+# CogAgent
+
+## 1. 模型介绍
+
+该模型是 [CogAgent](https://arxiv.org/abs/2312.08914) 的 paddle 实现。
+
+[CogAgent](https://arxiv.org/abs/2312.08914)是一个基于CogVLM改进的开源视觉语言模型。CogAgent-18B拥有110亿的视觉参数和70亿的语言参数。
+
+CogAgent-18B在9个经典的跨模态基准测试中实现了最先进的全能性能，包括VQAv2、OK-VQ、TextVQA、ST-VQA、ChartQA、infoVQA、DocVQA、MM-Vet和POPE。
+
+除了CogVLM已有的所有功能（视觉多轮对话，视觉定位）之外，CogAgent：
+
+1. 支持更高分辨率的视觉输入和对话式问答。它支持超高分辨率的图像输入，达到1120x1120。
+
+2. 拥有视觉Agent的能力，能够在任何图形用户界面截图上，为任何给定任务返回一个计划，下一步行动，以及带有坐标的特定操作。
+
+3. 增强了与图形用户界面相关的问答能力，使其能够处理关于任何图形用户界面截图的问题，例如网页、PC应用、移动应用等。
+
+4. 通过改进预训练和微调，提高了OCR相关任务的能力。
+
+本仓库提供paddle版本的 cogagent-chat 模型
+
+## 2. 环境准备
+
+1） [安装PaddleNLP](https://github.com/PaddlePaddle/PaddleNLP?tab=readme-ov-file#%E5%AE%89%E8%A3%85)
+
+2）[安装 PaddleMix 环境依赖包](https://github.com/PaddlePaddle/PaddleMIX/tree/b4f97ff859e1964c839fc5fab94f7ba63b1e5959?tab=readme-ov-file#%E5%AE%89%E8%A3%85)
+
+## 3. 快速开始
+完成环境准备后，我们目前提供多轮对话方式使用：
+
+```bash
+python paddlemix/examples/cogagent/chat_demo.py \
+--from_pretrained "THUDM/cogagent-chat"
+```
+
+可配置参数说明：
+  * `from_pretrained`: 指定CogAgent的模型名字或权重路径以及tokenizer，默认 THUDM/cogagent-chat
