This is a standard PEFT LoRA derived from black-forest-labs/FLUX.1-dev.

The main validation prompt used during training was:

A peaceful Japanese-inspired scene unfolds, showcasing a cozy retreat nestled in the heart of nature. Towering mountains rise in the distance, framing a serene environment filled with vibrant plants and lush greenery. A calm pond reflects the bright sunlight, its surface adorned with delicate ripples and blooming lotus flowers. Nearby, a rose garden adds a touch of romance, its soft petals contrasting beautifully with the earthy tones of the surroundings. The setting exudes tranquility, inviting you to pause, breathe, and connect with the harmony of nature. It's a perfect haven where the natural beauty of Japan's landscapes meets cozy serenity.

## Optional: quantise the model to save on vram.
## Note: The model was quantised during training, and so it is recommended to do the same 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
image = pipeline(
    prompt=prompt,
    num_inference_steps=20,

Exponential Moving Average (EMA)

SimpleTuner generates a safetensors variant of the EMA weights and a pt file.

The safetensors file is intended to be used for inference, and the pt file is for continuing finetuning.

The EMA model may provide a more well-rounded result, but typically will feel undertrained compared to the full model as it is a running decayed average of the model weights.
