opendatalab/ChartVerse-RL-40K

ChartVerse-RL-40K is a curated dataset of the most challenging chart reasoning samples for Reinforcement Learning, developed as part of the opendatalab/ChartVerse project. For more details about our method, datasets, and full model series, please visit our Project Page. This dataset contains samples with the highest failure rates — the most difficult samples that strong VLMs struggle with but can still solve occasionally. These samples provide the strongest learning signal for RL training.… See the full description on the dataset page: https://huggingface.co/datasets/opendatalab/ChartVerse-RL-
