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
quantized_model_dir = "Intel/neural-chat-7b-v3-1-int4-inc"
model = AutoModelForCausalLM.from_pretrained(quantized_model_dir,
device_map="auto",
trust_remote_code=False,
use_neural_speed=False,
)
tokenizer = AutoTokenizer.from_pretrained(quantized_model_dir, use_fast=True)
print(tokenizer.decode(model.generate(**tokenizer("There is a girl who likes adventure,", return_tensors="pt").to(model.device),max_new_tokens=50)[0]))
"""
<s> There is a girl who likes adventure, who loves to travel, who is always looking for new experiences. She is a dreamer, a doer, a thinker, a believer. She is a girl who is not afraid to take risks, to make mistakes, to learn from
"""
INT4 Inference with AutoGPTQ
Install AutoGPTQ from source first
from transformers import AutoModelForCausalLM, AutoTokenizer
quantized_model_dir = "Intel/neural-chat-7b-v3-1-int4-inc"
model = AutoModelForCausalLM.from_pretrained(quantized_model_dir,
device_map="auto",
trust_remote_code=False,
)
tokenizer = AutoTokenizer.from_pretrained(quantized_model_dir, use_fast=True)
print(tokenizer.decode(model.generate(**tokenizer("There is a girl who likes adventure,", return_tensors="pt").to(model.device),max_new_tokens=50)[0]))
Evaluate the model
Install lm-eval-harness from source, we used the git id f3b7917091afba325af3980a35d8a6dcba03dc3f

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.
