That won't really change anything, and in fact make the problem worse. It would be like "getting high on your own supply". Or just making meth at home so you can do it all the time. There's still a "drug dealer" in between you and the code. And you're going to have to pay $$$$ for hardware good enough to not slow you down. I've tried local models on an nVidia 4060 and it's pretty slow.
