Model Details

This model is an int4 model with group_size 128 and symmetric quantization of tencent/Hy-MT2-1.8B generated by intel/auto-round. Please follow the license of the original model.

How to Use

HF Usage

uv pip install transformers>=5.6.0 auto-round

python

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model_path = "Intel/Hy-MT2-1.8B-int4-AutoRound"

# Load tokenizer
tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True)

# Load model
model = AutoModelForCausalLM.from_pretrained(
    model_path,
    dtype=torch.bfloat16,
    device_map="auto",
    trust_remote_code=True,
)

model.eval()

# Example inference
prompt = "将以下文本翻译成英语,注意只需要输出翻译后的结果,不要额外解释:\n\n今天天气真好。"
messages = [{"role": "user", "content": prompt}]
inputs = tokenizer.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)

with torch.no_grad():
    outputs = model.generate(
        **inputs,
        max_new_tokens=4096,
    )
response = tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:], skip_special_tokens=True)
print(response)

VLLM Usage

bash

vllm serve Intel/Hy-MT2-1.8B-int4-AutoRound \
    --host localhost \
    --trust-remote-code \
    --dtype bfloat16

Generate the Model

auto-round --model_name tencent/Hy-MT2-1.8B --bits 4 --iters 200 --output_dir Hy-MT2-1.8B-int4-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. Here are a couple of useful links to learn more about Intel's AI software:
