  • YouTube rolls out likeness-detection for eligible creators
    October 21, 2025, 10:38 PM EDT. YouTube has officially rolled out its likeness-detection technology to eligible creators in the YouTube Partner Program after a pilot phase. The feature lets creators request removal of AI-generated content that uses their likeness. The first wave was confirmed to eligible creators by email. The system flags videos featuring a creator's face or voice, enabling removal requests, copyright claims, or archiving. Onboarding requires tapping the Likeness tab, consenting to data processing, and identity verification via a QR code, photo ID, and a brief selfie. Creators may opt out, after which scanning stops within 24 hours. The rollout follows a CAA partnership and YouTube's support for the NO FAKES Act to address deceptive AI replicas.
  • YouTube rolls out likeness detection to curb deepfakes
    October 21, 2025, 10:36 PM EDT. YouTube is rolling out a likeness detection tool to curb deepfakes and better protect user identities. The feature is initially limited to members of the YouTube Partner Program and targets cases where an individual's face has been altered with AI. It may not yet catch voice manipulations. To participate, creators must submit a government-issued ID and a brief video selfie to verify identity and provide source material for review. The system works similarly to Content ID, scanning uploaded videos for possible matches and letting reviewers flag infringing content for removal. The rollout underscores growing focus on identity protection as AI-generated media becomes more capable.
  • YouTube rolls out likeness detection to combat AI-generated fakes for creators
    October 21, 2025, 10:34 PM EDT. YouTube is expanding its likeness detection system to help creators defend against AI-generated deepfakes and misinformation. The feature, still in beta, parallels YouTube's existing copyright tools and is rolling out beyond an initial tester group. When available, it will live under the Content detection menu in YouTube Studio. Early demos show it assumes a single host whose likeness is protected, requiring identity verification via a government ID photo and a short video of the face. The move underscores Google's bet on AI content on the platform, even as concerns grow about privacy and data collection. Some creators fear the flood of AI fakes could harm brands and reputations, while bans on AI remain politically contentious.
  • YouTube rolls out AI likeness-detection to flag unauthorized creator content
    October 21, 2025, 10:32 PM EDT. Starting today, creators in YouTube's Partner Program gain access to a new AI likeness-detection feature that helps identify and report unauthorized uploads using their likeness. After verifying identity, creators can review flagged videos in the Content Detection tab in YouTube Studio and submit removal requests for AI-generated content featuring their face. The rollout begins with a first wave and will expand to more creators over the coming months. In early testing, the tool may display videos showing a creator's actual face, not altered versions, and works similarly to Content ID for detecting copyrighted material. Originally announced last year with a CAA pilot, the feature is part of YouTube/Google's broader push to manage AI-generated content-including policies to label AI content and music that mimics voices.
  • China's Zhuque-3 static-fire advances LandSpace toward year-end orbital debut
    October 21, 2025, 10:30 PM EDT. China's startup LandSpace conducted a static-fire test of its reusable Zhuque-3 launcher, advancing toward an orbital debut expected before year-end. The test, staged at the Dongfeng zone, included engine firings from Zhuque-3's nine Tianque-12A methalox engines and a fueling rehearsal while the booster remained anchored. LandSpace says the campaign will proceed with a vertical integration rehearsal, followed by inspection and maintenance ahead of an orbital launch and first-stage recovery. Standing about 66 meters tall, Zhuque-3 aims to haul roughly 18 metric tons to LEO, a capacity near that of the Falcon 9 but with methane/LOX propulsion differences. The effort builds on LandSpace's Zhuque-2 program and comes as the company presses toward a potential year-end debut amid a string of prior milestones and a recent liftoff anomaly.
