能否分别统计和显示问答字数

**Is your feature request related to a problem? Please describe.**
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
问题多少字，回答多少字，回答字数=大模型最直观的性能展示
多个智能大模型的回答字数/问题字数=，本地客户端计算数字，数字越大越好
目前通义老是没有回答等待其它 通义千问 请求结束…

我看到有的ChatGPT客户端有显示预估 Token 字数统计，
可以设置上下文中的最大 Token 数、每个回复的最大 Token 数
好大致估算费用
