 Note that this model ends up smaller than the Q4_0 from Bartowski. This is because llama.cpp sets some tensors to Q4_1 when quantizing models to Q4_0, but Google decided to use only Q4_0 instead, which is slightly smaller.
 The perplexity scores are barely within margin of error between this model and the original QAT, it seems like the embedding table starts making a difference at this small size, though the trade off is probably still worth it..
