# Load base model
pipe = DiffusionPipeline.from_pretrained(
    "Qwen/Qwen-Image",
    torch_dtype=torch.bfloat16
)

# Load LoRA weights
pipe.load_lora_weights("Limbicnation/saurian-oracle-qwen-lora")

# Move to GPU
pipe = pipe.to("cuda")

# Generate image
prompt = "saurian_oracle, remarkable being with ancient and advanced metallic armor in a high-tech futuristic setting, captivating atmosphere, highly detailed, professional photography, masterpiece, best quality"
image = pipe(
    prompt,
    num_inference_steps=20,
    guidance_scale=4.0,
    width=768,
    height=768

Limitations and Bias

• The model is trained on a small dataset (23 images) and may have limited variation
• Best results are achieved when using the trigger word "saurian_oracle"
• The model is optimized for the specific character design concept and may not generalize well to other concepts
• Generated images may inherit biases present in the base Qwen-Image model

Technical Specifications

• Model Size: ~282 MB per checkpoint
• Format: SafeTensors
• LoRA Modules: 840 U-Net modules
• Text Encoder: Not trained (base model text encoder used)
