kevinkern · x · 2026-09-24

Kevin Kern reran his Audi Quattro benchmark — giving multiple models the same reference image to model in Blender, with and without skills and review rounds — adding Claude Opus 5.5 and GPT-6 Sol. The comparison spans GPT-6 Astra/Sol, Opus 5.5, Fable 5.1, Grok 4.6, GLM 5.3 and Tencent Hy4, viewable per-car or side by side.

His verdict: only GPT-6 Astra and Opus 5.5 are worth taking seriously, ranked gold for Astra and second for Opus 5.5 based on visual detail and reference fidelity; Grok, GLM and Hy4 trail visibly after round one.
