## Model Information

Quantized version of [internlm/internlm3-8b-instruct](https://huggingface.co/internlm/internlm3-8b-instruct) using torch.float32 for quantization tuning.
- 8 bits (INT8)
- group size = 128
- Asymmetrical Quantization
- Method WoQ: SignRound (AutoRound algorithm)

Fast and low memory, 2-3X speedup (slight accuracy drop at W8G128)

Quantization framework: [Intel AutoRound](https://github.com/intel/auto-round) v0.4.7

Note: this INT8 version of internlm3-8b-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. 

```
wget https://github.com/intel/auto-round/archive/refs/tags/v0.4.7.tar.gz
tar -xvzf v0.4.7.tar.gz
cd auto-round-0.4.7
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 = "internlm/internlm3-8b-instruct"
  model = AutoModelForCausalLM.from_pretrained(model_name)
  tokenizer = AutoTokenizer.from_pretrained(model_name)
  from auto_round import AutoRound
  bits, group_size, sym, device, amp = 8, 128, False, 'cpu', False
  autoround = AutoRound(model, tokenizer, nsamples=128, iters=200, seqlen=512, batch_size=4, bits=bits, group_size=group_size, sym=sym, device=device, amp=amp)
  autoround.quantize()
  output_dir = "./AutoRound/internlm_internlm3-8b-instruct-autoround-int8-gs128-asym"
  autoround.save_quantized(output_dir, format='auto_round', inplace=True)
```
