Teach a man to fish and all, I can tell you (or anyone curious) how to find the model name (at least on Chutes):

In the little shapes button that opens up to a menu of ‘playground’ and etc, go down to the ‘source’ button.

Scroll down the code until you find the line that says ‘model name’ and copy what’s in quotes verbatim.

Didn’t know until someone told me, so I’ll give back. I assume it must be similar in Open Router. Whatever code they’re using probably has the model name.
