Vercel部署此路有严重限制，玩玩就好，真用还是得docker。

还是看看远处的aurora吧家人们

• 限制原因: Vercel的流式响应并不是一开始写流，客户端就能立刻收到响应流，而是先写到一个缓冲区，当流关闭才一股脑的流式响应回来(不是实时流)
• 因此导致: 超过10s之后才要关闭的流，通通接收不到。(因为Vercel免费版持续时间最大值10秒)
• 解决办法: 氪金!!! Vercel Pro 超时上限为300s，Pro用户部署完成后，到Vercel的Setting->Git->Production Branch填写为vercel-pro然后Save保存后部署该分支即可获得300s超时上限。

不过，玩玩沉浸式翻译，把每次请求最大文本长度调小一点不超时的话，还是不错的。 (自定义域名的情况下)

Vercel的并发大概有==50-60QPS==。即使是中小段落翻译任务，并发依然稳在==30QPS==

并发测试水平:

短对话:

{"role": "user", "content": content: "Say this is a test!"}

日常翻译:

[{"role": "system", "content": "你是一个专业,地道的翻译引擎，你只返回译文，不含任何解释"},
{"role": "user", "content": "将下面 YAML 格式的文本中的 text 字段翻译为 Simplified Chinese Language，并将翻译结果写在 text 字段中\n\nExample request:\n  - id: 1\n    text: Source\nExample result:\n  - id: 1\n    text: Translation\n\n开始翻译:\n\n- id: 1\n  text: The Philippines' official vessels infringed on China's rights, made provocations in the disguise of fishery protection, and organized media to hype up misinformation, which undermined stability in the South China Sea, he noted.\n- id: 2\n  text: Any tactic infringing on China's rights is futile, he warned.\n- id: 3\n  text: The CCG will carry out regular rights protection and law enforcement operations in waters under China's jurisdiction, and resolutely safeguard the country's territorial sovereignty and maritime rights and interests, he said."}]

Request Example

You don't have to pass Authorization, of course, you can also pass any string randomly.

curl http://127.0.0.1:3040/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer any_string_you_like" \
  -d '{
    "model": "gpt-3.5-turbo",
    "messages": [
      {
        "role": "user",
        "content": "Hello!"
      }
    ],
    "stream": true
    }'

Compatibility

You can use it in any app, such as OpenCat, Next-Chat, Lobe-Chat, Bob, etc. Feel free to fill in an API Key with any string, for example, gptyyds.
