WASHINGTON – Anthropic said on Friday that the U.S. government has allowed it to release its powerful Claude Mythos 5 artificial 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.
