Side-by-side evidence
Seventeen verified runs: the two launch specimens plus a frozen three-prompt matrix across five hosted model endpoints or quality tiers.
Strong owl, navy enamel, brass, key, and art-deco fan adherence. Spectacles are round rather than half-moon. Exposed gears are plausible but not a demonstrably complete functional train.

Grok Imagine and all three GPT Image 2 tiers rendered the exact seven-object spatial scene; MiniMax Image-01 produced ten objects. Grok and all three GPT tiers rendered the requested two-line poster text exactly; MiniMax added a third pseudo-text line. On Herman identity, GPT Image 2 Medium led the visual review at 9.5/10, followed by High at 9.2, Low at 8.8, Grok at 8.6, and MiniMax at 6.4. These are single unseeded trials, not statistical rankings.
