Black Forest Labs FLUX — Subject, Action, Style, Context

Pixio: All Flux variants (Dev, Pro, Ultra, Kontext, 2.x, Schnell, etc.) benefit from the same prompt shape, even when speeds and fidelity differ.

The FLUX prompting summary recommends:

Layer	Role
Foundation	Subject + Action + Style + Context
Visual	Lighting, palette, composition
Technical	Camera, lens, quality hints
Atmosphere	Mood and narrative without contradicting light logic

Word order: Put the most important concepts first—FLUX pays more attention to leading tokens.

Length: Often 30–80 words is the sweet spot for general scenes; shorter for exploration, longer when you need layered specs.

Negatives: Prefer positive phrasing (“empty street”) over “no cars”; same idea as BFL’s “working without negatives.”

Text in images: Describe quoted text, placement, and style explicitly when you need legibility.

Example:

“Red fox sitting in tall grass at misty dawn, wildlife documentary photography, soft side light, shallow depth of field, 135mm lens look, no harsh HDR.”
