Runtime profile
Source description
This workflow uses a light iterative latent upscale pass to significantly increase LoRA influence and overall detail quality on Z-Image-Turbo. Uses Impact pack and RGThree.
Generate base image normally (8–12 steps)
Connect to Iterative Latent Upscale (Impact Pack):
Upscale factor: 1.1–2
Steps: 1 to 3. Depends what effect you want. I run with 1 most of the time
Denoise: 0.22–0.49
Use same model, LoRA(s) and strength as base generation
Main effects
AI-generated commentary
AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.
Use this ZImageTurbo workflow to apply an iterative latent upscale to a normally generated base image, reusing the same model, LoRA(s), and strength to produce an upscaled image.
Generate the base image normally in 8–12 steps, then connect it to Iterative Latent Upscale (Impact Pack).
The described results are stronger LoRA style or character expression, sharper details and textures, and better facial features and micro-details without major composition changes.
The workflow declares these node packs: comfyui_essentials, comfyui-impact-pack, and rgthree-comfy.
Named model files include ae.safetensors (VAE), qwen_3_4b.safetensors (text encoder), Soyjak 2 z.safetensors (LoRA), and z_image_turbo_bf16.safetensors (UNet).
Try an upscale factor of 1.1–2 and denoise of 0.22–0.49; choose 1–3 steps for the effect you want. The author says they usually use 1 step.
Suggestion
The workflow names Soyjak 2 z.safetensors as a LoRA; confirm that this is the file you want to use.
