Analysis: Anthropic refuses to fix the Fable jailbreak vulnerability, leading the U.S. government to implement export controls

David Sacks, the head of AI and crypto affairs at the White House, stated that although the commercial version of the Mythos series model Fable released by Anthropic this week includes safety barriers, once those barriers are bypassed, users will be able to access Mythos's advanced cyber attack capabilities. Sacks pointed out that Anthropic had previously described Mythos as a "cyber weapon" that requires regulation, so fixing the related vulnerabilities should have been its responsibility.

Sacks mentioned that a partner trusted by both Anthropic and the U.S. government discovered a jailbreak method to bypass the safety barriers while testing Fable. The U.S. government subsequently requested Anthropic CEO Dario Amodei to fix the vulnerabilities or take the model offline, but this request was refused. Anthropic stated in a declaration that the vulnerability is "not serious," a claim that contradicts the judgment of the U.S. government and relevant partners.

Sacks stated that Anthropic has always emphasized that safety should be prioritized, but this time it prioritized maintaining consumer-grade model services. In response, the U.S. government reluctantly imposed export control measures on Anthropic and hopes that Anthropic will resolve the safety issues as soon as possible to lift the related restrictions and restore the full release of Fable.

Sacks also denied that this action is related to previous disputes between the U.S. Department of Defense and Anthropic, stating that the government recognizes Anthropic's technological capabilities and believes that the current issues can be resolved relatively easily, with the initiative currently in Anthropic's hands.
