Anthropic shuts down Fable, Mythos models following Trump admin directive

Anthropic shut down access to its Fable 5 and Mythos 5 AI models on Friday, March 15, 2024, shortly after their release. This action followed a directive from the US Commerce Department that placed the models under export controls, prohibiting their use outside the United States. Anthropic stated that disabling the models for all customers was the only immediate way to ensure compliance with the government order. The US administration reportedly expressed concerns over a reported jailbreak vulnerability in Fable 5 that could bypass safeguards related to cybersecurity, chemistry, and biology. According to Axios, an administration official indicated that the directive was intended to allow the "national security apparatus" time to strengthen defenses against such threats, a process that could take "the next few weeks."
