Twitch uses machine learning models trained on billions of daily data events to detect fraud, personalize gift subscription recipients, and optimize Hype Train engagement settings for each channel.

The State of Engineering 2023 blog states: "Twitch generates billions of data events every day and our teams have specialized in building data pipelines and machine learning models to leverage that information. These teams empower a more intelligent, personalized and secure environment. Their work enables Twitch to select more interested gift subscription recipients, configure the most engaging Hype Train settings and identify instances of fraud." Twitch's data platform ("Tahoe") contains over 100 petabytes of data and ingests approximately 3 million events per second via the Spade event system. The Community Insights team processes over 10 million events per minute for streamer analytics.
