LitXBench - Configurations: leaderboard
Metric: Configuration F1 (0-1), whether the right microstructure configurations (phases and sub-regions) are extracted for extracting every experiment (materials, process chains, microstructure configurations and measurements) as Python objects from the OCR text of LitXAlloy's 19 alloy papers (1,426 measurements; figures excluded), extracted materials matched to the annotated ones by the Hungarian algorithm, mean of three runs; models called through the API with Pydantic AI; higher is better. Source: arxiv.org. Saturation forecast: Around August 2027. 6 models tracked.
