My personal AI benchmark: "Generate an SVG of a frog with a Habsburg jaw."

Anthropic's Claude Opus 5 successfully generated an SVG of a frog with a Habsburg jaw, including anatomical annotations such as 'massive protruding mandible' and 'recessed, tucked behind the jaw' for the upper lip, demonstrating the model's ability to interpret and render specific biological features in code.

The annotations are mostly structural labels, but include some editorializing about the jaw feature: "massive protruding mandible" and describing the upper lip as "recessed, tucked behind the jaw" and lower teeth as "protruding" over the upper lip, which offer anatomical interpretation beyond plain labeling.

The annotations mostly use structural labels, but include editorializing on exaggerated anatomy ("HUGE protruding Habsburg jaw," "lower teeth jutting over the upper lip") and implied royal bearing/mood via "droopy regal eyelids."

The annotations are largely structural labels, but include some editorializing on anatomical effect, notably describing the jaw as "massive elongated protruding mandible" and the mouth as "underbite mouth: receded upper lip, protruding lower lip" — emphasizing exaggerated deformity beyond a neutral label. No commentary on mood, royalty, or bearing is present beyond the literal "HABSBURG JAW" label itself.
