PhyDrawGen: Physically Grounded Diagram Generation from Natural Language

In three linesPhyDrawGen is a neuro-symbolic pipeline generating physics diagrams from text while respecting physical laws. An LLM extracts a typed scene graph, a deterministic solver converts it to a planar straight-line graph, and Qwen-VL fine-tunes a propose-verify loop. Evaluated on 1,449 problems (mechanics, optics, electromagnetism), it outperforms GPT-5-image and Gemini.
