AI Image Generation Action in Workflows

Generate Images in Workflows

You can now generate an image inside a workflow. The AI Image Generation action is available under AI Actions. Give it a prompt. An AI model creates the image, stores it at a public URL, and returns that URL as text.

This is a premium action. Each execution has an additional charge.

Model Selection

  • Four models: Select GPT Image 2, Gemini 3 Pro Image (Nano Banana Pro), Gemini 3.1 Flash Image (Nano Banana 2), or Gemini 2.5 Flash Image (Nano Banana).
  • Flexible prompts: Type the prompt yourself or insert a custom value. The prompt can come from a contact field, a webhook payload, or an earlier action.
  • Enhance Prompt: One click expands a short prompt into a detailed one.
  • Templates: Start from Product Mockups, Social Post, Promo Flyer, or Lifestyle.
  • Quality: Set Auto, High, Medium, or Low. The default is Auto.
  • Brand control: Apply your Design Kit and Brand Voice.
  • Output control: Set the size, the background, and the file format.
  • Automatic storage: Each image goes to Media Storage and returns an Image URL variable for the actions that follow.

Cost Estimates

Image generation is billed per execution. The figures below show what a typical image costs. Most generations land in this range.

Note: Treat these figures as a planning estimate, not a fixed rate.

Your actual cost per image depends on how you configure the action. The main factors are:

  • Model: The model you select.
  • Quality: The level you set.
  • Size: The size you generate at.
  • Additional context: A Design Kit or Brand Voice passes extra context to the model, which can shift the cost.

Using AI Image Generation

  1. Go to Automation > Workflows.
  2. Open a workflow, then add the AI Image Generation action.
  3. Select the model and set the quality. The default is Auto.
  4. Write the prompt. Type it in, or insert a custom value so the prompt comes from your data at run time.
  5. Click Enhance Prompt or start from a template. Both steps are optional.
  6. Open Additional Settings for the size, the background, the output format, the Design Kit, and the Brand Voice. This step is optional.
  7. Save the action.

Important Information

The generated image is stored at a public URL. Anyone with the link can open it without a login. Keep this in mind when a prompt pulls in customer data.

A workflow can now create a visual, not only move one you uploaded in advance. Use the Image URL in the actions that come after. You can attach it to an email or SMS, publish it to a social post, save it to a custom field, or pass it to a webhook. Because the prompt can come from your data, one workflow can produce a different image for every contact, or fill in an image URL for every row in a Google Sheet.

One change beyond the paste: your pricing copy revealed the quality levels, so I pulled Quality into its own bullet under What’s New and named them. That mirrors the Detail level bullet in the Analyze Image doc.
