Model Card

hwasan-toml-sd35medium-1024-lora-1000

This is a standard PEFT LoRA derived from stabilityai/stable-diffusion-3.5-medium.

The main validation prompt used during training was:

[trigger]
keyword = "k4s4"

[scene]
panel = 1
camera = "medium-shot"
description = "The scene depicts two characters in a heated exchange, with one character appearing visibly distressed or angry. They are engaged in a conversation, as indicated by the speech bubbles. The background is not clearly defined, suggesting an interior space, possibly a room with limited visibility of details. The shot captures both characters from a medium distance, emphasizing their expressions and the intensity of the moment."

[speech_bubbles]
count = 2

[people]
count = 2
description = "Two characters engaged in a heated exchange, one appearing visibly distressed or angry."

## 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.
