Introduction

We are excited to share our latest model series based on nunchaku + qwen-image-2512 quantization. These models are carefully optimized to maintain high-quality output while significantly improving inference speed and efficiency. All models are 100% compatible with the nunchaku-comfyui && lora plugin and can be used directly in ComfyUI.
