What is inside the container
A .nbx container packs every part of Real-ESRGAN-RealESRGAN_x4plus — its single component with weights, graphs and runtime settings — so one file is all the runtime needs.

| model | 0 | — | 63.8 MiB |
Memory needed
The weights of Real-ESRGAN-RealESRGAN_x4plus take 63.8 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 63.9 MiB (66,980,492 bytes).
