is there a specific reason for MS copilot not being supported as an AI model in DT (even if technically it mostly seems to be a front end to OpenAI’s models)? at least in my neck of the woods copilot seems to have the biggest LLM user base. am I missing something?
Not sure, but I think they don’t have API Keys as others do.
good idea….however I just checked and there seems to be API access for the copilot flavor that comes with microsoft 365 (which would also explain the fairly widespread use)…haven’t tried it yet though…
I have been looking into it, and from Microsoft documentation, the API keys are to integrate AI into an application, and needs the developer that is going to use it, register at Microsoft to get the key, and that key, as others from Microsoft (like the one I used years ago to allow VOIP integration) are secret and hidden into the application, as is the developer who “pays” for the usage. It is completely different of the others format, that is the user who gets the API (and pays for the usage) and puts into DT.

ok, that indeed sounds complex…and a likely explanation why DT does not support copilot…let’s see if somebody else wants to chime in as well, but in any case thanks for following up!
Even if it was supported, you wouldn’t want to use it. Copilot is trash compared to even basic LLMs and doesn’t even work half the time in Microsoft’s own apps.
For general usage Copilot is worth to me, perhaps because I have a paid Office 365 account and itdirecly goes to ChatGPT 5.1, but for Office (read: Word, Excel, …) usage, let me reprhase it: 
. It is an absolute joke, and only when it works, because 9 of 10 it says “error”.
Interesting. I also have a paid account and on the rare occasions I’ve tried to use it just for the hell of it (out of curiosity), I still get that error!
