U.S. clears Anthropic to redeploy Claude Mythos 5 to vetted domestic organizations

The U.S. government has permitted Anthropic to redeploy its Claude Mythos 5 model to about 100 approved U.S. organizations, partially rolling back a June 12 export-control order that had cut off access. At the same time, OpenAI said it is delaying a full public launch of GPT5.6 at the government’s request and will limit availability to a small set of vetted partners. The moves reflect U.S. national security concerns that frontier AI models could be misused by military intelligence services in China, Russia and other countries of concern. Both companies are planning to go public, but the pace of releases, eligibility standards and transparency remain uncertain under the current oversight approach.
