SAFETY REVIEW FOR LAION 5B

There have been reports in the press about the results of a research project at Stanford University, according to which the LAION training set 5B contains potentially illegal content in the form of CSAM. We would like to comment on this as follows:

LAION is a non-profit organization that provides datasets, tools and models for the advancement of machine learning research. We are committed to open public education and the environmentally safe use of resources through the reuse of existing datasets and models.

LAION datasets (more than 5.85 billion entries) are sourced from the freely available Common Crawl web index and offer only links to content on the public web, with no images. We developed and published our own rigorous filters to detect and remove illegal content from LAION datasets before releasing them.

LAION collaborates with universities, researchers and NGOs to improve these filters and are currently working with the Internet Watch Foundation (IWF) to identify and remove content suspected of violating laws. LAION invites the Stanford researchers to join its Community to improve our datasets and to develop efficient filters for detecting harmful content.

LAION has a zero tolerance policy for illegal content and in an abundance of caution, we are temporarily taking down the LAION datasets to ensure they are safe before republishing them.

Following a discussion with the Hamburg State Data Protection Commissioner, we would also like to point out that the CSAM data is data that must be deleted immediately for data protection reasons in accordance with Art. 17 GDPR.
