## Quick Start
Run the following code to quickly load the [Tongyi-MAI/Z-Image-Turbo](https://www.modelscope.cn/models/Tongyi-MAI/Z-Image-Turbo) model and perform inference.
Run the following code to quickly load the [Tongyi-MAI/Z-Image-Turbo](https://www.modelscope.cn/models/Tongyi-MAI/Z-Image-Turbo) model and perform inference. FP8 precision quantization causes noticeable image quality degradation, so it is not recommended to enable any quantization on the Z-Image Turbo model. Only CPU Offload is recommended, minimum 8GB VRAM is required to run.

from diffsynth.pipelines.z_image import ZImagePipeline, ModelConfig

Holds round folding fan with lady, trees, bird. Neon lightning-bolt lamp (⚡️), bright yellow glow, above extended left palm. Soft-lit outdoor night background, silhouetted tiered pagoda (西安大雁塔), blurred colorful distant lights."
