AppleSO-Bench: A Structural Output Evaluation of Multimodal LLMs
Read Full ArticleSummary
The article presents SO-Bench, a benchmark designed to evaluate the structural output capabilities of multimodal large language models (MLLMs) across various visual domains. It highlights the importance of schema-grounded information extraction and reasoning, addressing the gaps in current models' abilities to generate schema-compliant outputs. The benchmark consists of over 6.5K diverse JSON schemas and 1.8K curated image-schema pairs, emphasizing the need for improved multimodal structured reasoning. The authors also detail a multi-stage data generation pipeline that incorporates human verification and advanced models like GPT-5 and Gemini-2.5-Pro to enhance the quality of the generated data.
