# gpt-j-6b-int4-cw-ov
* Model creator: [EleutherAI](https://huggingface.co/EleutherAI)
 * Original model: [gpt-j-6b](https://huggingface.co/EleutherAI/gpt-j-6b)

## Description
This is [gpt-j-6b](https://huggingface.co/EleutherAI/gpt-j-6b) model converted to the [OpenVINO™ IR](https://docs.openvino.ai/2024/documentation/openvino-ir-format.html) (Intermediate Representation) format with weights compressed to INT4 by [NNCF](https://github.com/openvinotoolkit/nncf).

> [!NOTE]  
> The model is optimized for inference on NPU using these [instructions.](https://docs.openvino.ai/2025/openvino-workflow-generative/inference-with-genai/inference-with-genai-on-npu.html#export-an-llm-model-via-hugging-face-optimum-intel)


## Quantization Parameters

Weight compression was performed using `nncf.compress_weights` with the following parameters:

* mode: **int4_sym**
* ratio: **1.0**

For more information on quantization, check the [OpenVINO model optimization guide](https://docs.openvino.ai/2024/openvino-workflow/model-optimization-guide/weight-compression.html).


## Compatibility

The provided OpenVINO™ IR model is compatible with:

* OpenVINO version 2025.2.0 and higher
* Intel® NPU Driver - Windows* 32.0.100.4023 for Intel® Core™ Ultra processors and higher

## Running Model Inference with [OpenVINO GenAI](https://github.com/openvinotoolkit/openvino.genai)

1. Install packages required for using OpenVINO GenAI.
```
pip install openvino-genai huggingface_hub
```

2. Download model from HuggingFace Hub
   
```
import huggingface_hub as hf_hub

model_id = "OpenVINO/gpt-j-6b-int4-cw-ov"
model_path = "gpt-j-6b-int4-cw-ov"

hf_hub.snapshot_download(model_id, local_dir=model_path)

```

3. Run model inference:

```
import openvino_genai as ov_genai

device = "NPU"
pipe = ov_genai.LLMPipeline(model_path, device)
print(pipe.generate("What is OpenVINO?", max_length=200))
```

More GenAI usage examples can be found in OpenVINO GenAI library [docs](https://github.com/openvinotoolkit/openvino.genai/blob/master/src/README.md) and [samples](https://github.com/openvinotoolkit/openvino.genai?tab=readme-ov-file#openvino-genai-samples)

## Limitations

Check the original model card for [limitations](https://huggingface.co/EleutherAI/gpt-j-6b#limitations-and-biases).
