Reuters： National lvel regulators now treat frontier AI models as part of operational risk， like liquidity stress， outages， or cyberattacks， because the same tool that helps defenders can also compress the time between discovery and exploitation.

Japan's Financial Services Agency will meet MUFG， SMFG， Mizuho， the Bank of Japan， and the Tokyo Stock Exchange after concerns around Anthropic's Mythos model spread through the financial system.

The basic worry is that a model built for defensive cybersecurity may be strong enough to expose software weaknesses faster than banks， exchanges， and regulators can patch them.

That changes the risk from ordinary hacking， where humans find bugs one by one， to a system where AI can scan huge codebases， spot patterns， and surface critical flaws at machine speed.
