A workflow for Z-Image-Turbo focused on high-quality image styles and ease of use.
Style Selector: Choose from eighteen (x2) customizable image styles.
Refiner: Improves final quality by performing a second pass.
Upscaler: Increases the resolution of any generated image by 50%.
Speed Options:
7 Steps Switch: Uses fewer steps while maintaining the quality.
Smaller Image Switch: Generates images at a lower resolution.
Extra Options:
Sampler Switch: Easily test generation with an alternative sampler.
Landscape Switch: Change to horizontal image generation with a single click.
Spicy Impact Booster: Adds a subtle spicy condiment to the prompt.
Preconfigured workflows for each checkpoint format (GGUF / SAFETENSORS).
Includes the "Power Lora Loader" node for loading multiple LoRAs.
The zip contains four workflow files:
amazing-z-image-a_GGUF: Recommended for GPUs with 12GB or less.
amazing-z-image-b_GGUF: similar workflow "a", but with more experimental styles.
amazing-z-image-a_SAFETENSORS: Based directly on the ComfyUI example.
amazing-z-image-b_SAFETENSORS: similar workflow "a", but with more experimental styles.
When using ComfyUI, you may encounter debates about the best checkpoint format. From my experience, GGUF quantized models provide a better balance between size and prompt response quality compared to SafeTensors versions. However, it's worth noting that ComfyUI includes optimizations that work more efficiently with SafeTensors files, which might make them preferable for some users despite their larger size. The optimal choice depends on factors like your ComfyUI version, PyTorch setup, CUDA configuration, GPU model, and available VRAM and RAM. To help you find the best fit for your system, I've included links to various checkpoint versions below.
