Mythos returns as agentic AI drives security operations center expansion

The U.S. government has lifted export controls on Anthropic’s top AI models, Claude Fable5 and Mythos5, raising expectations of renewed competition among companies seeking to deploy AI models in cyber security. OpenAI has also made limited releases of three GPT-5.6 models, including a top model focused on cyber security. Companies are moving to apply agentic AI to security operations centers, while firms and institutions in and outside South Korea outline new security initiatives and strategies.
