How to use the Flux 2 image generator
You do not need to learn a special prompt language. Start with a clear description, use the controls shown in the embedded generator, and refine one detail at a time.
1. Describe the image
Write what should appear in the frame. Include the subject, setting, composition, lighting, and visual style when those details matter. A useful starting prompt might be: “A studio product photo of a red trail-running shoe on dark slate, soft side lighting, three-quarter view, realistic materials.”
2. Choose the available settings
Review the options displayed by the FLUX.2 [dev] interface. Keep your first attempt simple so you can tell whether a later change to the prompt or a setting actually improved the result.
3. Generate, review, and revise
Check the composition, subject details, lighting, and any requested words. If the result misses the mark, change one instruction at a time—for example, the camera angle or background—instead of rewriting the entire prompt.
