A Twitch streamer has sued Twitch and Amazon in a proposed class action, claiming the companies used creators’ videos, chats and other content to train generative artificial intelligence models without their consent or compensation.
Warren Pandiscia, a Connecticut creator who has streamed on Twitch for nearly a decade, filed the lawsuit Aug. 20 in the U.S. District Court for the Northern District of California. He claims Twitch gave Amazon access to creator content for AI training even though the platform’s agreements with users did not authorize that use.
The lawsuit followed an Aug. 12 announcement from Twitch introducing a setting that allows creators to opt out of having their channel content used to train Amazon’s generative AI models. The setting is enabled by default, requiring creators to turn it off if they do not want their content used for future AI training.
Pandiscia argues the alleged use began before Twitch disclosed the new setting. His complaint claims the companies had already used creator material for AI work without first obtaining permission and benefited from content produced by streamers at their own expense.
Twitch Chief Product Officer Mike Minton acknowledged in 2024 that Amazon was using Twitch content in some AI work, which he described at the time as prototyping rather than production use. During an Aug. 12 Twitch discussion, Minton said he did not know what Amazon had previously used for model training. Pandiscia claims the alleged use may date back to 2024.
At the center of the lawsuit is what Twitch’s agreement with its users actually allowed. Before the Aug. 12 announcement, the platform’s Terms of Service granted Twitch broad rights to use creator content in connection with its service and monetization. Pandiscia argues that language did not permit Twitch to provide the material for use in Amazon’s separate generative AI business.
Twitch also changed its Terms of Service on Aug. 12. The revised language expanded provisions governing how creator content could be used to include business activities involving Twitch affiliates. Amazon is Twitch’s parent company. The platform also updated its privacy disclosures to expressly address machine learning, artificial intelligence and generative AI.
Pandiscia argues those revisions support his claim that the earlier agreement did not already authorize the broader use.
Platform terms can give a company broad rights to use material posted by its users, but those rights remain governed by the language of the agreement. The dispute centers on whether Twitch’s earlier license covered uses connected to the platform itself or also allowed creator material to be used elsewhere within Amazon’s business.
The complaint also invokes the duty of good faith and fair dealing, a contract principle that generally prevents one party from using its rights under an agreement in a way that unfairly deprives the other side of the benefits of the deal. Pandiscia argues Twitch violated that duty through its handling of creator content and the way the alleged AI use was disclosed.
Pandiscia also accuses Twitch and Amazon of violating California’s Unfair Competition Law. The law allows challenges to business practices alleged to be unlawful, unfair or fraudulent. He claims the companies’ use of creator material and their disclosures about AI training fall within those categories.
The lawsuit further seeks recovery under an unjust enrichment theory, with Pandiscia arguing that Amazon received commercially valuable training material without paying the creators who produced it.
Unlike many lawsuits challenging the use of creative work to train AI systems, Pandiscia does not accuse Twitch or Amazon of copyright infringement. His claims instead focus on Twitch’s agreements with creators, the companies’ alleged benefit from their content, and California business law.
Pandiscia is seeking to represent other Twitch creators whose content was allegedly used without authorization. The lawsuit asks for damages and restitution and seeks court orders restricting future use of creator material for generative AI training without informed consent.
The case remains pending in the U.S. District Court for the Northern District of California.
