Japan's three largest banks-Mitsubishi UFJ Financial Group, Sumitomo Mitsui Financial Group, and Mizuho Financial Group-are set to gain access to Mythos, the artificial intelligence model developed by Anthropic, as soon as the end of May, according to a Nikkei report.
This marks the first time a Japanese company has been granted access to Mythos. The model is designed for defensive cybersecurity tasks, but its capabilities have raised concerns over threats to traditional software security. Anthropic says a preview uncovered major vulnerabilities affecting every major operating system and web browser.
Japanese Finance Minister Satsuki Katayama met with U.S. Treasury Secretary Scott Bessent in Tokyo on Tuesday. Following the meeting, Katayama announced a public-private working group to address cybersecurity risks to Japan's financial system posed by Mythos. The group's first meeting is expected Thursday.
