The Large-scale Artificial Intelligence Open Network (LAION) is a German non-profit with a stated goal “to make large-scale machine learning models, datasets and related code available to the general public”. It is best known for releasing a number of large datasets of images and captions scraped from the web which have been used to train a number of high-profile text-to-image models, including Stable Diffusion and Imagen.
LAION seems to be the antidot for OpenAIs ChatGPT. 100% non-profit. 100% free.
