Reuter： Japanese banks are getting early access to OpenAI's newest model for security testing， which is believed to be on a par with that of rival Anthropic's Claude Mythos.

There were also reports that Japan's three largest banks are expected to gain access to Anthropic Mythos.

Adoption of the new models is expected to help stop new types of cyberattacks. These 2 "frontier AIs" are said to detect vulnerabilities far better than earlier models.
