LongDS v1 - Business: leaderboard

LongDS (Xu et al., Zhejiang University and Ant Group, EMNLP 2026) long-horizon data-analysis tasks built from Kaggle notebooks, in which later turns update, perturb, roll back or combine analytical states set up many turns earlier. A ReAct agent writes Python in a persistent Jupyter kernel (DSGym, up to 40 steps per turn) and a DeepSeek-V4-Pro judge checks each turn against executable reference code. The score is per-task turn accuracy macro-averaged over the 12 business tasks of the original v1 release, in percent; higher is better.

Metric: Accuracy (%; macro-average over 12 business tasks of per-task turn accuracy; DSGym ReAct agent in a persistent Jupyter kernel, up to 40 steps per turn, DeepSeek-V4-Pro judge). Source: arxiv.org. Saturation forecast: Around June 2027. 5 models tracked.
