Imagenet21K_RecaptionThis dataset is the entire 21K ImageNet dataset with about 13 million examples and about 19 thousand classes as strings
(for some reason it only had ~19K classes instead of 21K).
If you want an even larger set of images, I have a recaptioned CC12M and ImageNet dataset: https://huggingface.co/datasets/gmongaras/CC12M_and_Imagenet21K_Recap
The images are in PNG format. They can be decoded like in the following example

from PIL import Image
Image.open(io.BytesIO(row["image"]))

CC12M WebDataset with COCO-style Recaptions
A large-scale image-text dataset containing 3 million images from Conceptual Captions 12M (CC12M) with COCO-style factual descriptions generated using NVIDIA Nemotron Nano 12B v2 VL.
Dataset Overview
Base Dataset: pixparse/cc12m-wds - Conceptual Captions 12M (CC12M)
Images: 3,000,000+ high-quality internet images
Recaption Model: NVIDIA Nemotron Nano 12B v2 VL
Recaption Style: COCO-style factual descriptions (20 words average)… See the full description on the dataset page: https://huggingface.co/datasets/undefined443/cc12m-wds-coco-recaptioned.Stable_Diffusion_3_RecaptionThis dataset is the one specified in the stable diffusion 3 paper which is composed of the ImageNet dataset and the CC12M dataset.
I used the ImageNet 2012 train/val data and captioned it as specified in the paper: "a photo of a 〈class name〉" (note all ids are 999,999,999)
CC12M is a dataset with 12 million images created in 2021. Unfortunately the downloader provided by Google has many broken links and the download takes forever.
However, some people in the community publicized the dataset.… See the full description on the dataset page: https://huggingface.co/datasets/gmongaras/Stable_Diffusion_3_Recaption.wikiart_recaptionWikiArt Dataset captioned using vikhyatk/moondream2 model with prompt : Generate a short, simple and only visually descriptive caption for this image.
COCONut-PanCap-Recaptioned
COCONut-PanCap Re-captioned (train2017)
Regenerated captions for the train2017 split of COCONut-PanCap
(paper,
dataset).
The released captions contain phrases bound to the wrong segment, references to objects that
are not in the image, redundant restatements, and untagged summary sentences that carry no
grounding. We regenerated every caption and repaired the remaining errors, keeping the file
layout of the original release.
Only the caption text changed. Mask ids… See the full description on the dataset page: https://huggingface.co/datasets/Panorama-grounding/COCONut-PanCap-Recaptioned.wit_1m_recaptioned

DaTikZ-v3 Recaptioned
A 10,000-sample subset of DaTikZ-v3 with captions regenerated using Gemini Flash via vision-language captioning.
Captioning
Original captions were replaced by passing each rendered diagram image to Gemini Flash with the prompt: describe the diagram concisely, focusing on geometric shapes, mathematical concepts, key visual elements, and purpose (~1–3 sentences starting with "A diagram ..."). Only samples with TikZ code shorter than 1000 characters… See the full description on the dataset page: https://huggingface.co/datasets/catslashbin/datikz-v3-recaptioned.cc12m-wds-recaption
