SynthDocBench - Chart Reading: leaderboard
The chart-reading subset of SynthDocBench (ServiceNow, 2026): accuracy in percent on 597 questions about charts and tables inside long synthetic reports read as page images, judged by GPT-5 against deterministic references. Higher is better.
Metric: Accuracy (%) on chart-reading questions: GPT-5 judge scores each answer 0 to 10 against a deterministic reference and an answer counts when the score is at least 6; pages rasterized at 144 DPI in 5-page strips, vision-only input, temperature 0; higher is better.
