+`black-forest-labs--FLUX.1-schnell--transformer-single-layer-bf16` is a single layer with random weights.
+It is meant to help for faster iteration when working with the model.
+
+The actual model `black-forest-labs--FLUX.1-schnell--black-forest-labs-transformer-bf1` is with real pretrained parameters and has 19 MMDiT layers.

 ### T5 Encoder (part of Flux.1 dev)
 
 Only the `xxl` variant is actually used in FLUX. The `small` variant is provided for faster iteration if needed.
