Finance ministers, central bankers and financiers have expressed serious concerns about a powerful new AI model they fear could undermine the security of financial systems.

The development of the Claude Mythos model by Anthropic has led to crisis meetings, after it found vulnerabilities in many major operating systems.

Experts say it potentially has an unprecedented ability to identify and exploit cyber-security weaknesses - though others caution further testing is needed to properly understand its capabilities.

Canadian Finance Minister François-Philippe Champagne told the BBC that Mythos had been discussed extensively at the International Monetary Fund (IMF) meeting in Washington DC this week.

“Certainly it is serious enough to warrant the attention of all the finance ministers,” he said.
