 - System Prompt: pin a user defined prompt as system prompt 为每个对话设置系统 Prompt [#138](https://github.com/Yidadaa/ChatGPT-Next-Web/issues/138)
 - User Prompt: user can edit and save custom prompts to prompt list 允许用户自行编辑内置 Prompt 列表
 - Self-host Model: support llama, alpaca, ChatGLM, BELLE etc. 支持自部署的大语言模型
 - Plugins: support network search, caculator, any other apis etc. 插件机制，支持联网搜索、计算器、调用其他平台 api [#165](https://github.com/Yidadaa/ChatGPT-Next-Web/issues/165)
