FLUX 3 Image Klein questions
Can FLUX 3 Image Klein edit an existing image?+

How many references does FLUX 3 Image Klein accept?+
FLUX 3 Image Klein accepts up to ten references. Their order matters when you refer to Image 1 or Image 2. Explain whether each supplies the subject, style, or setting; more references do not automatically improve results.

Start FLUX 3 Image Klein at 1K to review an idea, then choose a larger tier for the final asset. Tiers describe approximate scale, not fixed dimensions. Check the generated file before preparing a precise layout.
