Is Anthropic's Mythos AI too powerful? Bankers and ministers get into a huddle and raise concerns - key points to know

Anthropic Mythos financial system risk: A powerful new AI model from Anthropic is raising serious concerns among global financial leaders, with finance ministers, central bankers, and top executives holding discussions over its potential risks to financial systems.

Claude Mythos, part of Anthropic's broader Claude AI family and a rival to tools from OpenAI and Google, has drawn attention for its ability to identify and potentially exploit cyber-security vulnerabilities. The model was discussed extensively at a recent meeting of the International Monetary Fund in Washington DC, as per a report.

Canadian Finance Minister François-Philippe Champagne said the issue is serious enough to demand attention from finance ministers globally, describing the challenge as an "unknown" risk that requires safeguards to protect financial system resilience.

Champagne explained that, "The difference is that the Strait of Hormuz - we know where it is and we know how large it is... the issue that we're facing with Anthropic is that it's the unknown, unknown," adding, "This is requiring 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 systems," as quoted by BBC.

Mythos is one of Anthropic's latest AI models, designed to test how systems handle so-called "misaligned" task, those that go against expected human behavior. Early testers described it as "strikingly capable" in computer security tasks, particularly in identifying software bugs and vulnerabilities.

Anthropic has chosen not to release Mythos widely due to concerns that it could expose or exploit weaknesses in critical systems. Instead, access has been limited to select partners such as Amazon Web Services, CrowdStrike, Microsoft, and Nvidia under an initiative called Project Glasswing.

While some experts warn about its unprecedented capabilities, others urge caution. The UK AI Security Institute, which has independently tested the model, said Mythos can exploit weak systems but is not dramatically more advanced than its predecessor, Opus 4, as reported by the BBC.

Top financial institutions are taking the threat seriously. Barclays CEO CS Venkatakrishnan said that, "It's serious enough that people have to worry," adding, "We have to understand it better, and we have to understand the vulnerabilities that are being exposed and fix them quickly," as quoted by BBC.

Bank of England governor Andrew Bailey warned that such AI tools could make it easier for cybercriminals to detect and exploit weaknesses in core IT systems. He said, "We are having to look very carefully now what this latest AI development could mean for the risk of cyber crime," adding, "The consequence could be that there is a development of AI, of modelling, which makes it easier to detect existing vulnerabilities in sort of core IT systems, and then obviously cyber criminals - the bad actors - could seek to exploit them," as quoted by BBC.

Meanwhile, the United States Department of the Treasury has urged major banks to test their systems ahead of any public release of Mythos.

Governments and financial institutions are being given early access to test their defenses, as concerns grow that similar models could soon emerge from other AI companies without the same safeguards.

Investor James Wise of Balderton Capital said Mythos may be the first of many such models, adding that efforts are already underway to invest in AI systems designed to both detect and fix vulnerabilities, as per the report.

Has Mythos been released publicly?

No, access is limited due to security risks.

Who is using it right now?

Selected partners like AWS, Microsoft, Nvidia, and CrowdStrike.
