brunopio/Llama-3.2-1B-Instruct-nbits4-GS64-Axis1-HQQ

This is a version of the Llama-3.2-1B-Instruct model quantized to 4-bit via Half-Quadratic Quantization (HQQ): https://mobiusml.github.io/hqq_blog/

To run the model, install the HQQ library from https://github.com/mobiusml/hqq and use it as follows:

model_id = 'brunopio/Llama-3.2-1B-Instruct-nbits4-GS64-Axis1-HQQ'

from hqq.engine.hf import HQQModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained(model_id)
model     = HQQModelForCausalLM.from_quantized(model_id)

Limitations:
-Only supports single GPU runtime.
-Not compatible with HuggingFace's PEFT.
