| # Flux-dev-de-distill |
|
|
| This is an experiment to de-distill guidance from flux.1-dev. We removed the original distilled guidance and make true classifier-free guidance reworks. |
|
|
| ## Model Details |
|
|
| Following Algorithm 1 in [On Distillation of Guided Diffusion Models](https://arxiv.org/abs/2210.03142), we attempted to reverse the distillation process by re-matching guidance scale w. we introduce a student model |
| x(zt) to match the output of the teacher at any time-step t ∈ [0, 1] and any guidance scale w ∈ [1, 4]. We initialize the student model with parameters from the teacher model except for the parameters related to w-embedding. |
|
|
| Since this model uses true CFG instead of distilled CFG, it is not compatible with diffusers pipeline. Please use [inference script](./inference.py) or manually add guidance in the iteration loop. |
|
|
| Train: 150K Unsplash images, 1024px square, 6k steps with global batch size 32, frozen teacher model, approx 12 hours due to limited compute. |
|
|
| Examples: Distilled CFG / True CFG |
