- **Replicate ID**: `black-forest-labs/flux-schnell`
- **Version**: Latest stable version
## Key Features
- **Ultra-Fast Generation**: One of the fastest models available
- **Consistent Quality**: Maintains high quality despite speed
- **Prompt Adherence**: Excellent understanding of prompt instructions
- **Efficient Processing**: Low computational requirements
## Default Parameters
- **Resolution**: 1024x1024
- **Steps**: 4 (optimized for speed)
- **Guidance Scale**: 3.5
- **Supports Negative Prompts**: Yes
- **Supports Seed**: Yes
## Supported Aspect Ratios
**11 aspect ratios**:
- **Square**: 1:1
- **Landscape**: 4:3, 3:2, 5:4, 16:9, 21:9
- **Portrait**: 3:4, 2:3, 4:5, 9:16, 9:21
## Supported Resolutions
