In its lawsuit, Reddit said Anthropic had also declined to enter into a licensing agreement for data and had unjustly enriched itself at Reddit’s expense.

The social platform alleges that Anthropic used data from Reddit to train its AI. Anthropic denies the claims.

Reddit is suing artificial intelligence startup Anthropic for what it’s calling a breach of contract and for engaging in “unlawful and unfair business acts” by using the social media company’s platform and data without authority.
