Abstract
image Continue-pretraining, and Multi-task Finetuning. DocOwl2 sets a new state-of-theart across multi-page document understanding benchmarks and reduces first token latency by more than 50%. Compared to single-image MLLMs trained on similar data, our DocOwl2 achieves comparable single-page understanding performance with less than 20% of the visual tokens. Our codes, models, and data are released at https://github.com/X-PLUG/ mPLUG-DocOwl/tree/main/DocOwl2 .
