Anthropic Removes Claude Fable 5 and Mythos 5 Following US Government Directive
Anthropic has taken the unusual step of removing two of its Claude AI models—Fable 5 and Mythos 5—from public availability. The company cited a US government directive as the reason for the sudden removal, but has not provided specifics about what the directive entails or why these particular models were targeted.
The removal affects all users who previously had access to these models. Anthropic has not yet announced when or if the models will be reinstated, or what alternative offerings might be available in the meantime.
This incident highlights the increasing regulatory scrutiny that advanced AI systems face from government authorities. As AI capabilities grow more powerful, authorities are implementing new controls and restrictions on certain model deployments, particularly those with enhanced reasoning or multi-modal capabilities.
