# Can I run FLUX.1 dev on iPhone 17?

Updated: 2026-06-15

**No, not enough memory.** Needs ~6.5 GB at Q4 GGUF, but only ~4.5 GB is usable on iPhone 17. With aggressive CPU offload it can run on as little as ~3 GB, much slower.

- Model: 12B DIT image model, peak ~6.5 GB VRAM at Q4 GGUF
- Device: 8 GB unified, ~4.5 GB usable
- All components resident (no offload): ~33 GB
- Offload floor (slow): ~3 GB
- Tools: ComfyUI, Draw Things, diffusers
- License: FLUX.1-dev Non-Commercial License (commercial use: no)
