- SPM-Bench establishes a paradigm for automated scientific data synthesis in specialized domains
📖 Full Retelling
A team of researchers led by Peiyang Xiao and 12 other authors introduced SPM-Bench, a novel PhD-level multimodal benchmark specifically designed for evaluating large language models in scanning probe microscopy, on February 26, 2026, through an arXiv publication, addressing significant gaps in existing benchmarks that suffer from data contamination, insufficient complexity, and prohibitive human labor costs in specialized scientific domains. The researchers developed a fully automated data synthesis pipeline that ensures both high authority and low-cost benchmark creation, employing Anchor-Gated Sieve technology to efficiently extract high-value image-text pairs from arXiv and journal papers published between 2023 and 2025. A key innovation is their hybrid cloud-local architecture where vision language models return only spatial coordinates 'llbox' for local high-fidelity cropping, achieving extreme token savings while maintaining high dataset purity. To accurately evaluate LLM performance, the researchers introduced the Strict Imperfection Penalty F1 (SIP-F1) score, which establishes a rigorous capability hierarchy and, for the first time, quantifies model 'personalities' as Conservative, Aggressive, Gambler, or Wise. By correlating these results with model-reported confidence and perceived difficulty, the research exposes the true reasoning boundaries of current AI in complex physical scenarios, positioning SPM-Bench as a generalizable paradigm for automated scientific data synthesis that could be applied to other specialized domains beyond scanning probe microscopy.

Here we present SPM-Bench, an original, PhD-level multimodal benchmark specifically designed for scanning probe microscopy . We propose a fully automated data synthesis pipeline that ensures both high authority and low-cost. By employing Anchor-Gated Sieve technology, we efficiently extract high-value image-text pairs from arXiv and journal papers published between 2023 and 2025. Through a hybrid cloud-local architecture where VLMs return only spatial coordinates "llbox" for local high-fidelity cropping, our pipeline achieves extreme token savings while maintaining high dataset purity. To accurately and objectively evaluate the performance of the LLMs, we introduce the Strict Imperfection Penalty F1 (SIP-F1) score. This metric not only establishes a rigorous capability hierarchy but also, for the first time, quantifies model "personalities" (Conservative, Aggressive, Gambler, or Wise). By correlating these results with model-reported confidence and perceived difficulty, we expose the true reasoning boundaries of current AI in complex physical scenarios. These insights establish SPM-Bench as a generalizable paradigm for automated scientific data synthesis. Subjects: Artificial Intelligence (cs.AI) Cite as: arXiv:2602.22971 [cs....
