For anyone who followed yesterday's Gemini 3.7 Flash pelican which rendered in Safari but not in Firefox or Chrome... https://news.ycombinator.com/item?id=49289112#49290012 . - that turned out to be my fault, not the model. My SVG rendering software was stripping some attributes. Here's the Gemini 3.7 Flash pelicans in the fixed renderer: https://tools.simonwillison.net/markdown-svg-renderer.html#u...
Perhaps this isn’t a new observation but the problem with LLMs is very clear with these. It’s a nice microcosm. The LLM will draw a fish companion (unprompted!) with a nice gradient but won’t get the pelican’s feet right. It’s obviously a problem of fundamental understanding and demonstrates that reasoning is more “directionless rigour”.
Besides which, "fundamental understanding" isn't a binary. Humans can also have a deep understanding of a subject and still make errors. (I do, anyways.) I do not think "fundamental understanding" is itself well enough understood to say definitively that LLMs do or do not have it.
*Some models have multimodal capabilities but these are separate weights, I believe it's only engaged in processing images. From the reasoning trace, the model never rendered the result -- only instructed the user to do so. I welcome correction if I'm wrong, I only have a surface-level understanding here.
