About AI artwork

Last updated September 26, 2026

FoilPass can paint poster artwork for your pass. Here is exactly how that works.

The model

Images are made on Cloudflare Workers AI with FLUX.2 [klein] 4B by Black Forest Labs, an openly licensed (Apache 2.0) image model. They're generated when you tap Generate and aren't used to train anything.

What you can ask for

Everyone can pick from preset styles such as holographic foil, risograph, watercolor or chrome. Pro members can also describe their own artwork. Every image is made without text, logos or people.

What we check

• Descriptions are screened for brands, logos, real people and adult content, then checked by an automated safety model (Llama Guard) before any image is made.
• Each image has a Report button. Reported images are reviewed.
• We keep only a hash of your description, never the text itself, for 90 days.

How it's labelled

The app marks generated images as AI-generated, and the back of a pass with AI artwork says "The artwork on this pass was generated with AI."
