This already happens, it is just the base model plus some in context data.
I am personally looking into 'backing up' my individual personal model, but it is not as straight forward as just copy pasting context data ( not if you want sufficiently deterministic/convincing model ). It is a fair amount of things to consider ( and not directly available on mainstream APIs like chatgpt ). Yes, the bare minimum can be done easily, but easy stuff is not as reliable.
