Researchers have developed a new method for visual document understanding that bypasses the need for coordinate-based region labels. By comparing a coordinate interface with a text-based quote-and-retrieve pipeline, they found that the latter significantly improved evidence recall and reduced hallucination rates across multiple vision-language models. This approach, which uses a GRPO recipe to train models to quote better evidence without costly region-level supervision, demonstrated an increase in strict attributed accuracy for an 8B backbone model.
