LAION-5B Dataset

LAION-5B
Open Source Image-Text Pair Dataset

LAION-5B is currently the largest open-source image-text pair dataset, containing 5.85 billion images and corresponding text descriptions (ALT text), constructed by the LAION organization. The data is extracted from Common Crawl for image-text pairs and filtered for similarity using the CLIP model. It is widely used for training models like Stable Diffusion, DALL-E, and visual language models like CLIP.
