How Is LLaMa.cpp Possible?
In case anyone is wondering, yes, there is a cost when a model is quantized.<p><a href="https://oobabooga.github.io/blog/posts/perplexities/" rel="nofollow noreferrer">https://oobabooga.github.io/blog/posts/perplexities/</a><p>Essentially, you lose some accuracy and there might be some weird answers and probably more likely to go off the rail and hallucinate. But the quality loss is lower the more parameters you have. So for very large model sizes the differences might be negligible. Also, this is the cost of inference only. Training is a whole other beast and requires much more power.<p>Still, we are looking at GPT3 level of performance on one server rack. That says something when less than a year ago, such AI was literally magic and only run on a massive datacenter. Bandwidth and memory size are probably, in my ignorance mind, easier to increase than raw compute so maybe we will soon actually have "smart" devices.
