The US government has asked OpenAI to limit its new GPT-5.6 model to government-approved partners before any wider launch, citing security concerns. The move follows the administration forcing Anthropic to pull its Fable 5 and Mythos 5 models offline weeks earlier.

CEO Sam Altman called the staggered rollout not OpenAI's "preferred" approach, as Washington tightens oversight of powerful AI models under Trump's June executive order.
