A 4-bit (NF4) quantized build of Z-Image (Apache-2.0), packaged by VIDRAFT for low-VRAM, on-device image generation — part of the POCKET line.

📦 ~6 GB on disk (transformer + text encoder in NF4, VAE in fp16)
⚡ Runs from ~8.6 GB VRAM (≈4.5 GB with CPU offload) — vs 23.3 GB for bf16
🎯 ~2.7–5× smaller footprint, quality on par with the bf16 base

Usage

python

import torch
from diffusers import ZImagePipeline   # or ZImageImg2ImgPipeline / ZImageInpaintPipeline

pipe = ZImagePipeline.from_pretrained(
    "FINAL-Bench/POCKET-Image-Zimage", torch_dtype=torch.bfloat16
).to("cuda")
img = pipe("a serene mountain lake at sunrise, photorealistic", num_inference_steps=20).images[0]
img.save("out.png")

Requires bitsandbytes (CUDA). Measured reload + generate peak: ~10.9 GB VRAM. For Apple Silicon / CPU, an optimum-quanto int8 build (~13.4 GB) is the portable option.
