PhyX-AF - PhyX Electromagnetism (Image): leaderboard

Multimodal autoformalization into Lean 4 (PhyX-AF; Xiong et al., 2026): 6 PhyX electromagnetism problems whose diagram is given as an image and is needed to state the problem. The model runs as the backbone of the MMFormalizer recursive-grounding framework, and two expert annotators judge whether the resulting formal statement is valid; accuracy in percent, higher is better.

Metric: Human-verified autoformalization accuracy (%; 6 PhyX electromagnetism problems with the diagram as image input, Lean 4 output judged valid by two expert annotators). Source: arxiv.org. Saturation forecast: Around February 2027. 5 models tracked.
