South Korea has begun testing an AI cybersecurity frontier model to set the government\'s response direction to AI security threats and apply results to industry. The Korea Internet & Security Agency (KISA) under the Ministry of Science and ICT has entered tests of OpenAI\'s \'GPT-5.5 Cyber\'. KISA is verifying whether the model can be used to identify and respond to threats and may expand use to software and infrastructure checks. KISA is also moving to secure access to Anthropic\'s Mythos model.
