How it is used
Sellers differ between marketing names and internal model codes, such as "Galaxy S23 Ultra" versus "SM-S918B", so publish which form you send. On Chrome for Android the reduced user agent string no longer carries the model; device.sua.model, from client hints, does.
Example
Where the field sits in a payload, with everything else left out:
{
"id": "req-1",
"device": {
"model": "Pixel 8"
}
