lejos-borges-simpletuner-lora

This is a LyCORIS adapter derived from stabilityai/stable-diffusion-3.5-large.

The main validation prompt used during training was:

cinematic product photography, a high-detail, realistic studio shot on a pristine white marble surface. A Borges Extra Virgin Olive Oil bottle (1L, green) stands prominently, with a bottle of Borges Natura Apple Cider (500ml, clear glass with golden liquid) positioned slightly behind it. The lighting is bright and diffused, creating soft shadows. The bottles are the sole focus of the image, with no other elements present. The composition is minimalist and sleek, emphasizing the form and packaging of the products.

## 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.
