Please note that due to the ongoing development of the project, the model weights in this repository may differ from those in our currently deployed demo.

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. The advtantages is:

• Legal Texts Generic Processing Capability
• Legal Thinking and Reasoning
• Legal knowledge Retrieval Capacity

In addition, the contributions include:

• High-quality SFT datasets and effective training paradigms
• Chinese legal LLMs evaluation framework

Check our HOME for more information.

DISC-Law-SFT Dataset

we construct a high-quality supervised fine-tuning dataset, DISC-Law-SFT with two subsets, namely DISC-Law-SFT-Pair and DISC-Law-SFT-Triplet. Our dataset converge a range of legal tasks, including legal information extraction, judgment prediction, document summarization, and legal question answering, ensuring coverage of diverse scenarios. <img src="" alt="" width=""/>

Using through hugging face transformers

>>>import torch
>>>>>>from transformers import AutoModelForCausalLM, AutoTokenizer
>>>from transformers.generation.utils import GenerationConfig
>>>tokenizer = AutoTokenizer.from_pretrained("ShengbinYue/DISC-LawLLM", use_fast=False, trust_remote_code=True)
>>>model = AutoModelForCausalLM.from_pretrained("ShengbinYue/DISC-LawLLM", device_map="auto", torch_dtype=torch.float16, trust_remote_code=True)
>>>model.generation_config = GenerationConfig.from_pretrained("ShengbinYue/DISC-LawLLM")
>>>messages = []
>>>messages.append({"role": "user", "content": "生产销售假冒伪劣商品罪如何判刑？"})
>>>response = model.chat(tokenizer, messages)
>>>print(response)

Disclaimer

DISC-LawLLM comes with issues and limitations that current LLMs have yet to overcome. While it can provide Chinese legal services in many a wide variety of tasks and scenarios, the model should be used for reference purposes only and cannot replace professional lawyers and legal experts. We encourage users of DISC-LawLLM to evaluate the model critically. We do not take responsibility for any issues, risks, or adverse consequences that may arise from the use of DISC-LawLLM.
