Generation provenance metadata in FLUX output images

Context

FLUX generates images that are increasingly used in production — marketing, design, content creation. These images carry no metadata indicating they're AI-generated.

EU AI Act Article 50 (August 2, 2026) requires transparency metadata on AI-generated content, including images. Deepfake disclosure becomes mandatory.

Suggestion

Optionally embed generation provenance into output images:

• ai_generated: true
• Model name and version
• Generation timestamp
• Prompt (optional, can be disabled for privacy)

This could live in PNG tEXt chunks or EXIF — zero additional dependencies beyond Pillow.

Reference

• AKF defines provenance fields for AI-generated images
• Already standard in photography (EXIF) — AI images should follow the same pattern
