The White House restricted access to Anthropic's Mythos AI model and its consumer version Fable 5, reportedly over concerns that a China-linked group may have gained access. Anthropic said the White House did not raise the issue before the restrictions and that it bans use of its products from China.
The White House is now reported to have separately restricted access to Anthropic's Mythos model and its consumer version Fable 5, according to unnamed sources who told an outlet that the move was driven by concerns that a China-linked group may have gained unauthorized access. Anthropic said the White House did not raise this concern with the company before the restrictions and reiterated that it already bans use of its products from China.
The new report joins a chain of events The Zioneer has been tracking since 06:31 Jerusalem on June 13, when the US government first ordered Anthropic to block the models for foreign users citing national security. Within hours, Anthropic announced a full global suspension of both Fable 5 and Mythos 5, stating it could not technically enforce a citizenship-only ban (reported at 06:31 and updated at 18:32 Jerusalem). Later that evening, at 20:56 Jerusalem, the Wall Street Journal reported that talks between Amazon's CEO and US officials had led to the blocking of the models. The latest report appears to describe a distinct government action adding a China-access restriction — rather than the earlier suspension — though the sources do not clarify the legal or technical relationship between the two.
As The Zioneer reported, the models were initially flagged over concerns they could be jailbroken to bypass safety mechanisms and were cited for cyber vulnerability and potential biological weapon development risks. Anthropic has argued that the vulnerability in question is a narrow code-analysis scenario already present in other public models.
What remains unconfirmed: the identity of the China-linked group said to have accessed the model, the specific technical restriction the White House imposed, and whether this action is an expansion of or separate from the prior US order.
