+
## Usage
|
| 50 |
+
|
| 51 |
+
```python
|
| 52 |
+
from diffusers import FluxPipeline
|
| 53 |
+
import torch
|
| 54 |
+
|
| 55 |
+
# Load the FP16 model
|
| 56 |
+
pipe = FluxPipeline.from_pretrained(
|
| 57 |
+
"path/to/flux-dev-fp16",
|
| 58 |
+
torch_dtype=torch.float16
|
| 59 |
+
)
|
| 60 |
+
|
| 61 |
+
pipe.to("cuda")
|
| 62 |
+
|
| 63 |
+
# Generate an image
|
| 64 |
+
image = pipe(
|
| 65 |
+
prompt="a beautiful mountain landscape at sunset",
|
| 66 |
+
num_inference_steps=50,
|
| 67 |
+
guidance_scale=7.5
|
| 68 |
+
).images[0]
|
| 69 |
+
|
| 70 |
+
image.save("output.png")
|
| 71 |
+
```
|
| 72 |
+
|
| 73 |
+
## Model Precision Trade-offs
|
| 74 |
+
|
| 75 |
+
**FP16 (This Collection)**:
|
| 76 |
+
- Best quality output
|
| 77 |
+
- Full precision weights
|
| 78 |
+
- Requires more VRAM (16GB+)
|
| 79 |
+
- Slower inference compared to FP8
|
| 80 |
+
- Recommended for: Quality-focused applications, professional use
|
| 81 |
+
|
| 82 |
+
**Alternatives**:
|
| 83 |
+
- FP8: ~50% smaller, faster inference, minimal quality loss
|
| 84 |
+
- GGUF: Quantized variants for memory-constrained scenarios
