The US government forced Anthropic to pull its Fable 5 and Mythos 5 models over national security concerns following reports of bypassed guardrails. Critics argue the action may backfire.

The forced removal came after Amazon researchers identified a method to circumvent Fable 5's safety guardrails. The government cited national security risks as justification for the ban. However, the move has drawn swift pushback. A group of cybersecurity researchers published an open letter opposing the decision, while Anthropic noted that similar jailbreaks exist across competing AI models from other developers. The contradiction highlights a potential unintended consequence: the ban may boost Anthropic's brand among users skeptical of government intervention in AI development. The controversy has generated significant media attention, casting Anthropic as a victim of regulatory overreach rather than a security liability. The incident raises questions about the effectiveness of selective bans when vulnerabilities aren't unique to targeted products. Industry observers note that inconsistent enforcement could drive users toward banned models through alternative channels, ultimately undermining the government's security objectives.
