Flux Dev
High-quality 28-step generation for detailed imagery
About Flux Dev
Flux Dev is the quality-focused variant of the Flux family, using a 28-step generation process that produces noticeably sharper detail, more nuanced lighting, and better fine textures than its faster sibling Schnell. Running on fal.ai, it strikes the sweet spot between generation speed and output quality — each image typically arrives in 5–8 seconds. Flux Dev handles complex prompts with multiple subjects particularly well, maintaining spatial coherence and accurate rendering of details like hands, faces, and text. At 5 credits per image it offers a strong balance of quality and value for creators who need production-ready results without the premium price tag.
