FLUX Best Practices
Use this skill when generating prompts for any BFL FLUX model to ensure optimal image quality and accurate prompt interpretation.
When to Use
- Creating prompts for FLUX.2 or FLUX.1 models
- Text-to-image (T2I) generation
- Image-to-image (I2I) editing with FLUX.2 models
- Structured scene generation with JSON
- Typography and text rendering
- Multi-reference style transfer
- Color-accurate brand generations
Quick Reference
Prompt Structure Formula
[Subject] + [Action/Pose] + [Style/Medium] + [Context/Setting] + [Lighting] + [Camera/Technical]
Model Selection
| Use Case | Recommended Model | Notes |
|---|---|---|
| Fastest generation | FLUX.2 [klein] | 4B or 9B, sub-second |
| Highest quality | FLUX.2 [max] | Best detail, grounding search |
| Production balanced | FLUX.2 [pro] | Quality + speed |
| Typography/text | FLUX.2 [flex] | Best text rendering |
| Local/development | FLUX.2 [dev] | Open weights |
| Image editing | FLUX.2 [pro/max] | Pass image URL directly to input_image |
| Inpainting | FLUX.1 Fill | Object removal/completion |
| Context editing | FLUX.1 Kontext | Older model, prefer FLUX.2 |
Critical Rules
- NO negative prompts - FLUX does not support negative prompts; describe what you want
- Be specific - Vague prompts produce mediocre results
- Use natural language - Prose/narrative style works best
- Specify lighting - Lighting has the biggest impact on quality
- Quote text - Use "quoted text" for typography rendering
- Hex colors - Use #RRGGBB format with color description
