Reddit filed a lawsuit against AI startup Anthropic, accusing the Claude chatbot developer of unlawfully training its models on Reddit users’ personal data without a license.

Reddit sued the artificial intelligence startup Anthropic on Wednesday, accusing it of stealing data from the social media discussion website to train its AI models despite publicly assuring it wouldn't.

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.
