Trump administration weighs stricter AI model regulation after Anthropic Mythos concerns

The Trump administration is considering applying stricter oversight to powerful AI models like Anthropic's Mythos due to their cybersecurity hacking capabilities, potentially establishing a government review process for new AI model releases. The White House reportedly opposed Anthropic's plan to expand access to Mythos to 70 additional companies. CISA is considering reducing patch deadlines for actively exploited vulnerabilities from three weeks to three days. The UK's AI Security Institute found OpenAI's GPT-5.5 may be better than Mythos at cybersecurity tasks.
