Japan's megabanks set to access Anthropic's Mythos as soon as this month, Nikkei says

By Anton Bridge

TOKYO, ‌May 13 (Reuters) - ​Japan's ​three largest banks are set to acquire access to Mythos, the artificial ‌intelligence model developed by Anthropic, as soon ⁠as the end of May, the Nikkei business ‌daily reported on Wednesday.

The ‌banking arms of Mitsubishi UFJ Financial Group, Sumitomo Mitsui Financial Group, and Mizuho Financial ​Group were likely to have been informed of the move by U.S. Treasury Secretary ⁠Scott Bessent at a meeting in Japan on Tuesday, the ​Nikkei said.

• This would mark the first time a Japanese company has been ​granted access to Mythos, ‌the Nikkei said.

• Mythos is designed for defensive cybersecurity tasks but ⁠its capabilities have sparked fears about the threat to traditional software security as Anthropic said a ⁠preview had uncovered many major vulnerabilities affecting every major ​operating system and web browser.

• On Tuesday, Japanese Finance Minister Satsuki Katayama met Bessent and later said Japan ‌would establish a public-private working group this week to address cybersecurity ‌risks to the Japanese financial system posed ⁠by Mythos.

• The group's ‌first meeting is ​expected to be held on Thursday.
