When a document image states multi-step selection constraints in narrative text and the supporting numbers sit in several charts, multimodal models degrade steadily as either the number of logical hops (2 to 5) or the number of charts (2 to 6) grows, with the best model reaching 62.83% overall against over 90% for human annotators.

Capability: Carrying a chain of inference through to its conclusion

Observed on

Synthetically generated single-page document images with interleaved charts and narrative; questions grounded on a semantic label rather than named entities; 2,074 examples, six ta.

Sources

  • Measured over 2,074 generated instances with programmatic answer verification plus human checks of narrative and rendering; depth/chart trends reported for two reasoning models only (GPT-5.2 Reasoning, Gemini-2.5-Pro Reasoning). Synthetic and out-of-domain by the authors' own framing, so absolute numbers may not transfer to real documents; the design does not separate chart OCR errors from reasoning errors, and the qualitative cases show both.

Notes

Drafted from the paper by a model and filed unreviewed. Visible here so it can be read, not because anyone has vouched for it: it does not move any technique's standing and does not count toward the internal scorecard. Drafted confidence: medium. Falsifier as drafted: A model whose accuracy on these items stays flat or rises as reasoning depth goes from 2 to 5 and chart count from 2 to 6, or a frontier model matching the >90% human rate on the full set.
