OpenAI and Anthropic limit frontier model access during U.S. cybersecurity review
OpenAI restricted the rollout of its GPT-5.6 model series at the request of President Donald Trump's administration while the government conducts a cybersecurity review.[1] Help Net Security reported that OpenAI began rolling out GPT-5.6 in limited preview to trusted partners and said the release was being coordinated with the U.S. government before broader availability through ChatGPT, Codex, and the API.[2] AP News reported that Anthropic also limited access to a new model during the review process.[1] The development is notable for AI law because it ties frontier-model deployment to federal cybersecurity review, national-security screening, and government-approved access conditions rather than ordinary commercial release alone.[1][2]
