the frontier model just became a mid-tier price point. anthropic's claude opus 5.5, released on september 22, matches the flagship fable 5.1 on most work while costing 40 percent less to run, scoring 57.8 percent on cursorbench 4.0 against fable's 51.8 and completing a 680,000-line code migration in a single pass. the expensive model is now the one you keep for emergencies.
