The Japanese government and the country’s major financial institutions have secured access to Claude Mythos, an advanced artificial intelligence model developed by U.S.-based Anthropic. Finance Minister Satsuki Katayama, who also serves as minister of state for financial services, declined Tuesday to disclose how many Japanese financial companies received the access.

Three megabanks—MUFG Bank, Mizuho Bank and Sumitomo Mitsui Banking—are reportedly included.

Partnership expansion Anthropic announced the same day that it is extending the Mythos partnership to about 150 new organizations in over 15 countries. With Anthropic's Claude Mythos, financial institutions will be able to rapidly detect vulnerabilities in their systems and fix them.
