# 模型介绍 |
|
🎉🎉🎉我们开源了360智脑大模型的系列工作，本次开源了以下模型： |
|
- **360Zhinao2-7B-Base** |
|
- **360Zhinao2-7B-Chat-4K** |
|
- **360Zhinao2-7B-Chat-32K** |
|
- **360Zhinao2-7B-Chat-360K** |
|
|
|
360智脑大模型特点如下： |
|
- **基础模型**：采⽤当前主流的两阶段训练⽅法，第⼀阶段采用cosine学习率总共训练10T |
|
token，第二阶段我们加⼤了⾼质量数据的占⽐，训练了100B⾼质量token，学习率LR直接decay到0。**360Zhinao2-7B总共训练数据量达10.1T token**。 |
|
- **对话模型**：具有强大的对话能力，开放4K、32K、360K三种不同文本长度。 |
|

## Chat模型 |
|
|
|
### 后训练数据 |
|
360自有通用微调数据50w，该数据综合考虑各个技能及360垂直业务数据，生成方法如下： |
|
1. 数据多样性：根据360自有标签体系进行领域，意图，难度，长度的分层采样，确保指令多样性 |
|
2. 数据质量：使用开源数据以及自有的偏序数据训练了360gpt-pro-rm（reward bench得分92.59），使用该模型进行样本筛选，过滤response低质数据 |
|
3. 复杂指令进化：使用进化方式做复杂指令优化，优化指令跟随能力 |
|
|
|
### 训练方法 |
|
1. 全参数微调 |
|
|
|
基于通用后训练数据，进行全参数微调,选择最优checkpoint作为sft-base。 |
|
|
|
2. Lora offline DPO强化 |
|
|
|
使用人类标注好的偏好pair对，采用Lora方法对sft-base进行lora微调，然后进行lora DPO训练。 |
|
|
|
3. Iterative on-policy DPO 全参数强化 |
|
|
|
使用sft-base模型在训练prompt上采样多个答案，用360gpt-pro-rm打分，取最高最低分组pair进行DPO训练。我们迭代地使用这种on-policy DPO提升模型效果。 |
|
|
|
4. 模型合并 |
|
|
|
在360公司白盒评测集合4上，针对上述3个模型做自动评测，发现不同模型各有其又是技能，考虑模型合并方案。基于sft模型为base做内插得到模型v1，然后仍以sft模型为base和v1模型进行外插，外插系数0.2 最终得到360Zhicao2-7B-Chat-4k. |
|
|
|
### 模型效果 |
|
我们在一些经典任务上对 360Zhicao2-7B-Chat-4k 模型进行了评测。IFEval (prompt strict) 仅次于GLM4-9B,7b开源模型最高；MT-bench第3名略差于Qwen2.5-7B,7B模型排名第二；CF-Bench第3，在PSR上仅次于GLM4-9B,详细结果如下表: |
|
|
|
| Model | MT-bench | IFEval(strict prompt) | CFBench(CSR,ISR,PSR) | | | |
|
|----------------------|----------|-----------------------|----------------------|------|------| |
|
| Qwen2.5-7B-Instruct | **8.07** | 0.556 | **0.81** | 0.46 | 0.57 | |
|
| Yi-9B-16k-Chat | 7.44 | 0.455 | 0.75 | 0.4 | 0.52 | |
|
| GLM4-9B-Chat | **8.08** | **0.634** | **0.82** | 0.48 | 0.61 | |
|
| InternLM2.5-7B-Chat | 7.39 | 0.540 | 0.78 | 0.4 | 0.54 | |
|
| 360Zhicao2-7B-Chat-4k| 7.86 | **0.577** | 0.8 | 0.44 | 0.57 | |
|
|
|
|
|
|
|
### 长文本微调 |
|
与360Zhinao1开源时的做法基本一致，我们将RoPE base依次扩大为1000,000和50,000,000，混合长短文本的SFT数据依次拼接至32k和360k，将gradient checkpointing、ZeRO3 offload和ring attention等技术结合，依次微调得到32k和360k长文本模型。在各个32k benchmark上位列第一梯队。 |
|
|
|
| Model | LooGLE-长依赖QA | Loong-Set 1 (32k) | LongBench-Chat (32k截断) | LEval-96题子集胜率 | LEval-客观题均分 | |
|
|------------------------------|-----------------|-------------------|--------------------------|--------------------|------------------| |
|
| GLM4-9B-Chat | 0.36 | 55.24 | 6.60 | 0.49 | 63.96 | |
|
| InternLM2.5-7B-Chat | 0.39 | 42.76 | 5.70 | 0.44 | 61.64 | |
|
| 360Zhinao2-7B-Chat-32k | 0.33 | 39.37 | 5.44 | 0.44 | 60.48 | |
|
| 360Zhinao2-7B-Chat-360k | 0.34 | 32.16 | 5.08 | 0.38 | 53.00 | |
|
| Yi-1.5-9B-Chat | 0.25 | 32.77 | 4.70 | 0.37 | 56.22 | |

# 模型推理 |
|
## 模型量化 |
|
我们提供了基于AutoGPTQ的量化方案，并开源了Int4量化模型。 |
|
|
|
## 模型部署 |
|
### vLLM安装环境 |
|
如希望部署及加速推理，我们建议你使用 `vLLM==0.3.3`。 |
|
|
|
如果你使用**CUDA 12.1和PyTorch 2.1**，可以直接使用以下命令安装vLLM。 |
|
```shell |
|
pip install vllm==0.3.3 |
|
``` |
|
|
|
否则请参考vLLM官方的[安装说明](https://docs.vllm.ai/en/latest/getting_started/installation.html)。 |
|
|
|
>安装完成后，还需要以下操作~ |
|
1. 把vllm/zhinao.py文件复制到env环境对应的vllm/model_executor/models目录下。 |
|
2. 把vllm/serving_chat.py文件复制到env环境对应的vllm/entrypoints/openai目录下。 |
|
3. 然后在vllm/model_executor/models/\_\_init\_\_.py文件增加一行代码 |
|
|
|
```shell |
|
"ZhinaoForCausalLM": ("zhinao", "ZhinaoForCausalLM"), |
|
``` |
|
|
|
### vLLM服务启动 |
|
|
|
启动服务 |
|
```shell |
|
python -m vllm.entrypoints.openai.api_server \ |
|
--served-model-name 360Zhinao2-7B-Chat-4K \ |
|
--model qihoo360/360Zhinao2-7B-Chat-4K \ |
|
--trust-remote-code \ |
|
--tensor-parallel-size 1 \ |
|
--max-model-len 4096 \ |
|
--host 0.0.0.0 \ |
|
--port 8360 |
|
``` |
|
|
|
使用curl请求服务 |
|
```shell |
|
curl http://localhost:8360/v1/chat/completions \ |
|
-H "Content-Type: application/json" \ |
|
-d '{ |
|
"model": "360Zhinao2-7B-Chat-4K", |
|
"max_tokens": 200, |
|
"top_k": -1, |
|
"top_p": 0.8, |
|
"temperature": 1.0, |
|
"presence_penalty": 0.0, |
|
"frequency_penalty": 0.0, |
|
"messages": [ |
|
{"role": "system", "content": "You are a helpful assistant."}, |
|
{"role": "user", "content": "你好"} |
|
], |
|
"stop": [ |
|
"<eod>", |
|
"<|im_end|>", |
|
"<|im_start|>" |
|
] |
|
}' |
|
``` |
|
使用python请求服务 |
|
```python |
|
from openai import OpenAI |
|
# Set OpenAI's API key and API base to use vLLM's API server. |
|
openai_api_key = "EMPTY" |
|
openai_api_base = "http://localhost:8360/v1" |
|
|
|
client = OpenAI( |
|
api_key=openai_api_key, |
|
base_url=openai_api_base, |
|
) |
|
|
|
chat_response = client.chat.completions.create( |
|
model="360Zhinao2-7B-Chat-4K", |
|
messages=[ |
|
{"role": "system", "content": "You are a helpful assistant."}, |
|
{"role": "user", "content": "你好"}, |
|
], |
|
stop=[ |
|
"<eod>", |
|
"<|im_end|>", |
|
"<|im_start|>" |
|
], |
|
presence_penalty=0.0, |
|
frequency_penalty=0.0 |
|
) |
|
print("Chat response:", chat_response) |
|
``` |
|
|
|
> 注意：如需要开启重复惩罚，建议使用 *presence_penalty* 和 *frequency_penalty* 参数。 |

# 模型微调 |
|
## 训练数据 |
|
|
|
我们提供了微调训练样例数据 data/test.json，该样例数据是从 [multiturn_chat_0.8M](https://huggingface.co/datasets/BelleGroup/multiturn_chat_0.8M) 采样出 1 万条，并且做了格式转换。 |
|
|
|
数据格式: |
|
```json |
|
[ |
|
{ |
|
"id": 1, |
|
"conversations": [ |
|
{ |
|
"from": "system", |
|
"value": "You are a helpful assistant." |
|
}, |
|
{ |
|
"from": "user", |
|
"value": "您好啊" |
|
}, |
|
{ |
|
"from": "assistant", |
|
"value": "你好！我今天能为您做些什么？有什么问题或需要帮助吗? 我在这里为您提供服务。" |
|

|
- 可通过配置hostfile，实现单机、多机训练。 |
|
- 可通过配置ds_config，实现zero2、zero3。 |
|
- 可通过配置fp16、bf16实现混合精度训练，建议使用bf16，与预训练模型保持一致。 |
|
- 可通过配置is_concat参数，控制训练数据是否拼接，当训练数据量级较大时，可通过拼接提升训练效率。 |
