Researchers have introduced AmbiHTMLBench, a new benchmark designed to evaluate models on their ability to parse visually rich documents and reconstruct them into executable HTML. Unlike traditional systems that output Markdown, AmbiHTMLBench focuses on HTML to better preserve spatial structure, visual hierarchy, and rendering semantics. The benchmark includes 1,115 diverse pages with structured annotations and uses both objective metrics and human-aligned subjective evaluations to assess model performance. Initial tests on ten multimodal systems showed varying results between objective and subjective assessments, highlighting the need for task-specific adaptation, which was demonstrated by fine-tuning a small-parameter expert model.
