目录
刚刚开始写CSDN,下班了研究研究CSDN的玩法,看到活动区发起了“Agent AI智能体的未来”话题,正好最近工作中比较多的经历集中在这里,所以借着这个话题活动写一些自己的看法。
目前的工作总结来看就是进行AI智能体的开发,组里基于langchain做了一些储备,搭建了内部的一个AI智能体开发平台,支持了知识库、工具调用、多种大模型的配置,但当后来字节的coze、百度的千帆发布,发现AI智能体开发平台真是发展的太快了,相比于coze,丰富的插件工具,稳定的模型,成熟的工作流,分析自己组内的人力情况,根本追不上:组内同学既要全力完成okr,又要每个人开发自己的AI智能体,剩下的精力才能继续完善AI智能体平台。
五一之前,领导在群里扔了一个创业公司基于Dify开发AI应用的介绍。我抱着学习的态度了解了一下Dify:可以称之为开源版的coze!支持多种大模型、插件工具的一键适配,支持知识库自动切割创建索引,支持工具流开发!赞啊,这些功能不正是组内AI智能体开发平台需要添加的功能么。于是马上开始了部署与调试。
先分享dify项目的github:https://github.com/langgenius/dify
“项目由前腾讯云DevOps团队成员创建。我们发现基于OpenAI的API开发GPT应用程序有些麻烦。凭借我们多年在开发者效率工具方面的研发经验,我们希望能够让更多的人使用自然语言开发有趣的应用程序。”
dify由10+全职团队和100+社区贡献者共同维护,迭代非常快,我下载的时候还是0.6.3,现在已经升级为0.6.6,基本上每周都会升级一个版本。这里唠叨两句,对于迭代非常频繁的开源项目,在公司内部使用的时候,咱就先别二次开发了,否则你这边刚开发完一个点,另一边社区升级了,逻辑冲突合不到一块去,尴尬不尴尬。之前听说有个团队基于tensorflow1.x“自研”了深度学习训练框架,多年过去,社区都2.x了,那个团队还在tensorflow1.x上疲于奔命。哈哈哈,扯远了。
说回到本文,标题叫《Agent AI智能体的未来—Dify项目介绍》,其实是有些夸张的,但我认为,了解Dify以及其中依赖的上下游技术、架构,利用Dify快速建立AI智能体demo原型,其实对推进AI智能体开发是有意义的。今天我先简要介绍一下Dify的部署过程,后面的篇幅会具体分享基于Dify的AI智能体开发经验,以及AI智能体开发所依赖的底层技术。
首先将dify项目下载至服务器上,
git clone https://github.com/langgenius/dify.git
项目主要分为api(后端)和web(前端)两大部分,具体代码后面再分析,进入docker目录
cd docker
目录中包含几个文件,docker-compose.yaml可以通过docker compose直接启动所有服务和依赖,docker-compose.middleware.yaml可以先启动依赖的关系数据库、向量数据库等组件,再单独启动api和web端,隔离做得可以说太棒了。
先看一下docker-compose.yaml的源码

主要包含如下几个模块及docker镜像
docker compose一键部署安装
docker compose up -d
从dockerhub逐个pulling依赖镜像,感觉还挺爽的
等待镜像下载部署完成后,打开webui:123.123.123.123:80,默认占用80端口,可以在docker compose配置文件中更改nignx端口。
经过账号初始化等工作后,欢迎来到Dify工作界面,就是这么丝滑
相较于fastGPT+oneApi的方案,集成度更高:
Dify内置了包含搜索引擎、天气预报、维基百科、SD等工具,同时自定义工具的配置化接入,团队成员一人接入,全组复用,高效!
只需连接各个节点,既能在几分钟内快速完成AI智能体创作,且逻辑非常清晰。
编写提示词,导入知识库,添加工具,选择模型,运行测试,发布为API,一条龙创作!
还有很多特色,在此不再赘述了,附上一张官方的表格吧
临下班了,本来只是想参加个话题活动,洋洋洒洒几千字。可能加入了太多感慨吧。希望感兴趣的朋友可以关注我、点赞、收藏和评论,您的鼓励是我持续码字的动力。
本文首先结合自己的工作写了一些对Agent AI智能体的见解,接着介绍了Dify框架快捷部署的过程,最后阐述了Dify框架的特点。个人认为Dify的发展会让Agent AI智能体开发提效,涌现更多有趣有价值的AI应用。
最后,写一下我对未来AI智能体发展的看法吧,从流量与用户来看,2000年-2004年,以新浪、搜狐、网易为代表的门户网站是流量入口,2004年-2014年,以百度为代表的搜索引擎是流量入口,2014-2024,以抖音、快手、微博、小红书为代表的移动互联网推荐系统是流量入口,抓住了流量入口就抓住了用户,抓住了用户就抓住了商业变现。2024-未来,极大的可能出现一家基于AI的平台型企业,通过AI智能体抓住流量,比如你要去哪玩,AI智能体在为你做出规划的过程中,夹杂酒店、航班的广告私货,你想吃什么,AI智能体夹杂着饭店的广告私货。
AI领域,乾坤未定,你我皆是黑马。
