Source description
This release introduces the second generation of "Z-Sampler Turbo", with the internal code completely rewritten from scratch. It follows the same core principle as the first generation (3 stages with their respective sigma sets) but adds new functionality and, more importantly, better parameterization of the internal sampling process.
Thanks to this rewrite, I've been able to implement the following controls:
AI-generated commentary
AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.
Generate Z-Image Turbo images with the second-generation Z-Sampler Turbo; adjust Intensity, Intensity Bias, and Turbo Creativity to shape the final image.
Sampling follows three stages, each with its own sigma set.
The sampler controls affect detail intensity and its washed-out look, brightness and detail at extreme intensity values, and compositional variety; Turbo Creativity aims to preserve style and color tone.
Install the included nodes through ComfyUI-Manager or manually from the ComfyUI-ZImagePowerNodes GitHub repository.
Across the examples, listed model files include ae.safetensors, qwen_3_4b.safetensors, Qwen3-4B-Q8_0.gguf, and z_image_turbo-Q5_K_S.gguf.
GGUF examples also name comfyui-gguf.
Use Intensity to adjust how strong or washed out details appear, Intensity Bias to adjust brightness and detail at extreme intensity values, and Turbo Creativity to seek more compositional variety without changing style or color tone.
Check the model files for the specific BF16, FP8, or GGUF example you choose; the listed files vary between examples.

Intensity : adjusts how intense or "washed out" the details in the final image appear.
Intensity Bias : allows you to adjust the "brightness" and details produced by extreme intensity values.
Turbo Creativity : aims to bring more compositional variety to the image without altering its style or color tone.
