Claude Fable 5 & Mythos 5: The Full Return — Safeguards, the Jacobian Conjecture, and the New Frontier Pricing Reality
Claude Fable 5 and Mythos 5 fully restored after 19-day government suspension. Fable 5 now leads SWE-Bench Pro at 80.3%, helped disprove the 87-year-old Jacobian conjecture, and operates with new safety classifiers, fallback routing, and complex pricing. Mythos 5 remains restricted to Project Glasswing. Analysis of the export control saga, new safeguards architecture, benchmark dominance, and what it means for the frontier landscape.
