What is inside the container
A .nbx container packs every part of parakeet-tdt-1.1b — 3 components with weights, graphs and runtime settings — so one file is all the runtime needs.
| Component | Blocks | Layers | Weights |
|---|---|---|---|
| encoder | 0 | — | 4.0 GiB |
| decoder | 0 | — | 27.5 MiB |
| joint | 0 | — | 6.6 MiB |

Memory needed
The weights of parakeet-tdt-1.1b take 4.0 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 4.0 GiB (4,324,139,049 bytes).
