## Model Information
Quantized version of [ibm-granite/granite-3.3-2b-instruct](https://huggingface.co/fbaldassarri/ibm-granite/granite-3.3-2b-instruct) using torch.float32 for quantization tuning.
- 8 bits (INT8)
- group size = 128
- Symmetrical Quantization
- Method WoQ (AutoRound format)
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 granite-3.3-2b-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 = "ibm-granite/granite-3.3-2b-instruct"
model = AutoModelForCausalLM.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)
from auto_round import AutoRound
bits, group_size, sym, device = 8, 128, True, '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/ibm-granite_granite-3.3-2b-instruct-autoround-int8-gs128-sym"
autoround.save_quantized(output_dir, format='auto_round', inplace=True)
```
