Just as last week was ending, the US government forced Anthropic to pull its two newest models, Fable 5 and Mythos 5, citing national security concerns after Amazon researchers allegedly found a way to bypass Fable 5’s guardrails. 

Cybersecurity researchers have since signed an open letter calling the move dangerous, and Anthropic itself noted the same jailbreaks exist in other models. So is this a genuine security concern, or just the latest chapter in a messy relationship between Anthropic and the Trump administration? 

On this episode of TechCrunch’s Equity podcast, hosts Anthony Ha, Sean O’Kane, and Rebecca Bellan unpack what the ban means for developers building on Anthropic’s platform and for anyone watching the IPO, why it might accidentally be good for the company, and more of the week’s headlines.
