Updated: 2026-06-15

**Yes, but tight.** Fits at fp8 + offload (~10 GB of ~10.5 GB usable) but with little headroom; close other apps.

- Model: 2B DIT video model, peak ~10 GB VRAM at fp8 + offload
- Device: 16 GB unified, ~10.5 GB usable
- All components resident (no offload): ~12 GB
- Offload floor (slow): ~6 GB
- Tools: ComfyUI, Diffusers
- License: LTX-Video Open Weights (OpenRAIL-M) (commercial use: yes)
