Anthropic’s Mythos 5 is back
Following extensive negotiations with the Trump administration, Anthropic has received approval to redeploy its cybersecurity model, Mythos 5, to a select group of organizations. This is a significant shift, allowing restricted access to enhanced capabilities for entities deemed trustworthy. However, availability of the public-facing Fable 5 model remains unsettled, as no clear timeline for its rollout has been established. The U.S. government continues to impose restrictions on export compliance, hindering wider access for non-U.S. nationals while allowing exceptions for Mythos 5.
