做视觉生成模型训练的研究者终于有了一个大规模、开放许可、可直接商用的数据集，不用再为版权和合规问题头疼。建议做图像生成、扩散模型或流匹配的团队直接下载使用。
斯坦福大学发布GPIC（Giant Permissive Image Corpus），一个包含约28万亿像素、1亿训练样本的开放许可图像数据集。所有图像均采用宽松许可，可自由用于研究和商业用途，并经过安全过滤和去重处理。数据集托管在Hugging Face上，附带基准测试协议和像素空间流匹配的参考基线。这为视觉生成模型的可扩展研究提供了稳定、大规模且合规的数据基础。
GPIC: A Giant Permissive Image Corpus for Visual Generation
Studying scalable methods for visual generative modeling requires large, accessible, and stable datasets. We introduce GPIC, a Giant Permissive Image Corpus of approximately 28 trillion pixels. GPIC comprises diverse internet images captioned by a state-of-the-art vision-language model, including 100M training, 200K validation, and 1M test examples. Moreover, all GPIC images are permissively licensed for both research and commercial use. GPIC is safety-filtered, deduplicated, and centrally hosted on Hugging Face. We provide a benchmarking protocol for generative modeling on GPIC. Finally, we provide a reference baseline for pixel-space flow matching on GPIC. Our dataset, benchmark, and models are available at https://huggingface.co/datasets/stanford-vision-lab/gpic. Evaluation toolkit and code are available at https://gpic.stanford.edu
