Streamers sue Twitch and Amazon over AI training with broadcasts

A Twitch streamer has filed a proposed class action in the Northern District of California accusing Twitch and Amazon of copying vast quantities of streamer content—including broadcasts, clips, chat logs and photos—to train Amazon's generative AI without licenses or consent. The suit cites breach of implied contracts and unfair competition. Twitch had announced plans to train AI on platform content with an opt-out that is not retroactive and is tied to individual channels. Amazon acquired Twitch in 2014; the case underscores growing legal scrutiny of AI training on creator content.
