FysicsReason: Benchmarking Verifiable World-State Reasoning Across Omni-Modalities

🏠 Project Page    📖 Paper    🤗 Dataset   

Dataset Overview

FysicsReason is a five-task omni-modal benchmark designed to evaluate physical reasoning across images, audio, video, and text. The benchmark contains five complementary tasks that cover visual understanding, audio-visual grounding, temporal reasoning, physical property comparison, and quantitative physical inference. Each task is provided as a separate Parquet file under task{1..5}/, together with its associated media files.

Task Composition

Task	Samples	Input	Prediction Target
task1	562	Image and text question	Target quantity and final answer
task2	779	Image, scene audio, and text question	Object bounding box and answer option
task3	250	Video and multiple-choice text question	Evidence interval and answer option
task4	350	Two object images, object audio, and text question	Property, materials, and selected object
task5	387	Video and text question	Physical property and numerical answer

Data Organization

Media paths stored in the Parquet files are relative to the dataset root. For example: data/task2/media/... When loading the dataset locally, these paths should therefore be resolved relative to the directory containing the data/ folder. Each task directory contains its corresponding annotation file and linked media resources, allowing the benchmark to be used directly for task-specific or unified omni-modal evaluation.

Sample Identification

The index field serves as the stable, zero-based row identifier within each task. For evaluation and result submission, a sample can be uniquely identified using the combination of:

• task_source
• index This convention provides a consistent mapping between dataset samples and inference outputs.

Evaluation

Inference results produced on FysicsReason can be evaluated using the official workflow provided in the FysicsReason repository. FysicsReason Evaluation Repository
