CrystalXRD-Bench: Benchmarking Vision-Language Models for XRD Peak Indexing Across Diverse Crystalline Materials
arXiv:2605.29446v1 Announce Type: new Abstract: Miller-index identification from powder XRD patterns requires capabilities untested by existing multimodal benchmarks: the model must read a narrow peak location from a rendered scientific curve and then connect that observation to multi-step crystallographic reasoning. We introduce CrystalXRD-Bench, a 250-sample benchmark built from 10 public crystallographic databases for a single task: recover the full set of HKLs contributing to the highest-intensity peak in an XRD pattern. Each sample pairs the rendered XRD image with the source CIF text and
The proliferation of advanced AI models and the increasing demand for materials discovery and understanding in various industrial and scientific fields drive the need for specialized benchmarks.
This benchmark allows for the rigorous evaluation and development of vision-language models in a critical scientific domain, potentially accelerating materials science research and industrial innovation.
Vision-language models can now be specifically tested and improved for their ability to interpret complex scientific imaging data alongside textual information for material characterization.
