📖 Introduction

Qwen2-7B-Instruct-Refine and Qwen2-1.5B-Instruct-Refine are two powerful large language models that act as proficient prompt engineers. They can optimize and refine the prompts input by users, and the generated optimized instructions can significantly enhance the LLM's ability to produce better and more informative responses for users.

We fine-tuned Qwen2-7B-Instruct and Qwen2-1.5B-Instruct to obtain Qwen2-7B-Instruct-Refine and Qwen2-1.5B-Instruct-Refine. We sampled the dataset from OpenHermes and the LCCD dataset, ensuring a balanced task distribution. For training set annotations, we used Qwen-max with incorporated our handwritten examples as in-context prompts.

🚀 Quick Start

Here provides a code snippet with apply_chat_template to show you how to load the tokenizer and model and how to generate contents.

python

from transformers import AutoModelForCausalLM, AutoTokenizer
device = "cuda" # the device to load the model onto

model = AutoModelForCausalLM.from_pretrained(
    "alibaba-pai/Qwen2-1.5B-Instruct-Refine",
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("alibaba-pai/Qwen2-1.5B-Instruct-Refine")

prompt = "Give me a short introduction to large language model."
messages = [
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(device)

generated_ids = model.generate(
    model_inputs.input_ids,
    max_new_tokens=2048，
    eos_token_id=151645，
)
generated_ids = [
    output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]

response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]

🔍 Evaluation

We used single-turn instructions from MT-Bench as input for Qwen2-1.5B-Instruct and Qwen2-7B-Instruct. GPT4-turbo is used to evaluate the changes in the level of detail and truthfulness of responses to our model's revised instructions.

Model	Detail	Truthfulness
Qwen2-1.5B-Instruct	50.00%	50.00%
+ Qwen2-1.5B-Instruct-Refine	75.63%	63.75%
+ Qwen2-7B-Instruct-Refine	76.56%	62.19%
Qwen2-7B-Instruct	50.00%	50.00%
+ Qwen2-1.5B-Instruct-Refine	70.94%	57.19%
+ Qwen2-7B-Instruct-Refine	74.69%	58.44%
