Frontier Model Index Compressed to 2 Points. That Makes Pricing and Ecosystem the Only Moats Left.

The Artificial Analysis Intelligence Index shows extreme compression. Claude Opus 5.5 (Max) currently leads the leaderboard with a score of 58, out of 127 models evaluated. Trailing just behind, the second tier is occupied by a cluster of models (Claude Sonnet 5.5 (Max), Claude Opus 5.5 (Xhigh), and the newly arrived Muse Wonder Full (Max)) all sitting at 56. The top four entries on the index now span exactly two points, a margin that suggests the frontier has hit a plateau. \n\n This snapshot is not a stable convergence. Week-to-week movement at a two-point spread can easily be noise.
