+# Tongyi-Finance-14B
+
+## 介绍 (Introduction)
+
+**通义金融-14B**（**Tongyi-Finance-14B**）是针对对金融行业推出的大语言模型，基于通义千问基础模型进行行业语料增量学习，强化金融领域知识和场景应用能力，覆盖金融知识问答、文本分类、信息抽取、文本创作、阅读理解、逻辑推理、多模态、Coding等能力象限。
+
+通义金融-14B（Tongyi-Finance-14B）有以下特点：
+
+1. **行业语料增量学习**：使用200B高质量金融行业语料进行增量学习，并进行金融行业词表扩展，覆盖丰富的数据类型，支持更大上下文（16k）输入和完整的语义表达。
+2. **行业能力强化**：自研SFT质量&多样性分析工具，筛选高质量SFT数据，解决大语言模型的alignment问题。
+3. **行业后链路优化**：借助multi-agent框架，实现知识库增强和工具API调用。
+
+<br>
+
+## 要求（Requirements）和 依赖项 (Dependency)
+* python 3.8及以上版本
+* pytorch 1.12及以上版本，推荐2.0及以上版本
+* 建议使用CUDA 11.4及以上（GPU用户、flash-attention用户等需考虑此选项）
+<br>
+请确保满足上述要求，再执行以下pip命令安装依赖库
+
+```bash
+pip install transformers_stream_generator==0.0.4
+pip install modelscope>=1.9.0
+pip install transformers>=4.32.0
+```
+
+另外，推荐安装`flash-attention`库，以实现更高的效率和更低的显存占用。
+
+```bash
+git clone -b v1.0.8 https://github.com/Dao-AILab/flash-attention
+cd flash-attention && pip install .
+# 下方安装可选，安装可能比较缓慢。
+# Below are optional. Installing them might be slow.
+# pip install csrc/layer_norm
+# pip install csrc/rotary
+```
+<br>
+
+更详细的要求和依赖项内容请参考基座模型[通义千问-14B](https://modelscope.cn/models/qwen/Qwen-14B)仓库。
+
+## 快速使用（Quickstart）
+
+您可以通过以下代码轻松调用：
+
+```python
+from modelscope import AutoModelForCausalLM, AutoTokenizer, snapshot_download
+from modelscope import GenerationConfig
+
+model_dir = snapshot_download('TongyiFinance/Tongyi-Finance-14B')
+
+# Note: The default behavior now has injection attack prevention off.
+tokenizer = AutoTokenizer.from_pretrained(model_dir, trust_remote_code=True)
+
+# use bf16
+# model = AutoModelForCausalLM.from_pretrained(model_dir, device_map="cuda:0", trust_remote_code=True, bf16=True).eval()
+# use cpu only
+# model = AutoModelForCausalLM.from_pretrained(model_dir, device_map="cpu", trust_remote_code=True).eval()
+model = AutoModelForCausalLM.from_pretrained(model_dir, device_map="cuda:0", trust_remote_code=True).eval()
+# 模型加载指定device_map='cuda:0'，更改成device_map='auto'会使用所有可用显卡
+
+# Specify hyperparameters for generation
+model.generation_config = GenerationConfig.from_pretrained(model_dir, trust_remote_code=True)
+
+inputs = tokenizer('市盈率是最常用来评估股价水平是否合理的指标之一，是指', return_tensors='pt')
+inputs = inputs.to(model.device)
+pred = model.generate(**inputs)
+print(tokenizer.decode(pred.cpu()[0], skip_special_tokens=True))
+# 市盈率是最常用来评估股价水平是否合理的指标之一，是指股票价格与每股盈利的比率。...
+```
+
+<br>
+
+## 模型细节 (Model)
+
+通义金融-14B模型规模基本情况如下所示：
+
+| Hyperparameter  |  Value |
+|:----------------|:-------|
+|    n_layers     |     40 |
+|     n_heads     |     40 |
+|     d_model     |   5120 |
+|   vocab size    | 154112 |
+| sequence length |  16384 |
+
+在位置编码、FFN激活函数和normalization的实现方式上，我们也采用了目前最流行的做法，
+即RoPE相对位置编码、SwiGLU激活函数、RMSNorm（可选安装flash-attention加速）。
+
+在分词器方面，相比目前主流开源模型以中英词表为主，Tongyi-Finance-14B在Qwen-14B扩展了金融行业词汇，词表大小15万。 该词表在GPT-4使用的BPE词表`cl100k_base`基础上，对中文、多语言进行了优化，在对中、英、代码数据的高效编解码的基础上，对部分多语言更加友好，方便用户在不扩展词表的情况下对部分语种进行能力增强。
+词表对数字按单个数字位切分。调用较为高效的[tiktoken分词库](https://github.com/openai/tiktoken)进行分词。
+
+<br>
+
+## 使用协议（License Agreement）
+
+我们的代码和模型权重对学术研究完全开放，并支持商用。请查看[LICENSE](https://modelscope.cn/models/TongyiFinance/Tongyi-Finance-14B/file/view/master/LICENSE.md)了解具体的开源协议细节。
+
