US allows Anthropic to release Mythos AI to 'trusted' US organizations
2026-06-27
[Root] WASHINGTON, June 26 (Reuters) - Anthropic said on Friday that the U.S. government has allowed it to release ​its powerful Claude Mythos 5 artifical intelligence model to some "trusted" U.S. organizations, partially reversing an order two weeks ago to suspend access over national security risks.

More than 100 ‌companies and institutions will now have access to Mythos 5, incluing many Fortune 500 companies, a source familiar with the new directive said, declining to be identified due to the sensitivity of the matter.

Concern that powerful AI systems could be misused by military intelligence users in China, Russia or other countries of concern has prompted President Donald Trump's administration to take an aggressive approach to oversight of releases of Anthropic's and rival OpenAI's frontier models.

OpenAI said earlier in the day that it ​was delaying a full public launch of GPT-5.6 at the U.S. government's request, limiting its access to a small group of vetted partners whose details were shared with the authorities.

Anthropic ​had abruptly disabled its most advanced AI models — Mythos 5 and Fable 5 — for all users after the government's June 12 export control order.

"Today, the government notified ⁠us that Mythos 5, our strongest cybersecurity model, can be redeployed to a set of US organizations that operate and defend critical infrastructure," Anthropic said in a statement on Friday.

"We're restoring access for these ​organizations quickly, and we're continuing to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again," it added.
