Japan megabanks set to win Mythos access after Bessent visit

MUFG Bank, Mizuho Bank and Sumitomo Mitsui Banking are all likely to gain access to Anthropic's artificial intelligence model, Mythos. Japan's three megabanks are set to secure access to Anthropic's artificial intelligence model, Mythos, according to a person familiar with the matter, after its limited release last month sparked fears of a new age of cybersecurity risks. MUFG Bank, Sumitomo Mitsui Banking Corp. and Mizuho Bank are all likely to gain access to the artificial intelligence model developed by the U.S. firm, the person said, asking not to be identified because the information is private. The planned access was earlier reported by Nikkei. The move comes as financial institutions around the world grow alarmed about the risks created by Mythos, which has an unprecedented ability to detect software vulnerabilities. That has raised concerns that hackers could use Mythos to disrupt critical infrastructure, and access has so far been limited to a small number of U.S. companies and organizations.
