Reddit’s lawsuit, which was filed Wednesday, accuses the Amazon-backed AI company of breaching its user agreement. “As far back as December 2021…Anthropic was already—without authorization and in direct violation of Reddit’s User Agreement—training Claude on Reddit users” posts, the lawsuit claims.

Reddit has filed a lawsuit against Anthropic, the artificial intelligence company known for developing the Claude chatbot, accusing the firm of improperly harvesting Reddit’s user-generated content to train its AI models.

Reddit is suing Anthropic for training on its site's data without a proper licensing, joining a litany of publishers with similar claims.
