Twitch, a popular live streaming platform, has informed its users that their content may have been used to train Amazon's artificial intelligence models. The company now offers users the option to opt out of contributing to the development of these AI models. This change comes as a result of Twitch's efforts to be more transparent about how user-generated content is used. While the platform has been using user content to train its AI for years, users can now choose to prevent their content from being used for this purpose. This development is significant because it highlights the importance of user consent in the use of their data for AI training.
