## Additional Information
|
77 |
+
- FLUX.1 [schnell] is based on a hybrid architecture of multimodal and parallel diffusion transformer blocks
|
78 |
+
- It supports various aspect ratios within the 0.1 to 2.0 megapixel range
|
79 |
+
- The model uses bfloat16 precision for efficient computation
|
80 |
+
- For optimal performance, running on a CUDA-enabled GPU is recommended
|
81 |
+
