I've spent an embarassing amount of time since the llamas leaked playing with them, the tools to run them, and writing wrappers for them. They are technically alternatives in the sense that they're incomparably better chat bots than anything in the past. But at least for the 30B and under versions (65B is too big for me to run), no matter what fine tuning is done (alpaca, gpt4all, vicuna, etc), the llamas themselves…
Your conclusion seems not to be warranted since you haven't tried out the 65B model.
a like-for-like comparison would be GPT-4 against the larger models like LLaMA 65B, but those cannot be run on consumer-grade hardware
so one ends up comparing the stuff one can run... against the top stuff from OpenAI running on high-end GPU farms, and this technology clearly benefits a lot still from much larger scale than most people can afford
the great revelation this year is how much does it get better as it get much, much bigger without a clear horizon on where will diminishing returns be hit
but at the same time, some useful stuff can be done on consumer hardware - just not the most impressive stuff
