Lab 3 : 使用 OpenAI API 呼叫ChatGPT進行對談

doc: https://platform.openai.com/docs/api-reference/chat

POST /v1/chat/completions HTTP/1.1
Host: api.openai.com
Authorization: Bearer [replace_key]
Content-Type: application/json
Content-Length: 138

{
  "model": "gpt-3.5-turbo",
  "max_tokens" : 300, 
  "temperature" : 0.1, 
  "messages": 
  [
      {"role": "user", "content": "今天外面天氣很好耶~你覺得我們該做些什麼?"}
  ]
}

👉試試看 詢問 "最南端的城市是哪一個呢?" 結果是? 👉改加入歷史訊息

{
  "model": "gpt-3.5-turbo",
  "max_tokens" : 300, 
  "temperature" : 0.1, 
  "messages": 
  [
      {"role": "user", "content": "台灣最大的城市是哪一個?"},
      {"role": "assistant", "content": "台灣最大的城市是台北市。"},
      {"role": "user", "content": "那最南端的城市是哪一個呢?"}
  ]
}

🙋‍♀️ 如果只問 "最南端的城市是哪一個呢?"，不透過歷史訊息，也不改問題。還可以改什麼部分讓AI回答的答案是正確的? image
