You can run Z-Image Turbo on your iPhone with Off Grid AI Mobile (OGAM). If you have an iPhone with 12 GB of memory, such as the iPhone 17 Pro or iPhone Air, download Z-Image Turbo (Light) once, about 6 GB, and you get 1024px images with English or Chinese lettering, made on the phone with no internet and nothing uploaded.
It’s free, the model is Apache-2.0, and there’s no subscription or credit pack.

What Z-Image Turbo is
Z-Image Turbo is a 6-billion-parameter image model from Alibaba’s Tongyi Lab, released under Apache-2.0. It makes an image in 8 steps and can write text in pictures in English and Chinese. Tongyi says it fits on a PC graphics card with 16 GB of memory. OGAM runs a smaller quantized build, Z-Image Turbo (Light), that fits a 12 GB iPhone.
OGAM 0.0.122 (4 November 2026) added it to the Image tab, next to the Core ML Stable Diffusion models iPhones already had.
Which iPhones can run it
Apple doesn’t print memory on the box, so here’s the list. These iPhones have 12 GB:
- iPhone 17 Pro and iPhone 17 Pro Max
- iPhone Air
- iPhone 18 Pro and iPhone 18 Pro Max
The iPhone 17, iPhone 16 Pro and iPhone 15 Pro have 8 GB, and Z-Image Turbo (Light) needs 11 GB or more, so OGAM doesn’t show it on those phones.
| Z-Image Turbo (Light) | Z-Image Turbo (2026) | |
|---|---|---|
| Download | About 6.0 GB | About 6.7 GB |
| iPhone memory | 12 GB | Not available on iPhone (needs 16 GB) |
| Quantization | Q3_K | Q4_K |
The download includes the Qwen3 4B Instruct text encoder and the VAE, and the app fetches them together.
Phone support is new. Z-Image Turbo runs on Mac, Windows and Linux today. If it fails on yours, the Core ML models in the same tab are the proven choice, and FLUX.2 klein (Light) needs less memory.
Make your first Z-Image picture
- Install OGAM from the App Store, or update it to 0.0.122 or later.
- Tap Models in the bottom bar, then the Image tab.
- Type Z-Image in Search models.
- Tap Z-Image Turbo (Light) and download it. Use Wi-Fi, because it’s about 6 GB.
- Open a chat and ask for a picture: “draw a bookshop window with a hand-lettered sign reading NEW ARRIVALS, soft afternoon light”. OGAM sees it’s an image request and sends it to your image model.
- To make every message a picture, tap Chat options next to the message box and set Image to ON. Auto lets the app decide.
If you have more than one image model, choose Z-Image in the model picker’s image tab before you send. Keep the words you want drawn short, and put them in quotes or capitals.
The style row above the message box works with Z-Image too. Tap Photoreal or Cinematic before you send, or tap Restyle under a finished picture to draw it again in another look.
Once it’s downloaded, turn on airplane mode and ask for another picture. It still works, because nothing leaves the phone.
If something goes wrong
| What you see | Why | What to do |
|---|---|---|
| Z-Image isn’t in the list | Your iPhone has 8 GB of memory, or the app is older than 0.0.122 | Update OGAM. On an 8 GB iPhone, use a Core ML model such as SD 1.5 Palettized |
| The app stops partway through an image | iOS ran short of memory | Close other apps and try again, or switch to FLUX.2 klein 4B (Light) |
| You want the full Z-Image build | No iPhone has the 16 GB it needs | Make images on your computer from your phone |
FAQ
Can Z-Image Turbo run on an iPhone? Yes, the Light build, on an iPhone with 12 GB of memory: the iPhone 17 Pro, 17 Pro Max, iPhone Air, 18 Pro or 18 Pro Max. Off Grid AI Mobile 0.0.122 added it to the Image tab, and it shows only on iPhones with enough memory to load it.
Can I run the full Z-Image Turbo on an iPhone? No. The full build needs a device with 16 GB of memory, and no iPhone has that. The Light build is the same model at a smaller size, and it’s the one Off Grid AI offers on 12 GB iPhones.
Does Z-Image Turbo work on an iPhone 16 Pro or iPhone 17? No. Those have 8 GB of memory, and Z-Image Turbo (Light) needs 11 GB or more. Off Grid AI hides it there. Use a Core ML Stable Diffusion model instead.
Is Z-Image Turbo free on iPhone? Yes. Image generation is part of the free Off Grid AI app, and Z-Image Turbo is released under Apache-2.0. There’s no account, no subscription and no limit on images.
Does Z-Image Turbo work offline on iPhone? Yes, after the download. The model runs on your iPhone, so you can turn on airplane mode and keep making images. Your prompts and pictures are never uploaded.
