# Can I run Wan 2.1 T2V 1.3B on Apple M1 (8GB)?

Updated: 2026-06-15

**No, not enough memory.** Needs ~6 GB at Q4 GGUF, but only ~5.5 GB is usable on Apple M1 (8GB). With aggressive CPU offload it can run on as little as ~5 GB, much slower.

- Model: 1.3B DIT video model, peak ~6 GB VRAM at Q4 GGUF
- Device: 8 GB unified, ~5.5 GB usable
- All components resident (no offload): ~20 GB
- Offload floor (slow): ~5 GB
- Tools: ComfyUI, Diffusers
- License: Apache-2.0 (commercial use: yes)
