Why this exists

Every image model assumes you have a GPU. Most machines don't.

POCKET-Zimage-CPU is Z-Image-Turbo packaged so that a plain office PC — no graphics card, no CUDA, no Python environment — produces a photoreal 512×512 image in under a minute. One binary, three files, done.

Samples

<table> <tr> <td width="33%"><img src="./samples/apple3steps.png" width="100%"><br>_{<b>3 steps</b> · 48.6 s · the default we ship}</td> <td width="33%"><img src="./samples/apple4steps.png" width="100%"><br>_{4 steps · 60.7 s · no visible gain}</td> <td width="33%"><img src="./samples/applekoreanprompt.png" width="100%"><br>_{Korean prompt · note it lost the count}</td> </tr> </table>

_{Prompt: <code>a red apple on a wooden table, photorealistic</code> — Korean: <code>나무 탁자 위에 놓인 빨간 사과, 사실적인 사진</code>. Same seed, CPU only.}

Measured, not claimed

All numbers below are from our own runs. GPU count used: zero.

_{Intel Xeon Gold 6526Y ×2 (32 cores / 64 threads), 48 threads, Q4_0, 3 steps, --fa --vae-tiling. Single run per row.}

Korean prompts cost nothing extra — 45.3 s vs 46.4 s. Language is not a speed penalty here.

How it got 5.3× faster

We started at 244 seconds and ended at 46. Every step is measured:

The big one is step count. Z-Image Turbo is distilled for few-step sampling, but the tool's default is 20. Using the default throws away 5× for nothing.

3 steps is the floor. At 4 and 3 we cannot tell the images apart. At 2 the surface collapses — water droplets and wood grain vanish and the texture turns cloth-like.

`--vae-tiling` is free. It cuts VAE time 16% and peak RAM by 1.27 GB. At 1024×1024 it is the difference between 13.3 GB and 6.76 GB.

Do not use every thread you have. On a 32-core / 64-thread box, 48 threads took 59.5 s and 64 threads took 108.8 s — 1.8× slower. Hyper-threads fight each other for the same physical cores.

Files

The diffusion model here is VIDRAFT's own CPU build of Z-Image-Turbo: 3.51 GB, with no visible quality change.

Run it

Get a stable-diffusion.cpp binary (releases), then:

sd-cli \
  --diffusion-model z_image_turbo-Q4_0-pocket.gguf \
  --vae ae.safetensors \
  --llm Qwen3-4B-Instruct-2507-Q4_K_M.gguf \
  -p "a red apple on a wooden table, photorealistic" \
  --cfg-scale 1.0 --steps 3 --fa --vae-tiling \
  -t 8 -H 512 -W 512 -o out.png

Set -t to your physical core count — not your thread count.

Honest limits

• —It cannot render text. Any words inside the image come out garbled, in every language. If you need accurate text in an image, this is the wrong tool.
• —Korean prompts lose count. "A red apple" gives one apple in English and five or six in Korean. Korean has no articles, so the singular signal is weak for the encoder. Reproduced at both 20 and 3 steps, so it is the encoder, not the step count.
• —1024 × 1024 takes 3 minutes on the machine above. Slower CPUs scale accordingly.
• —Measured on a server CPU. Laptop and mini-PC numbers are not in yet.
