When you squeeze a webpage, do the boxes move in a pattern?
Sep 2026
I wanted to know if a webpage has any physics. When you make the window narrower, do the boxes move in a pattern a model can learn, or is every page a mess? I measured 3,056 boxes on 25 pages. A one-line CSS rule beat a simple linear model. A tree model beat the rule. Median error went from 26.7 pixels to 7.3.

Teach the steps, not the last number

NVIDIA Nemotron reasoning. Each puzzle hides a tiny program. I fitted that program, wrote gold step-by-step traces from it, then LoRA-tuned Nemotron-3-Nano. Public 0.704, private 0.720. Rank 2588 of 4182.

AIMO Progress Prize 3. I ran gpt-oss on a local vLLM server with Harmony prompts, and I had a Qwen2.5-Math pipeline next to it. Private 38.5. Rank 2345 of 4138.
