Claude Fable 5 was available to the public for only a few days before Anthropic pulled it offline. Not because of a normal product rollback, not because capacity ran out, and not because the company changed its mind about pricing. Anthropic says the US government issued an export-control directive requiring it to suspend access to Fable 5 and Mythos 5 for any foreign national, including foreign-national Anthropic employees, and the company disabled both models for everyone in order to comply.
