We need to talk about Fable (I'm angry and you should be too) | Indiehackers

The US government just pulled Claude Fable 5, the most powerful AI model ever released to the public, three days after launch. I think it's the wrong call, and I wrote my dissertation on this exact kind of attack, so let me explain why. On June 12, 2026, an export control directive citing national security suspended access to Fable 5 and Mythos 5 for any foreign national, which forced Anthropic to shut both models down for everyone worldwide. The government's side, laid out by David Sacks, is that it's a fixable jailbreak and the ball is in Anthropic's court. Anthropic's side is that the flaw is narrow and already exists in other models like OpenAI's GPT-5.5. Meanwhile the rest of us are locked out, still waiting on the full details Anthropic promised within 24 hours. Back in 2022 I wrote my computer science bachelor's thesis on extracting AI model parameters through side channel attacks. Basically, hacking AI models. It was awarded best thesis in my cohort. Spending a year on the attacker's side of this exact problem is why I'm convinced that locking these models away from the public is the worst move on the board. You take nothing away from the attackers, who already have what they need. You only disarm the defenders and the researchers who find and patch the holes. And we've run this experiment before: in the 1990s the US classified strong encryption as a munition and tried to lock it down. It failed. You can't uninvent something.
