Starting April 29, 2025, Gemini 1.5 Pro and Gemini 1.5 Flash models are not available in projects that have no prior usage of these models, including new projects. For details, see Model versions and lifecycle.
By default, Imagen on Vertex AI adds a digital watermark to any image generated by a model version that supports watermarking. This non-visible digital watermark, called SynthID, helps you identify AI-generated images.
This page shows you how to use the Google Cloud console to verify if an image contains a SynthID watermark.
Verify an image watermark
To verify an image watermark:
In the Google Cloud console, go to the Vertex AI > Media Studio
page.
