I dont want to hide, Im building the same things as you but only for internal use for now, coz network infra are critical to an enterprise.

I do try to test with GPT/opus to let them answer CLI related questions.
Just my experience, the answer has higher rate of wrong than they answer coding question even I've provided the device type and OS verison.
