  • 支持开关指定插件

  • 支持添加自定义插件

  • 支持 Agent 参数配置( agentType, maxIterations, returnIntermediateSteps 等)

  • 支持 ChatSession 级别插件功能开关

已知问题

  • 使用插件时需将模型切换为 0613 版本模型,如:gpt-3.5-turbo-0613
  • SERPAPI_API_KEY 目前为必填,后续会支持使用 DuckDuckGo 替换搜索插件
  • Agent 不支持自定义接口地址
  • 部分场景下插件会调用失败
  • 插件调用失败后无反馈

Keep Updated

简体中文 > 如何保持代码更新

If you have deployed your own project with just one click following the steps above, you may encounter the issue of "Updates Available" constantly showing up. This is because Vercel will create a new project for you by default instead of forking this project, resulting in the inability to detect updates correctly.

We recommend that you follow the steps below to re-deploy:

  • Delete the original repository;
  • Use the fork button in the upper right corner of the page to fork this project;
  • Choose and deploy in Vercel again, please see the detailed tutorial.

Enable Automatic Updates

If you encounter a failure of Upstream Sync execution, please manually sync fork once.

After forking the project, due to the limitations imposed by GitHub, you need to manually enable Workflows and Upstream Sync Action on the Actions page of the forked project. Once enabled, automatic updates will be scheduled every hour:

Manually Updating Code

If you want to update instantly, you can check out the GitHub documentation to learn how to synchronize a forked project with upstream code.

You can star or watch this project or follow author to get release notifictions in time.

Access Password

简体中文 > 如何增加访问密码

This project provides limited access control. Please add an environment variable named CODE on the vercel environment variables page. The value should be passwords separated by comma like this:

code1,code2,code3

After adding or modifying this environment variable, please redeploy the project for the changes to take effect.
