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

OpenAI and Anthropic are releasing their newest AI models to limited, Trump administration-approved customers following unprecedented government cybersecurity reviews. OpenAI's GPT-5.6 Sol will be accessible only to approved partners, while Anthropic received clearance to deploy its Mythos 5 model to select cyber defenders after earlier being blocked by export controls. The government scrutiny stems from concerns that these powerful AI models could find software vulnerabilities that hackers might exploit, though critics warn the unpredictable interventions could hamper US tech companies as they compete globally and consider going public.
