+## Model Information
+
+Quantized version of [EleutherAI/pythia-2.8b](EleutherAI/pythia-2.8b) using torch.float32 for quantization tuning.
+- 4 bits (INT4)
+- group size = 128
+- Symmetrical Quantization
+- Method AutoGPTQ
+
+Quantization framework: [Intel AutoRound](https://github.com/intel/auto-round)
+
+Note: this INT4 version of pythia-2.8b 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 = "EleutherAI/pythia-2.8b"
+  model = AutoModelForCausalLM.from_pretrained(model_name)
+  tokenizer = AutoTokenizer.from_pretrained(model_name)
+  from auto_round import AutoRound
+  bits, group_size, sym = 4, 128, True
+  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/EleutherAI_pythia-2.8b-autogptq-int4-gs128-sym"
+  autoround.save_quantized(output_dir, format='auto_gptq', inplace=True)
+```
