Anthropic Pulls Fable 5 Offline Amid US Export Controls on Advanced AI Model
Anthropic has taken its latest AI model, Fable 5, offline following US government export controls that the company said it could not reasonably comply with.
The controls, announced on Friday, targeted both Fable 5 and the Mythos model it is based on. Under the restrictions, foreign nationals—even those employed by Anthropic at the company's US offices—were barred from accessing the models. In response, Anthropic removed both systems from public availability.
The situation remains unresolved. As of Tuesday, Fable remained offline while both Anthropic and government officials worked to clarify the scope and implications of the order.
The episode has raised broader questions about how the US government decides when advanced AI systems pose sufficient risk to warrant export restrictions, and who has authority over those decisions. Reporters have noted the incident highlights the growing tension between AI development timelines and regulatory processes not designed to move at the same speed.
