Talking about Create high-quality images using Image Playground, what styles can be used / available, how it works with concepts from my app?

In Create high quality images using Image Playground, the available styles are:

• illustration
• sketch
• animation
• emoji

The session also mentions:

• external provider as an opt-in style, which shows up if the user has configured a third-party provider in Settings
• support for “any style” via natural-language prompting, including styles like oil painting or vector
• the keynote also noted photorealistic image generation

How it works with concepts from your app

You can seed Image Playground with concepts from your app so the generated image starts with relevant context instead of a blank slate.

Examples from the session:

• A card can carry a style preset that maps to the style options
• You can pass size, style, and personalization through ImagePlaygroundOptions and ImagePlaygroundStyle
• Concepts act as visual inspiration, not a constraint — the user can still replace or refine them in the sheet
• A drawing from your app can be passed as a concept, and the model treats it as a visual suggestion guiding composition
• The sheet can also be seeded with context from your app for a richer initial experience

So in practice, your app provides the story/context/concepts, and Image Playground handles the generation and lets the user refine the result.
