## Model Information

Quantized version of [meta-llama/Llama-3.2-3B-Instruct](meta-llama/Llama-3.2-3B-Instruct) using torch.float32 for quantization tuning.
- 4 bits (INT4)
- group size = 128
- Asymmetrical Quantization

Fast and low memory, 2-3X speedup (slight accuracy drop at W4G128)

Quantization framework: [Intel AutoRound](https://github.com/intel/auto-round)

Note: this INT4 version of Llama-3.2-3B-Instruct has been quantized to run inference through CPU.

## Replication Recipe

### Step 1 Install Requirements

I suggest to install requirements into a dedicated python-virtualenv or a conda enviroment. 

```
python -m pip install <package> --upgrade
```

- accelerate==1.0.1
- auto_gptq==0.7.1
- neural_compressor==3.1
- torch==2.3.0+cpu
- torchaudio==2.5.0+cpu
- torchvision==0.18.0+cpu
- transformers==4.45.2

### Step 2 Build Intel Autoround wheel from sources

```
python -m pip install git+https://github.com/intel/auto-round.git
```

### Step 3 Script for Quantization

```
  from transformers import AutoModelForCausalLM, AutoTokenizer
  model_name = "meta-llama/Llama-3.2-3B-Instruct"
  model = AutoModelForCausalLM.from_pretrained(model_name)
  tokenizer = AutoTokenizer.from_pretrained(model_name)
  from auto_round import AutoRound
  bits, group_size, sym = 4, 128, False
  autoround = AutoRound(model, tokenizer, nsamples=128, iters=200, seqlen=512, batch_size=4, bits=bits, group_size=group_size, sym=sym)
  autoround.quantize()
  output_dir = "./AutoRound/meta-llama_Llama-3.2-3B-Instruct-auto_round-int4-gs128-asym"
  autoround.save_quantized(output_dir, format='auto_round', inplace=True)
```
