PlanarBench: Evaluating LLM Spatial Reasoning via Planar Graph Drawing

Read the original on arXiv AI →

arXiv:2606. 02010v1 Announce Type: cross Abstract: PlanarBench tests whether LLMs can draw planar graphs as ASCII art given only an edge list -- a spatial reasoning task that resists memorization because edge order, edge orientation, and node labels are all permutable.

MathVis: Can AI Reason through Drawing? A Benchmark for Mathematical Figure Generation

MathVis is a new benchmark that tests large language models (LLMs) on their ability to generate and reason with mathematical figures. It contains 512 tasks, each with a mathematical statement, a reference diagram, executable TikZ or SVG code, a gold intermediate representation, atomic rubrics, and error codes. Initial results show that GPT‑6‑Astra, Claude Fable 5, and Gemini 3.1 Pro Preview achieve pass@1 scores of 31.25 %, 26.56 %, and 22.85 % respectively, yet the models tend to produce outputs dominated by formal languages and graphics programs rather than clear, diagram‑mediated reasoning, often resulting in visually confusing solutions for humans.

Solving Is Not Drawing: A Benchmark for Diagrammatic Reasoning in Olympiad Geometry

The paper introduces a new benchmark for diagrammatic reasoning in olympiad geometry, comprising 954 self‑contained problems and a 297‑problem hard subset. Each problem is paired with a human‑authored, high‑fidelity diagram in Asymptote code and a suite of metrics for evaluating diagram construction. Experiments show that current foundation models excel at solving the problems but produce markedly less faithful diagrams, with an average compile success rate of only 36.14%.
