Reddit

Reddit is a network of user-run forums, called subreddits, where people ask questions and argue about everything from board games to tax law. It matters in AI news for a specific reason: it is one of the largest public archives of ordinary people explaining things to each other in plain language, which turns out to be exactly the material large language models learn best from.

That has made Reddit both a supplier and a litigant. It has signed paid data licensing deals with major AI companies while suing others it accuses of scraping its content without permission, and it has begun adding AI features of its own to the site.
