Quickstart: Generate and verify an image's watermark using Imagen text-to-image (Console)

This quickstart shows you how to use the Imagen on Vertex AI text-to-image feature in the Google Cloud console to perform the following tasks:

• Generate an image: Create an image from a descriptive text prompt.
• Verify a digital watermark: Confirm that the generated image contains a digital watermark.

Before you begin

Concepts

• Imagen on Vertex AI: A feature in Vertex AI that lets you generate or edit images from text prompts.
• Digital watermark: An invisible signal embedded in an image to help identify it as AI-generated.

Learn how to use Imagen on Vertex AI's text-to-image generation feature and verify a digital watermark (SynthID) on a generated image. This quickstart shows you how to use Imagen image generation in the Google Cloud console.

Imagen on Vertex AI pricing is based on the feature you use. For more information, see Pricing.
