WA Can I run Wan 2.1 T2V 1.3B on AMD Radeon RX 7900 XTX (24GB)?
Yes. Wan 2.1 T2V 1.3B runs on AMD Radeon RX 7900 XTX (24GB) at Q4 GGUF (~6 GB of ~23 GB usable).
Runs at Q4 GGUF using ~6 GB of ~23 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 AMD Radeon RX 7900 XTX (24GB) run Wan 2.1 T2V 1.3B?
Yes. Wan 2.1 T2V 1.3B runs on AMD Radeon RX 7900 XTX (24GB) at Q4 GGUF (~6 GB of ~23 GB usable).
How much VRAM does Wan 2.1 T2V 1.3B need?
AMD Radeon RX 7900 XTX (24GB) 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.
