There’s a new Sketch style for Image Playground in macOS Sequoia 15.4. Let’s look at how to use it.
But first: a description: Apple describes Image Playground as a “fun” feature that can produce original images in seconds right within apps. Users can create an entirely new image based on a description, suggested concepts, or a person from their Photos library. From there, users can adjust the style and make changes to match a Messages thread, a Freeform board, or a slide in Keynote, for example. To use the Sketch Style:
° Launch the Image Playground app.
° Go to File > New Image.

° Click Animation, then choose between Animation, Illustration, or Sketch styles.

° Enter detailed descriptions to guide the AI process. The more detail you provide, the better your results will be.
