To evaluate the performance of different LLMs, we utilized the refined CSD MOF Subset, building on prior work . To ensure consistency and facilitate meaningful comparisons across LLMs, we randomly selected 50 Digital Object Identifiers (DOIs) from this subset for each specific task: synthesis condition extraction, single-hop Q&A generation, and multi-hop Q&A generation. The number of the selected DOIs for each task can be found in the Supporting Information (Table ).
