What is inside the container
A .nbx container packs every part of Wan2.1-T2V-1.3B-Diffusers — 3 components with weights, graphs and runtime settings — so one file is all the runtime needs.
| Component | Blocks | Layers | Weights |
|---|---|---|---|
| transformer | 30 | 30 | 5.3 GiB |
| vae | 11 | — | 484 MiB |
| text_encoder | 24 | 24 | 21.2 GiB |

Memory needed
The weights of Wan2.1-T2V-1.3B-Diffusers take 26.9 GiB in float32. That is the floor for the memory the runtime has to place, spread over the devices it finds; activations come on top and grow with the size and length you ask for. A measured peak per device class is not published for this model yet.
Verify what you downloaded
Every download carries its SHA-256, and the file endpoint sends it in the X-NBX-SHA256 header. The container is 26.9 GiB (28,921,349,565 bytes).
