About FLUX Dev

FLUX Dev is the 12-billion-parameter middle child of the FLUX line — more detail and tighter prompt-following than the free Schnell, without the price of 1.1 Pro. At 1 credit it’s the sensible step up.

Unlike Schnell’s four steps, Dev runs the full denoise (28 steps here), so it holds finer detail and handles busy, multi-part prompts more gracefully.

Reach for it when the free output isn’t quite cutting it but the job doesn’t need top-end Pro polish.

Best for

  • Detailed images at a low price point
  • Complex prompts with multiple elements
  • A step up from free FLUX Schnell
  • General creative and concept work

Not ideal for

  • Maximum commercial-grade fidelity (use FLUX 1.1 Pro)
  • Readable text (use Ideogram V3)
  • Free generation (use FLUX Schnell)

Example prompts

  • A steampunk airship docked above a Victorian city, intricate detail, golden hour
  • A bioluminescent jellyfish floating in deep ocean, dark background, glowing
  • A medieval blacksmith’s workshop, warm firelight, highly detailed interior

How it runs on ArtifyAI

Dev runs with go_fast on, guidance 3.5, 1-megapixel output, 28 steps and prompt strength 0.8 — a balance of detail and speed. Set your aspect ratio and format and go.
