This repository contains the DISC-LawLLM-7B, version of Qwen2.5-7b-instuct as the base model.

Paper | Technical Report

DISC-LawLLM is a large language model specialized in Chinese legal domain, developed and open-sourced by Data Intelligence and Social Computing Lab of Fudan University (Fudan-DISC), to provide comprehensive intelligent legal services.

Quickstart

We advise you to install transformers>=4.37.0.

python

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

model = AutoModelForCausalLM.from_pretrained(
    "ShengbinYue/LawLLM-7B",
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("ShengbinYue/LawLLM-7B")

prompt = "生产销售假冒伪劣商品罪如何判刑？"
messages = [
    {"role": "system", "content": "你是LawLLM，一个由复旦大学DISC实验室创造的法律助手。"},
    {"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=512
)
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]

VLLM

Install vLLM pip install "vllm>=0.4.3"
Run LawLLM

python

from transformers import AutoModelForCausalLM, AutoTokenizer
from vllm import LLM, SamplingParams

model_name ='ShengbinYue/LawLLM-7B'

sampling_params = SamplingParams(
    temperature=0.1,
    top_p=0.9,
    top_k=50,
    max_tokens=4096
)
llm = LLM(model=model_name)

tokenizer = AutoTokenizer.from_pretrained(model_name)
prompt =  "生产销售假冒伪劣商品罪如何判刑？"

# prompt = "戴罪立功是什么意思"
messages = [
    {"role": "system", "content": "你是LawLLM，一个由复旦大学DISC实验室创造的法律助手。"},
    {"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

outputs = llm.generate([text], sampling_params)
for output in outputs:
    prompt = output.prompt
    generated_text = output.outputs[0].text
    print(f"Prompt: {prompt!r}, Generated text: {generated_text!r}")
