+# Introduction
+ 🎉🎉🎉 We released the 360Zhinao2 model series:
+ - **360Zhinao2-7B-Base**
+ - **360Zhinao2-7B-Chat-4K**
+ - **360Zhinao2-7B-Chat-32K**
+ - **360Zhinao2-7B-Chat-360K**
+
+Notable features of our 360Zhinao models are:
+
+- **Base Model:** Using popular two-stage training method, In the first stage we totally train 10T tokens with a cosine learning rate schedule. In the second stage we increase the proportion of high-quality data and totally train 100B tokens, with the learning rate decaying directly to 0. The total training data for 360Zhinao2-7B amounts to 10.1T tokens.
+- **Chat Models:** Powerful chat capabilities and three context lengths of 4K, 32K and 360K. 
+
+<br>
+
+# News and Updates
+- [2024.11.18] 🔥🔥🔥We release 360Zhinao2-7B, providing access to both the Base model and Chat models with text lengths of 4K, 32K, and 360K.
+- [2024.05.23] We released two models, 360Zhinao-search and 360Zhinao-1.8B-Reranking, which ranked first respectively in the Retrieval and Reranking tasks of [C-MTEB Leaderboard](https://huggingface.co/spaces/mteb/leaderboard) .
+- [2024.05.20] We extended llama3 and released **llama3-8B-360Zhinao-360k-Instruct**<a href="https://huggingface.co/qihoo360/llama3-8B-360Zhinao-360k-Instruct">🤗</a>
+- [2024.04.12] We released **360Zhinao-7B** v1.0, including the base model and three chat models with context lengths 4K, 32K and 360K. 
+Technical report is on [arXiv](https://arxiv.org/abs/2405.13386).

+# Model Evaluation
+## Base Model
+We used the open-source tool OpenCompass to evaluate the model and compared it with open-source models under 10B from the past six months. The 360Zhinao2-7B model is competive. The 360Zhinao2-7B model performs well on Chinese benchmarks such as CEval, C3 and LCSTS. The average socres of Chinese benchmarks is No 1. It also ranks No 1 on Math which is a challenging competition math dataset. **The 360Zhinao2-7B model has advantages in Chinese benchmark and challenging competition math.**

+# Model Inference
+## Quantization
+We provide quantization schemes based on AutoGPTQ and release the Int4 quantization models. 
+
+## Deployment
+### vLLM Installation
+We recommend using `vLLM==0.3.3`.
+
+If you are using **CUDA 12.1 and PyTorch 2.1**, you can install vLLM directly with:
+```shell
+pip install vllm==0.3.3
+```
+
+Otherwise, please refer to the official vLLM [Installation Instructions](https://docs.vllm.ai/en/latest/getting_started/installation.html).
+
+After installation, perform the following steps:
+1. Copy `vllm/zhinao.py` into `vllm/model_executor/models` in your vllm installation directory (in python/conda env).
+2. Copy `vllm/serving_chat.py` into `vllm/entrypoints/openai` in your vllm installation directory.
+3. Then add a line in `vllm/model_executor/models/__init__.py`
+
+    ```shell
+    "ZhinaoForCausalLM": ("zhinao", "ZhinaoForCausalLM"),
+    ```
+
+### vLLM Service Start
+
+Start the service:
+```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
+```
+
+Use curl to request the service:
+```shell
+curl http://localhost:8360/v1/chat/completions \
+-H "Content-Type: application/json" \
+-d '{
+    "model": "360Zhinao2-7B-Chat-4K",

+        "<eod>",
+        "<|im_end|>",
+        "<|im_start|>"
+    ]
+}'
+```
+Use python to request the service:
+```python
+from openai import OpenAI
+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)
+```
+
+> If you need to enable repetition penalty, we recommend setting `presence_penalty` and `frequency_penalty` instead of `repetition_penalty`.

+- Configuring `HOSTFILE` switches between single-machine and multi-machine training.
+- configuring `ds_config` switches between zero1, zero2 and zero3.
+- `fp16, bf16` could configure mixed precision training. bf16 is recommended to be consistent with the pretrained model.
+- `is_concat` configures whether the training data is concatenated or not.

+# 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。
+
+<br>

+# 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 \

+    --max-model-len 4096 \
+    --host 0.0.0.0 \
+    --port 8360
+```
+

+
+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": [

+- 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。
