It does for now, but the methods for modifying an LLM are getting increasingly sophisticated. From blending models to doing brain surgery on them to fine tune the weights, there's a lot of new techniques being developed all the time

There's also recently been a breakthrough that cut the ram requirement to 1/6, eventually someone is going to figure out how to train models orderes of magnitude more efficiently

Especially once the AI bubble pops and no one is willing to dump billions into constant iterations
