Z-Image-Engineer V6 GGUF

GGUF quantized release for Z-Image-Engineer V6.

The main repo contains the merged HF safetensors. This repo contains the quant ladder for LM Studio, ComfyUI CLIPLoaderGGUF, llama.cpp-style loaders, and local prompt-enhancement workflows.

What is this?

Z-Image-Engineer V6 is a SMART DoRA fine-tuned 4B Qwen text encoder from Tongyi-MAI/Z-Image-Turbo.

Use these GGUF files when you want:

• LM Studio prompt enhancement
• ComfyUI Z-Image text-encoder replacement through CLIPLoaderGGUF
• smaller local files than the merged HF safetensors
• the same V6 prompt style and conditioning behavior in a quantized format

Quick Start

LM Studio

Download a GGUF quant, load it, and prompt it directly:

Enhance this image prompt for Z-Image Turbo: a unicorn

The comparison examples were generated from direct LM Studio user requests like this, with no separate system prompt. V6_SYSTEM_PROMPT.md is included only as an optional preset for people who want a stricter prompt-only chat setup.

ComfyUI

1. Place a GGUF file into ComfyUI/models/text_encoders/.
2. Add a CLIPLoaderGGUF node.
3. Set model type to lumina2.
4. Use it where the stock Z-Image Qwen text encoder would normally go.

Verified image settings:

SMART DoRA

V6 was trained with BennyDaBall's SMART DoRA system:

• DoRA for direction/magnitude-separated adapter updates.
• Entropic regularization for less repetition and broader output variety.
• Holographic regularization for cleaner depth-wise feature structure.
• Topological regularization for more coherent latent trajectories.
• Manifold regularization for stable weight behavior during refinement.

The final V6 build used master-corpus SMART DoRA training, retention pressure, SceneClean SFT32 style restoration, AntiRepeat Binary24 refinement, and a 25% style-restoration / 75% anti-repeat DoRA blend.
