WA Can I run Wan 2.1 T2V 1.3B on Apple M5 Max (128GB)?
Yes. Wan 2.1 T2V 1.3B runs on Apple M5 Max (128GB) at Q4 GGUF (~6 GB of ~96 GB usable).
Runs at Q4 GGUF using ~6 GB of ~96 GB usable.

How to run it
Use ComfyUI or Diffusers at Q4 GGUF. The big text encoder is loaded to encode your prompt, then offloaded before generation, which is why peak VRAM stays near the backbone size rather than the sum of every file.

FAQ
Can Apple M5 Max (128GB) run Wan 2.1 T2V 1.3B?
Yes. Wan 2.1 T2V 1.3B runs on Apple M5 Max (128GB) at Q4 GGUF (~6 GB of ~96 GB usable).
How much VRAM does Wan 2.1 T2V 1.3B need?
Apple M5 Max (128GB) has room to spare. At Q4 GGUF the realistic peak is ~6 GB of VRAM, versus ~20 GB with every component kept resident (no offload). With aggressive CPU offload it drops to ~5 GB, much slower.
What do I use to run Wan 2.1 T2V 1.3B locally?
Wan 2.1 T2V 1.3B runs in ComfyUI or Diffusers. It loads as a video diffusion checkpoint plus its text encoder and VAE, not a single chat command.
