[OpenAI Agrees to Grant Access to AI Model to Some Japanese Banks to Strengthen Cybersecurity in the Financial Sector] ⑴ OpenAI has agreed to grant access to its new artificial intelligence model to some Japanese banks, a move that could strengthen Japan's cybersecurity capabilities. ⑵ The Finance Minister stated after meeting with OpenAI executives on Friday, "Given that cutting-edge AI is currently seen as a threat, this move is expected to be a major boost to strengthening cybersecurity in Japan's financial sector." ⑶ Using this model, named GPT-5.5 Cyber, will allow Japan to better examine systemic risks, identify information security vulnerabilities, and take countermeasures. ⑷ Japan's financial industry has been closely monitoring the emergence of cutting-edge AI models, which have become a global concern due to their ability to autonomously identify software vulnerabilities. Models like Anthropic's Claude Mythos and OpenAI's GPT-5.5 Cyber can discover and exploit vulnerabilities at speeds far exceeding human capabilities, raising concerns about the existential threat to financial systems with outdated cybersecurity. ⑸ The Finance Minister stated that some Japanese financial companies will also gain access to Mythos after obtaining relevant government approvals.
