Model Details

This model is an int4 model with group_size 128 of google/gemma-2b generated by intel/auto-round.

Use the model

INT4 Inference with ITREX on CPU

Install the latest intel-extension-for-transformers

from intel_extension_for_transformers.transformers import AutoModelForCausalLM
from transformers import AutoTokenizer

Evaluate the model

pip3 install lm-eval==0.4.2

pip install auto-gptq

Please note that there is a discrepancy between the baseline result and the official data, which is a known issue within the official model card community.

Here is the sample command to reproduce the model

git clone https://github.com/intel/auto-round
cd auto-round/examples/language-modeling
pip install -r requirements.txt
python3 main.py \
--model_name  google/gemma-2b \
--device 0 \
--group_size 128 \
--bits 4 \
--iters 400 \
--model_dtype "float16" \
--deployment_device 'gpu' \
--output_dir "./tmp_autoround" 

Ethical Considerations and Limitations

The model can produce factually incorrect output, and should not be relied on to produce factually accurate information. Because of the limitations of the pretrained model and the finetuning datasets, it is possible that this model could generate lewd, biased or otherwise offensive outputs.

Therefore, before deploying any applications of the model, developers should perform safety testing.

Caveats and Recommendations

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model.
