Can I run Qwen-Image on Apple M3 Pro (18GB)?
Needs ~14 GB at Q4_K_M GGUF, but only ~12 GB is usable on Apple M3 Pro (18GB). With aggressive CPU offload it can run on as little as ~3 GB, much slower.

FAQ
Can Apple M3 Pro (18GB) run Qwen-Image?
Needs ~14 GB at Q4_K_M GGUF, but only ~12 GB is usable on Apple M3 Pro (18GB). With aggressive CPU offload it can run on as little as ~3 GB, much slower.
How much VRAM does Qwen-Image need?
Apple M3 Pro (18GB) does not have enough memory. At Q4_K_M GGUF the realistic peak is ~14 GB of VRAM, versus ~57 GB with every component kept resident (no offload). With aggressive CPU offload it drops to ~3 GB, much slower.
What do I use to run Qwen-Image locally?
Qwen-Image runs in ComfyUI or Nunchaku (SVDQuant 4-bit). It loads as a diffusion checkpoint plus its text encoder and VAE, not a single chat command.
