codegen2-3_7B_P-int8-ov

• Model creator: Salesforce
• Original model: codegen2-3_7B_P

Description

This is codegen2-3_7B_P model converted to the OpenVINO™ IR (Intermediate Representation) format with weights compressed to int8 by 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.

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

1. Install packages required for using Optimum Intel 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("What is OpenVINO?", 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.
