# codegen2-3_7B_P-int8-ov

 * Model creator: [Salesforce](https://huggingface.co/Salesforce)
 * Original model: [codegen2-3_7B_P](https://huggingface.co/Salesforce/codegen2-3_7B_P)

## Description

This is [codegen2-3_7B_P](https://huggingface.co/Salesforce/codegen2-3_7B_P) model converted to the [OpenVINO™ IR](https://docs.openvino.ai/2024/documentation/openvino-ir-format.html) (Intermediate Representation) format with weights compressed to int8 by [NNCF](https://github.com/openvinotoolkit/nncf).

## Quantization Parameters

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

* mode: **INT8_ASYM**
* sensitivity_metric: **weight_quantization_error**

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 2024.1.0 and higher
* Optimum Intel 1.16.0 and higher

## Running Model Inference with [Optimum Intel](https://huggingface.co/docs/optimum/intel/index)

1. Install packages required for using [Optimum Intel](https://huggingface.co/docs/optimum/intel/index) integration with the OpenVINO backend:

    ```
    pip install optimum[openvino]
    ```

2. Run model inference:

    ```
    from transformers import AutoTokenizer
    from optimum.intel.openvino import OVModelForCausalLM
    
    model_id = "OpenVINO/codegen2-3_7B_P-int8-ov"
    tokenizer = AutoTokenizer.from_pretrained(model_id)
    model = OVModelForCausalLM.from_pretrained(model_id)
    
    inputs = tokenizer("def print_hello_world():", return_tensors="pt")
    
    outputs = model.generate(**inputs, max_length=200)
    text = tokenizer.batch_decode(outputs)[0]
    print(text)
    ```

For more examples and possible optimizations, refer to the [OpenVINO Large Language Model Inference Guide](https://docs.openvino.ai/2024/learn-openvino/llm_inference_guide.html).

## 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/<model_name>"
model_path = "<model_name>"

hf_hub.snapshot_download(model_id, local_dir=model_path)

```

3. Run model inference:

```
import openvino_genai as ov_genai

device = "CPU"
pipe = ov_genai.LLMPipeline(model_path, device)
print(pipe.generate("def print_hello_world():"))
```

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)
