LMArena reports that Claude Opus 5.5 (High) debuted at #1 in Text Arena with 1509 points, an 18-point jump over Opus 5 (High), now at #11; Opus 4.6 (High) holds #2 just 4 points off the lead, giving Anthropic all six top spots. Opus 5.5 (High) also landed on the Text Arena Pareto frontier at a blended $16/MToken.
In the quoted context, the author echoes the view that Anthropic is betting on code to solve everything, showing how he got Opus 5.5 to build a cheetah from pure code and math: signed distance fields, smooth unions, procedural spots and fur.
