# chartqa: 500-sample lite benchmark

500 evaluation examples sampled with seed **42**. Sampling: uniform random rows without replacement.

## Sources and attribution

- [lmms-lab/ChartQA](https://huggingface.co/datasets/lmms-lab/ChartQA/tree/9e63b7df1592a1c2158e735cc1725454aef0d6d9), revision `9e63b7df1592a1c2158e735cc1725454aef0d6d9`.

Original dataset and source-image terms apply; this subset does not relicense them. See the linked upstream datasets for their license and citation information.

## Reproducibility

`subset.json` records the pinned sources, selected source indices, decoded-image/label hashes, native task configurations, seed, and sampling procedure. `_lite_source_index` and `_lite_task_id` identify each example in its prepared source split. Image bytes are embedded in the Parquet files; no cluster paths are required. Original pixels, questions, reference labels, and scoring fields are preserved.

This is an evaluation subset. Its scores are not full-benchmark scores. Use the native benchmark metrics from [foveated_vlm](https://github.com/Gabesarch/foveated_vlm). This benchmark uses automatic scoring.
