Introduction

MMMU

MMMU is a new benchmark designed to evaluate multimodal models on massive multi-discipline tasks demanding college-level subject knowledge and deliberate reasoning. MMMU includes 11.5K meticulously collected multimodal questions from college exams, quizzes, and textbooks, covering six core disciplines: Art & Design, Business, Science, Health & Medicine, Humanities & Social Science, and Tech & Engineering. These questions span 30 subjects and 183 subfields, comprising 32 highly heterogeneous image types, such as charts, diagrams, maps, tables, music sheets, and chemical structures. Unlike existing benchmarks, MMMU focuses on advanced perception and reasoning with domain-specific knowledge, challenging models to perform tasks akin to those faced by experts. Our evaluation of 14 open-source LMMs and the proprietary GPT-4V(ision) highlights the substantial challenges posed by MMMU. Even the advanced GPT-4V only achieves a 56% accuracy, indicating significant room for improvement. We believe MMMU will stimulate the community to build next-generation multimodal foundation models towards expert artificial general intelligence (AGI).

MMMU-Pro

Building upon MMMU, MMMU-Pro introduces even more stringent assessment methodologies to evaluate multimodal models' intrinsic understanding and reasoning capabilities. MMMU-Pro employs a meticulously structured three-step process:

Filtering out text-only answerable questions: Ensures that the questions pressing multimodal understanding rather than purely textual comprehension.
Augmenting candidate options: Introduces additional plausible options to make the task more challenging.
Vision-only input setting: Embedding questions within images pushes AI to "see" and "read" simultaneously, replicating a core human cognitive skill of integrating visual and textual information.

Our results reveal that model performance on MMMU-Pro is significantly lower than on MMMU, with accuracies ranging from 16.8% to 26.9% across various models. We investigate the effects of OCR prompts and Chain of Thought (CoT) reasoning. OCR prompts have minimal impact, while CoT generally enhances performance. MMMU-Pro offers a more rigorous evaluation framework, closely reflecting real-world scenarios and providing critical insights for advancing multimodal AI research.

Dataset Creation

MMMU and MMMU-Pro were meticulously designed to challenge and evaluate multimodal models with tasks demanding college-level subject knowledge and complex reasoning. For more detailed information, please refer to our Hugging Face datasets:

Evaluation

Please refer to our evaluation folders for detailed information on evaluating with both MMMU and MMMU-Pro benchmarks:

🎯 MMMU Evaluation

We have released a full suite comprising 150 development samples and 900 validation samples. However, the 10,500 test questions are available without their answers.
Use the development set for few-shot/in-context learning.
Use the validation set for debugging models, selecting hyperparameters, and quick evaluations.

The answers and explanations for the test set questions are withheld. You can submit your model's predictions for the test set on EvalAI.
