Claims
- The US government issued an export-control directive barring any foreign national from using Anthropic's Fable 5 and Mythos 5 models, forcing Anthropic to take them offline.
- Anthropic publicly acknowledged that Mythos 5 has advanced dual-use capabilities for both finding and exploiting software vulnerabilities.
- Anthropic pre-released Mythos 5 privately to a restricted consortium called Project Glasswing before its public launch.
- Claude Fable 5 was released to the general public with specific capability blocks on biology and cybersecurity responses.
- Anthropic had been in talks with the White House since Friday but had not yet secured an agreement to reinstate the models at time of publication.
Key quotes
A great deal of advanced usage of AI models is dual use: the same queries that are beneficial in the hands of cybersecurity professionals and biology researchers could be dangerous if available to malicious actors.
