WHY THIS GUIDE EXISTS

Test the workflow,
not the marketing claim.

The workflow keeps prompt intent, requested size, retry count, latency, and the accepted asset together, making it suitable for teams evaluating whether a Flux result is reliable enough for production rather than judging a single attractive image.
