- simonw 27d agoIt's common for models to produce a draft of the SVG part way through their reasoning. Here's Qwen3.8-Flash-Next doing that, for example: https://tools.simonwillison.net/markdown-svg-renderer#url=https%3A%2F%2Fgist.github.com%2Fsimonw%2F6ba7cbfc1a9336986703b41f7fccd73a https://tools.simonwillison.net/markdown-svg-renderer#url=ht... The open weight models let you see the full reasoning trace. Models from OpenAI, Anthropic, and Gemini tend to obscure or summarize the reasoning traces so you can't see exactly what they're doing. Here's Gemini 3.7 Flash which looks like it's doing something similar: https://tools.simonwillison.net/markdown-svg-renderer.html#url=https%3A%2F%2Fgist.github.com%2Fsimonw%2F6779a22d5e7bb6bdf29936f1600a5259 https://tools.simonwillison.net/markdown-svg-renderer.html#u... One of the step summaries includes this: > I'm now detailing the pelican's anatomy within the SVG. I've sketched the main body outline, including coordinates for the tail, chest, neck, head, and massive beak with a pouch. I'm focusing on the position of the eyes and considering the positioning of the wings, with the foreground wing on the handlebar for a confident look.
