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.

The online discussion forum says Anthropic continued to access its site more than 100,000 times after saying it had stopped.

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.
