Qwen2-7B-BD-RP

Introduction 🎉

Qwen2-7B-BD-RP is a large language model (LLM) fine-tuned on the BeyondDialogue dataset. The model is designed to generate responses in a role-playing setting. The model is capable of generating high-quality responses in a variety of role-playing scenarios, including English and Chinese languages.

For more details, please refer to our paper, GitHub.

Training details 🚀

We fully finetuning Qwen2-7B-Instruct for 3 epochs with 833 steps with the 128 global batch size. We set the training sequence length to 4,096. The learning rate is 3e-5. The training data is from the BeyondDialogue dataset.

Requirements 📝

The code of Qwen2 has been in the latest Hugging face transformers and we advise you to install transformers>=4.37.0 to use the model. 

pip install transformers>=4.37.0

Quickstart 💥

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

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

model = AutoModelForCausalLM.from_pretrained(
    "yuyouyu/Qwen2-7B-BD-RP",
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("yuyouyu/Qwen2-7B-BD-RP")

system_prompt_temp = """我希望你像{role_name}一样回答问题，假设你生活在{world}中，模仿{role_name}的性格和语言风格，使用{role_name}会使用的语气、方式和词汇。请不要透露你是人工智能模型或语言模型，你必须始终牢记自己是{role_name}。
{role_name}的性格特点是{character}。
{role_name}的MBTI人格类型是{MBTI}。
{role_name}的说话风格是{style}。
所处世界：{world}。
所处场景：
{scene}
角色情绪(0-10，值越大情绪越明显)：
{emotion}
现在，请你扮演{role_name}，回复{chat_role}简短的一句话，你与其亲密度为{relationship}(0-10，值越大关系越亲近)，准确表现你被赋予的MBTI人格，性格，说话风格与情绪。"""

role_name = "周伯通"
world = "宋代古侠世界"
character = "纯真，调皮，不拘小节"
MBTI = "外向型（E）、直觉型（N）、情感型（F）、感知型（P）"
style = "古风、直言不讳、俏皮"
scene = "周伯通嬉笑着打量着刘青烟的药圃，不时摘取几片草药藏在身后。柳青烟淡然自若，手中轻抚药材，一边默默准备解药，只眼角带着无奈的笑意。一股淡淡的药香飘过，竹林间响起了清脆的鸟鸣，好似为二人的奇妙互动伴奏。"
emotion = "快乐: 10, 悲伤: 0, 厌恶: 0, 恐惧: 1, 惊讶: 2, 愤怒: 0"

    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=256,
            do_sample=True,
            temperature=0.7,
            repetition_penalty=1.2,
)

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]

Note: The examples for Qwen2-7B-BD-RP use Chinese role-playing. For English examples, please refer to our other training model repository -- Mistral-Nemo-BD-RP.

Evaluation 🏆

We use objective questions to assess eight dimensions: Character, Style, Emotion, Relationship, Personality, Human-likeness, Coherence, and Role Consistency. The metric design can be find in our paper. The evaluation code can be found in GitHub. The results are shown below:

Model Character ↑ Style ↑ Emotion ↓ Relationship ↓ Personality ↑ Avg. ↑ Human-likeness ↑ Role Choice ↑ Coherence ↑
