Auraflow-DomoKun-LoRA-rank8

This is a PEFT LoRA derived from terminusresearch/auraflow-v0.3.

The main validation prompt used during training was:

An domokun running through a field with flowers all around him.

Validation settings

  • —CFG: 4.0
  • —CFG Rescale: 0.0
  • —Steps: 30
  • —Sampler: FlowMatchEulerDiscreteScheduler
  • —Seed: 42
  • —Resolution: 1024x1024

Note: The validation settings are not necessarily the same as the training settings.

You can find some example images in the following gallery:

The text encoder was not trained. You may reuse the base model text encoder for inference.

Inference

python
import torch
from diffusers import DiffusionPipeline

model_id = 'terminusresearch/auraflow-v0.3'
adapter_id = 'bghira/Auraflow-DomoKun-LoRA-rank8'
pipeline = DiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.bfloat16) # loading directly in bf16
pipeline.load_lora_weights(adapter_id)

prompt = "An domokun running through a field with flowers all around him."
negative_prompt = 'ugly, cropped, blurry, low-quality, mediocre average'

## Optional: quantise the model to save on vram.
## Note: The model was not quantised during training, so it is not necessary to quantise it during inference time.
#from optimum.quanto import quantize, freeze, qint8
#quantize(pipeline.transformer, weights=qint8)
#freeze(pipeline.transformer)
    
pipeline.to('cuda' if torch.cuda.is_available() else 'mps' if torch.backends.mps.is_available() else 'cpu') # the pipeline is already in its target precision level
model_output = pipeline(
    prompt=prompt,
    negative_prompt=negative_prompt,
