Title: StructEval: Benchmarking LLMs' Capabilities to Generate Structural Outputs

Abstract:
arXiv:2505.20139v3 Announce Type: replace-cross Abstract: As Large Language Models (LLMs) become integral to software development workflows, their ability to generate structured outputs has become critically important. We introduce StructEval, a comprehensive benchmark for evaluating LLMs' capabilities in producing both non-renderable (JSON, YAML, CSV) and renderable (HTML, React, SVG) structured formats. Unlike prior benchmarks, StructEval systematically evaluates structural fidelity across div
