源2.0 是浪潮信息发布的新一代基础语言大模型。我们开源了全部的3个模型源2.0-102B，源2.0-51B和源2.0-2B。并且我们提供了预训练，微调，推理服务的相关脚本，以供研发人员做进一步的开发。源2.0是在源1.0的基础上，利用更多样的高质量预训练数据和指令微调数据集，令模型在语义、数学、推理、代码、知识等不同方面具备更强的理解能力。

Yuan2.0 is a new generation Fundamental Large Language Model developed by IEIT System. We have published all three models, Yuan 2.0-102B, Yuan 2.0-51B, and Yuan 2.0-2B. And we provide relevant scripts for pretraining, fine-tuning, and inference services for other developers. Yuan2.0 is based on Yuan1.0, utilizing a wider range of high-quality pre training data and instruction fine-tuning datasets to enhance the model's understanding of semantics, mathematics, reasoning, code, knowledge, and other aspects.

代码调用/Code Usage

可以通过如下代码调用 Yuan2-2B 模型来生成文本：

You can generate text by invoking the Yuan2-2B model with the following code:

python

import torch, transformers
import sys, os
sys.path.append(
    os.path.abspath(os.path.join(os.path.dirname(__file__), os.path.pardir)))
from transformers import AutoModelForCausalLM,AutoTokenizer,LlamaTokenizer

print("Creat tokenizer...")
tokenizer = LlamaTokenizer.from_pretrained('IEITYuan/Yuan2-2B-Janus-hf', add_eos_token=False, add_bos_token=False, eos_token='<eod>')
tokenizer.add_tokens(['<sep>', '<pad>', '<mask>', '<predict>', '<FIM_SUFFIX>', '<FIM_PREFIX>', '<FIM_MIDDLE>','<commit_before>','<commit_msg>','<commit_after>','<jupyter_start>','<jupyter_text>','<jupyter_code>','<jupyter_output>','<empty_output>'], special_tokens=True)

print("Creat model...")
model = AutoModelForCausalLM.from_pretrained('IEITYuan/Yuan2-2B-hf', device_map='auto', torch_dtype=torch.bfloat16, trust_remote_code=True)

inputs = tokenizer("请问目前最先进的机器学习算法有哪些？", return_tensors="pt")["input_ids"].to("cuda:0")
outputs = model.generate(inputs,do_sample=False,max_length=100)
print(tokenizer.decode(outputs[0]))

Benchmark评估/Benchmark Evaluation

我们提供了HumanEval，AGIEval-GK-Math，GSM8K和TruthfulQA的评估脚本。在4个典型任务上，我们用源2.0不同版本模型上进行了性能测试。

We have provided evaluation scripts for HumanEval,AGIEval-GK-Math,GSM8K and TruthfulQA. Performance tests were conducted on different versions of the Yuan2.0 model for four typical tasks.

Model	GSM8K	AGIEval-GK-Math-QA	AGIEval-GK-Math-Cloze	HumanEval	TurthfulQA
GPT-4	92%	47.0%	16.1%	86.6%	59%
ChatGPT	68.6%*	36.5%	7.3%	66.5%*	34%*
Llama2	56.8%	-	-	29.9%	-
源2.0-102B	76.6%	38.7%	13.5%	67.1%	58%
源2.0-102B-SC	86.2%	45.5%	15.2%	77.4%	-

* 使用与源2.0完全相同的输入数据对ChatGPT进行测试，时间2023年11月

* Testing ChatGPT using the same input data as Yuan2.0, as of November 2023.
