# Can I run LTX-Video 13B on Apple M4 Pro (24GB)?

Updated: 2026-06-15

**No, not enough memory.** Needs ~20 GB at fp8, but only ~16 GB is usable on Apple M4 Pro (24GB). With aggressive CPU offload it can run on as little as ~12 GB, much slower.

- Model: 13B DIT video model, peak ~20 GB VRAM at fp8
- Device: 24 GB unified, ~16 GB usable
- All components resident (no offload): ~38 GB
- Offload floor (slow): ~12 GB
- Tools: ComfyUI, Diffusers
- License: LTX-Video Open Weights (OpenRAIL-M) (commercial use: yes)
