Google's SynthID Watermarks Applied to 180 Billion Media Files, Detector Launched

Google's SynthID watermarks have been applied to 180 billion images and videos. As of October 7, 2026, the SynthID Detector is now publicly accessible, allowing users to verify whether a media file was created by Google's AI or its partners. This tool is expected to handle around 1 million daily verification requests. Google clarified that while SynthID can identify content generated by its AI models, it is not a universal AI detector. Furthermore, Apple is anticipated to join the initiative soon, as indicated by Google. This development follows Google's recent efforts to enhance the adoption of its Gemini AI model and related technologies.
