US Blocks Anthropic Fable 5 Release, But Market Numbers Keep Running
AI News Flash: Last weekend, the US government forced Anthropic to delist its two latest models Fable 5 and Mythos 5, citing national security as the reason. The direct trigger was Amazon researchers reportedly discovering a method to bypass Fable 5’s safety guardrails, prompting government intervention. Following the incident, multiple cybersecurity researchers signed an open letter, criticizing the government’s move as counterproductive and even more dangerous. Anthropic also pointed out that the same jailbreak technique isn’t unique to Fable 5—other mainstream models have similar vulnerabilities—implying the logic behind the selective delisting is hard to justify.
