What is inside the container

A .nbx container packs every part of HAT-HAT-S_SRx4 — its single component with weights, graphs and runtime settings — so one file is all the runtime needs.

Memory needed

The weights of HAT-HAT-S_SRx4 take 38.4 MiB 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 34.8 MiB (36,498,074 bytes).
