According to a report from WIRED, Anthropic deactivated two AI models released this week —Claude Fable 5 and Mythos 5— to comply with a U.S. government order based on export controls. The information has not been confirmed by the company or the BIS as of this edition.

The U.S. has intensified controls over critical technologies such as advanced artificial intelligence. In January 2025, the BIS issued a "Framework for Artificial Intelligence" establishing new regulations. The reported order would be a direct application of that framework, but no specific regulatory instrument has been published yet.
