How to use FLUX Pro 1.1

1
Write a detailed prompt
Describe subject, lighting, and lens. FLUX Pro responds well to photography vocabulary — '85mm f/1.4, golden hour, shallow depth of field'.
2
Pick aspect ratio and resolution
1024×1024 is fastest. 1440×1440 costs ~50% more credits but gives larger prints.
3
Generate
Oakgen runs FLUX Pro via FAL with WaveSpeed as automatic fallback. Generation typically completes in 6–10 seconds.

Compared to other models

vs. midjourney — prompt adherence

FLUX Pro 1.1 follows prompts more literally than Midjourney v6. For specific compositions — 'man in red shirt holding a blue umbrella in rain' — FLUX nails it first try; Midjourney often re-interprets.

vs. imagen-4-ultra — skin texture

Imagen 4 Ultra has better in-image text rendering. FLUX Pro 1.1 has better skin texture, hair detail, and micro-expression nuance. Pick FLUX for portraits, Imagen for posters with readable text.
