GPT Astra High Shows Best-Ever 3D Understanding in 40-Minute Sculpting Test
rms80 · x · 2026-09-05
A cited hands-on test shows GPT Astra High sculpting 3D in a custom C++ app over 40 minutes, recording 467 brush strokes and 25 undos—described as the best 3D spatial understanding to date. Aesthetic proportions still trail Fable/Opus 5, and it's not yet competitive with professional Zbrush artists (estimated two model generations away). Commenters note this tests true 3D perception better than Blender/CAD, where math and rules can sidestep it.
