OpenAI and Anthropic Limit New AI Models to Trump-Approved Customers During Cybersecurity Review

This article reports on a significant shift in the release strategy of AI models ChatGPT and Anthropic’s Claude, driven by a government-led cybersecurity review initiated by the Trump administration. OpenAI is restricting access to its new GPT-5.6 Sol model to customers approved by the administration, while Anthropic has partially restored access to its Mythos 5 model for a limited group of cyber defenders. The move highlights growing concerns within the government regarding the potential cybersecurity risks posed by advanced AI models and reflects a broader effort to regulate AI development and deployment.
