Four major AI vendors have adopted the SynthID invisible watermark standard for generated content.[^1]

This standard is woven directly into content itself, rather than being placed in file metadata. The matching detector tool identifies watermarked output from all four participating vendors.[^2]

SynthID Detector was originally developed by Google DeepMind. It was first built to recognise output from Google's Gemini, Imagen, Lyria and Veo systems.[^3]

## What this stands on

1. The SynthID watermark is an invisible standard supported by Google, Nvidia, OpenAI, and Kakao, woven into the content itself rather than file metadata. ([lifehacker.com](https://lifehacker.com/tech/i-tested-googles-new-ai-image-detector-and-its-difficult-but-not-impossible?utm_medium=RSS), News)
