Anthropic has officially suspended the availability of its Fable 5 and Mythos 5 artificial intelligence models just days after their public release. The company confirmed the decision in a blog post, citing a direct order from the United States government. While the specific details of the directive remain limited, the company indicated that the government identified a security concern regarding the models.

There is a notable difference in how the reasoning behind this order is being reported. Wired reports that the government believes there is a method to "jailbreak" or bypass the safety protocols of the Fable 5 model, necessitating its removal. In contrast, NDTV frames the directive primarily as a restriction on foreign nationals accessing the technology. Ars Technica identifies the directive as coming specifically from the Trump administration, though it does not elaborate on the specific security vulnerabilities mentioned by other outlets.

The suspension marks a significant setback for Anthropic, as the models were released only three days prior to the announcement. The company has not provided a timeline for when or if the models will be reinstated, stating only that they are working to comply with the government's security requirements. Industry analysts are currently waiting for further clarification from both the company and federal regulators regarding the scope of the "jailbreak" concerns and the nature of the access restrictions mentioned in the initial reports.
