According to Google Gemini on X (@GeminiApp), all Lyria 3 and Lyria 3 Pro outputs now include SynthID, an imperceptible watermark for identifying Google AI–generated content, and users can upload a file to Gemini to check for SynthID and verify provenance. As reported by Google Gemini, this enables rights holders and platforms to authenticate AI music and audio, reducing attribution disputes and easing compliance for UGC platforms and enterprise content pipelines. According to Google Gemini, the workflow is simple: upload a file and ask Gemini if it was generated using Google AI, which supports trust and safety measures and helps brands implement content authenticity checks at scale.

According to @GeminiApp, Google has introduced Nano Banana Pro alongside a major update for Gemini users, enabling them to verify if an image was generated or edited by Google AI through SynthID, their proprietary digital watermarking technology (source: GeminiApp on Twitter, Nov 20, 2025). With this update, users can upload any image to the Gemini app and ask if it is AI-generated. The system scans for SynthID watermarks, which are embedded in all Google AI-generated images, including those created with Nano Banana Pro. This development underscores Google’s commitment to AI transparency and provides businesses with robust tools for digital content verification, addressing growing demands for authenticity in AI-generated media (source: goo.gle/synthid).
