires a lot of attention so that we have safeguards, and we have processes in place to make sure that we ensure the resiliency of our financial system.”
Andrew Bailey, governor of the Bank of England and chair of the Financial Stability Board, described the challenge as significant.
“It is a very serious challenge for all of us. It reminds us how fast the AI world moves.”
Bailey noted the difficulty regulators face in determining the appropriate timing and extent of regulatory measures, as governments aim to balance AI’s economic benefits with security concerns.
“What is the optimum moment to frame the rules of the road?” Bailey asked.
“If you go too early you a) risk missing the target and b) you risk distorting the evolution, and if you go too late things can get out of control.”
Christine Lagarde, president of the European Central Bank, highlighted the dual nature of Anthropic’s developments.
“The development we’ve seen with Anthropic and Mythos is a good example of a responsible company that is suddenly thinking: ‘Ah, that could be really good’ – but if it falls in the wrong hands, it could be really bad.”
“Everybody is keen to have a framework within which to operate,” Lagarde told Bloomberg TV.
“But I don’t think there is a governance framework that is there to actually mind those things. We need to work on that.”
US and UK Regulatory Responses Underway
US Treasury Secretary Scott Bessent convened a meeting in Washington last week focused on the Mythos model, addressing systemically important banks where operational disruption or failure could threaten financial stability.
UK regulators plan to raise concerns about Mythos’s risks with bank executives and government officials in the coming weeks.
Dan Katz, deputy head of the International Monetary Fund and former chief of staff to Bessent, stressed the urgency of addressing cybersecurity risks posed by digital technologies.
“The evolution of digital technology is posing immense risks from a cybersecurity perspective … this is really going to be absolutely essential on the international agenda for the next few months.”
