LLM SVG Generation Benchmark

Here's a delightful project by Tom Gally, inspired by my pelican SVG benchmark. He asked Claude to help create more prompts of the form Generate an SVG of [A] [doing] [B] and then ran 30 creative prompts against 9 frontier models - prompts like "an octopus operating a pipe organ" or "a starfish driving a bulldozer".

Here are some for "butterfly inspecting a steam engine":

Gemini 3.0 Pro Preview drew the best steam engine with nice gradients and a butterfly hovering near the chimney. DeepSeek V3.2-Exp drew a floating brown pill with a hint of a chimney and a butterfly possibly on fire. GLM-4.6 did the second best steam engine with a butterfly nearby. Qwen3-VL-235B-A22B-Thinking did a steam engine that looks a bit like a chests on wheels and a weird purple circle.

And for "sloth steering an excavator":

Claude Sonnet 4.5 drew the best excavator with a blobby sloth driving it. Claude Opus 4.5 did quite a blocky excavator with a sloth that isn't quite recognizable as a sloth. Grok Code Fast 1 drew a green alien standing on a set of grey blocks. Gemini 2.5 Pro did a good excavator with another blobby sloth.

It's worth browsing the whole collection, which gives a really good overall indication of which models are the best at SVG art.
