Claude Fable 5.5 needs a 70 on AA index to justify replacing Opus 5.5
haider1 · x · 2026-11-09
Commenting on the Artificial Analysis Intelligence Index v5.0.1 chart, haider1 argues the projected Claude Fable 5.5 (70, not yet measured) must be significantly better than Opus 5.5 to be worth using, since Opus 5.5 (max) already scores 59 — 58 with fallback — and handles almost anything. The chart also lists Gemini 4 Carbon (high) at 60, GPT-6 at 57, GPT-6.1 and Claude Sonnet 5.5 at 55. If gaps get this large, he wonders how much longer humans can keep up.
