 ## Overview
-Multimodal Foundation Models (MMFMs) have shown unprecedented performance in many computer vision tasks. However, on some very specific tasks like document understanding, their performance is still underwhelming. In order to evaluate and improve these strong multi-modal models for the task of document image understanding, we harness a large amount of publicly available and privately gathered data (listed in the image above) and propose a challenge. In the following, we list all the important details related to the challenge. Our challenge is running in two separate phases.
