Anthropic Refused White House Demand to Patch Fable 5 Jailbreak Before Export-Control Shutdown

New reporting reveals the export-control shutdown of Claude Fable 5 / Mythos 5 followed Anthropic's refusal to fix a jailbreak: White House AI adviser David Sacks says the administration asked Dario Amodei to patch or de-deploy and he declined, after Amazon red-teamers bypassed guardrails by having the model 'read a codebase and identify flaws.' Anthropic reportedly had ~90 minutes to restrict access before Commerce invoked national-security export controls over fears of Chinese access; the models remain offline (Day 9) with refund and free-trial deadlines lapsing this week. Builders depending on Fable 5 should plan fallbacks — and note the irony that a code-analysis capability triggered the ban.
