Introduction

This guide requires Cerb 10.4.2 or later.

Stable Diffusion¹ is a text-to-image model trained on billions of captioned images. It can be used to generate new images from a given text description.

In this guide we'll use the Stable Diffusion API to generate profile images for workers, groups, roles, etc.

Connect Stability.ai to Cerb

Follow the Stability.ai integration guide to get an API key and connect it to Cerb.

Click the Continue button and select your Stability.ai connected account when prompted.

Generate a profile image

Edit a record (worker, group, role, contact, organization).

For instance:

Click on your name in the top right, then Settings. On the Profile tab, click the Edit button to the right of Photo.
Edit a group from Search » Groups.

Click the new Stable Diffusion button in the Image generation: section.

Type a description of the image you'd like to generate in the prompt:

A profile picture of a techie woman in cyberpunk graphic novel style

Click the blue Continue button.

After a few seconds you'll be given four options from your prompt:

If you like an image, you can select it and press Continue.

Or you can generate a new set of images by clicking Start over.
