In the realm of large multi-modal models (LMMs), efficient modality alignment is crucial yet often constrained by the scarcity of high-quality image-text data. To address this bottleneck, we introduce the ShareGPT4V dataset, a pioneering large-scale resource featuring 1.2 million highly descriptive captions, which surpasses existing datasets in diversity and information content, covering world knowledge, object properties, spatial relationships, and aesthetic evaluations. Specifically, ShareGPT4V originates from a curated 100K high-quality captions collected from advanced GPT4-Vision and has been expanded to 1.2 million with a superb caption model trained on this subset. ShareGPT4V first demonstrates its effectiveness for the Supervised Fine-Tuning (SFT) phase, by substituting an equivalent quantity of detailed captions in existing SFT datasets with a subset of our high-quality captions, significantly enhancing the LMMs like LLaVA-7B, LLaVA-1.5-13B, and Qwen-VL-Chat-7B on the MME and MMBench benchmarks, with respective gains of 222.8/22.0/22.3 and 2.7/1.3/1.5. We further incorporate ShareGPT4V data into both the pre-training and SFT phases, obtaining ShareGPT4V-7B, a superior LMM based on a simple architecture that has remarkable performance across a majority of the multi-modal benchmarks. We will release this project to serve as a pivotal resource for advancing the LMMs community.

ShareGPT4V Dataset (100K)

Dataset Name Image Source Visible Captioned by Samples Avg.
COCO-Caption COCO ✔︎ Human 118K 52
LLaVA-23K COCO GPT4 23K 609
ShareGPT4V LCS, COCO, etc. ✔︎ GPT4-Vision 100K 942
ShareGPT4V-PT LCS, COCO, etc. ✔︎ Share-Captioner 1,246K 826

Comparison of widely-used caption datasets and ShareGPT4V. 'LCS' abbreviates the LAION, CC, and SBU datasets. The 'Visible' column denotes the image visibility during captioning, and the 'Avg.' column shows the average character number of the caption.

We illustrate the procedure for collecting highly descriptive captions from GPT4-Vision via various image sources and data-specific prompts, resulting in 100K high-quality captions that encapsulate a wide array of information conveyed by the images.

A comparison between the caption in our proposed ShareGPT4V dataset and those utilized by recent large multi-modal models (LMMs):

ShareGPT4V-PT Dataset (1.2M)

We delineate the process of utilizing the seed captions to train a general captioner (Share-Captioner) and then employing this captioner to generate 1.2M high-quality captions for pre-training usage.
