CADBench: 10 models tested on 105 Fusion 360 tasks, best pass rate only 24.6%

Seldon released CADBench, evaluating 10 models on 105 realistic CAD tasks in Fusion 360. Fable 5 and Gemini 3.7 Flash tie for #1 with only a 24.6% pass rate.

The notable signal: the co-leader is Gemini 3.7 Flash, not a frontier-tier model — the gap between "best" and "cheapest-good-enough" for computer-use CAD is already near zero, changing who gets to build in Fusion 360. A benchmark worth watching for how close agents are to building physical things.
