## Model Information

Quantized version of [allenai/Llama-3.1-Tulu-3-8B-SFT](https://huggingface.co/fbaldassarri/allenai/Llama-3.1-Tulu-3-8B-SFT) using torch.float32 for quantization tuning.
- 4 bits (INT4)
- group size = 64
- Asymmetrical Quantization
- Method WoQ (AutoRound format)

Fast and low memory, 2-3X speedup (slight accuracy drop at W4G64)

Quantization framework: [Intel AutoRound](https://github.com/intel/auto-round) v0.4.6

Note: this INT4 version of Llama-3.1-Tulu-3-8B-SFT 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. 

```
wget https://github.com/intel/auto-round/archive/refs/tags/v0.4.6.tar.gz
tar -xvzf v0.4.6.tar.gz
cd auto-round-0.4.6
pip install -r requirements-cpu.txt --upgrade
```

### Step 2 Build Intel AutoRound wheel from sources

```
pip install -vvv --no-build-isolation -e .[cpu]
```

### Step 3 Script for Quantization

```
  from transformers import AutoModelForCausalLM, AutoTokenizer
  model_name = "allenai/Llama-3.1-Tulu-3-8B-SFT"
  model = AutoModelForCausalLM.from_pretrained(model_name)
  tokenizer = AutoTokenizer.from_pretrained(model_name)
  from auto_round import AutoRound
  bits, group_size, sym, device = 4, 64, False, 'cpu'
  autoround = AutoRound(model, tokenizer, nsamples=128, iters=200, seqlen=512, batch_size=4, bits=bits, group_size=group_size, sym=sym, device=device)
  autoround.quantize()
  output_dir = "./AutoRound/allenai_Llama-3.1-Tulu-3-8B-SFT-autoround-int4-gs64-asym"
  autoround.save_quantized(output_dir, format='auto_round', inplace=True)
```
