A cheap model nearly matches the frontier at a twentieth the cost

Claim

On CursorBench 3.1 Opus 4.7 Max edged ahead at 64.8% while Cursor's own Composer 2.5 nearly matched it for a twentieth of the cost, and Fable 5 aced a physics-demo gauntlet but billed six times more than Opus 4.8.

Reported metric: 64.8% / 20x cheaper
