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.
"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."
"this is requiring a lot of attention so that we have safeguards, and we have process in place to make sure that we ensure the resiliency of our financial systems," he added.
