Scatter chart on a dark background: two lines of five points each, one for GPT-6 Sol and one for Claude Opus 5.5, plotting Artificial Analysis Intelligence Index score against cost per task on a log scale from low to max effort. Sol runs from 34 points at $0.13 to 47.5 at $1.06; Opus 5.5 runs from 42 points at $0.55 to 57.6 at $5.98. The two lines overlap only between about 42 and 47.5 points.

Hand-drawn ink illustration: a brass balance scale on a workbench. One pan holds a single plain block, the other a tall stack of many identical thin sheets; the beam is very nearly level. A small yellow brass weight lies on the bench beside the scale, off both pans, with a hand reaching toward it.
