Twitch has added an account setting that lets users opt out of having channel content used to train Amazon’s generative AI models, according to reports from The Verge and Engadget. The setting is labeled “Training for Generative AI,” and The Verge reports that it appears under Twitch’s Security and Privacy tab. The opt-out applies to future training of Amazon models whose purpose is to generate or synthesize text, audio, images, or video, both outlets report, citing Twitch support-page language. Twitch says the covered content includes streams, video-on-demand versions, clips, stream chats, and pictures and text on a user’s channel. The scope matters: this is not a broad opt-out from all AI or machine-learning features on Twitch. The Verge reports that captions and safety tools will still function after a user disables the training toggle. Engadget similarly reports that content may still be used for other AI- or machine-learning-powered purposes, including automated captions, and says Twitch describes some safety functions as community-wide systems rather than per-user settings. Twitch’s own setting language, quoted by The Verge, says turning the toggle off does not opt users out of Twitch and Amazon using channel content for other purposes described in the Twitch Privacy Notice. The examples cited in the report include AI-supported features tied to streamer growth and monetization, viewer discovery, and community safety. There is also a boundary around chat participation. If a user posts in another streamer’s chat, both outlets report that the streamer’s opt-out preference governs whether that chat content can be used for generative AI training. In practice, a user’s own setting controls their channel, not every place their messages may appear on Twitch. One detail remains less clear from the provided reports: the default state of the toggle. The Verge says the toggle was on when it checked and that it asked Amazon whether that is the default. Engadget says some users may not have realized the setting was automatically enabled. Until Twitch or Amazon clarifies the default behavior, the safest read is that users who care about the setting should check it directly. For creators, the change gives a more explicit control over whether their channel content feeds Amazon’s future generative AI training. For Twitch and Amazon, it preserves room to keep other AI-supported platform functions operating even when a creator opts out of generative model training. Who benefits: Twitch creators and users who do not want their channel content used for future Amazon generative AI training gain a direct control. Twitch and Amazon also preserve their ability to run other AI-supported platform features outside that specific opt-out. Who's exposed: Users who leave the toggle enabled may have covered channel content used for future Amazon generative AI training. Chat participants are also exposed to another user’s preference when they post in someone else’s stream chat.
