icon-generator-2

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

The main validation prompt used during training was:

minimalist icon

Inference

import torch
from diffusers import DiffusionPipeline

model_id = 'black-forest-labs/FLUX.1-schnell'
adapter_id = 'noahyoungs/icon-generator-2'
pipeline = DiffusionPipeline.from_pretrained(model_id, torch_dtype=torch.bfloat16) # loading directly in bf16
pipeline.load_lora_weights(adapter_id)

prompt = "minimalist icon"


## 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.
