Multimodal & Grounded benchmark
CharXiv (overall) leaderboard
CharXiv Descriptive and Reasoning Combined. Every model the catalog carries a published CharXiv (overall) value for, ranked by that value.
A scientific chart understanding benchmark scored across both the descriptive and reasoning splits rather than the reasoning split alone.
CharXiv (overall) ranking
1 model with a published CharXiv (overall) value, ordered by that value, highest first. Models the source has not scored on this benchmark are not listed — they are unmeasured, not last.

Evidence key: Observed
Rows are ordered by the value CharXiv: Charting Gaps in Realistic Chart Understanding in Multimodal LLMs published, highest first. The source does not state whether a higher value is the better result, so this page does not either: for a benchmark that measures a rate of failure, read the table from the bottom.
