An official quantization of meta-llama/Meta-Llama-3-8B using PV-Tuning on top of AQLM . For this quantization, we used 1 codebook of 16 bits for groups of 16 weights.
The 1x16g16 models require aqlm inference library v1.1.6 or newer:
pip install aqlm[gpu,cpu]>=1.1.6
Note that a large portion of this model are the 16-bit embeddings/logits matrices. You can significantly reduce the model footprint by quantizing these matrices, e.g. using bitsandbytes LLM.int8 or NF4 formats. This does not require additional training.
