ChatGPT是目前最先進的AI聊天機器人，它能夠理解圖片和文字，生成流暢和有趣的回答。如果你想跟上AI時代的潮流，你一定要學會使用ChatGPT。如果你想了解OpenAI最新發布的GPT-4模型，以及它如何為ChatGPT聊天機器人帶來更強大的功能，那麼你一定不要錯過OpenAI官網推薦的48種最佳應用場景，不管你是資深開發者、初學者，你都能夠從0到1快速入門，並掌握他們。
在這個AI大時代，如果不想被人顛覆，就要先顛覆別人。如果你顛覆不了別人，那你就努力運用ChatGPT提高你的技術水平和創造力。
ChatGPT能根據使用者需求，扮演各種角色與你聊天，甚至根據使用者需求，它也可以成為一個幽默、有趣的機器人，根據不同的情況提出有趣的見解或者諷刺語句，幫助你在無聊的時候得到更多的樂趣。ChatGPT這種良好的互動性，可以更好地滿足使用者的需求，進行更加友好高效的交流。
Introduce 簡介
Marv the sarcastic chat bot 諷刺聊天機器人Marv
Marv is a factual chatbot that is also sarcastic.
Marv是一個事實聊天機器人，也是諷刺。
setting 設定
Engine： text-davinci-003
Max tokens：60
Temperature：0.5
Top p：0.3
Frequency penalty：0.5
Presence penalty：0.0
說明：
0、Engine設定定義了你要使用的模型，例如 text-davinci-003是一個文字生成模型。這種模型可以根據輸入的文字，生成新的、相關的文字。
1、Max tokens是指在請求中最多允許返回的 token 數目，比如你可以指定 chatGPT 返回最多60個 token。這可以幫助你控制輸出的內容大小，以便更好地控制響應速度和結果。一般1個token約4個字元或者0.75個單詞
2、Temperature是一個引數，用於控制 chatGPT 的輸出。它決定了 chatGPT 在生成文字時會多麼“隨意”。值越高，chatGPT 生成的文字就越不可預測；值越低，chatGPT 生成的文字就越可預測。它在0.0到2.0之間，Temperature設定為0意味著ChatGPT將會生成更加保守的回覆，即更少的隨機性和更多的準確性，這可以幫助你在聊天中更好地控制語義，並且可以防止ChatGPT產生不相關的內容。通常建議更改此值或Top P，但不要同時更改這兩個值。
3、Top p是隨溫度取樣的替代方案，稱為核取樣，其中模型考慮具有top_p機率質量的標記的結果。因此0.1意味著僅考慮包括前10%機率質量的記號。通常建議更改此值或temperature，但不要同時更改這兩個值。
4、Frequency penalty是指在訓練時，模型會根據詞頻來調整每個單詞的重要性。它可以幫助模型更好地理解文字，並減少過擬合。介於-2.0和2.0之間的數字。正值會根據新標記在文字中的現有頻率懲罰新標記，從而降低模型逐字重複同一行的可能性。Frequency penalty設定為0意味著模型不會對重複的詞進行懲罰。它可以幫助模型生成更多的新詞，而不是重複使用已有的詞。
5、Presence penalty是指在ChatGPT中，一些預先定義的條件或者狀態可能會影響機器人回答的質量，介於-2.0和2.0之間的數字。正值會根據新標記到目前為止是否出現在文字中來懲罰它們，從而增加模型談論新主題的可能性。如果將 Presence penalty 設定為 0，則表示不會有任何懲罰。
