openai-api - NodeJS 中的 OpenAI API : How do I migrate from text-davinci-003 to gpt-3. 5-turbo？

Question

如何从 text-davinci-003 迁移到 gpt-3.5-turbo？

我尝试做的事情如下:

改变这个...

model: "text-davinci-003"

...对此。

model: "gpt-3.5-turbo"

此外，更改此...

const API_URL = "https://api.openai.com/v1/completions";

...对此。

const API_URL = "https://api.openai.com/v1/chat/completions";

问题是它不起作用。我将给出的代码是未修改的代码，以便任何人都可以帮助我更改哪些内容。

为什么我想要这次升级？text-davinci-003 的完成让我很恼火。就像发送“Hello”会给我一封完整的信而不是问候语。

您使用的是 gpt-3.5-turbo 型号。

Chat Completions API 之间存在三个主要区别(即 GPT-3.5 API)和 Completions API (即 GPT-3 API)。

1. API端点
   • Completions API:https://api.openai.com/v1/completions
   • 聊天完成 API:https://api.openai.com/v1/chat/completions
2. prompt 参数(Completions API)已替换为 messages 参数(Chat Completions API)
3. 响应访问
   • 完成 API:response.choices[0].text.trim()
   • 聊天完成 API:response.choices[0].message.content.trim()

试试这个:

const getChatResponse = async (incomingChatDiv) => {
    const API_URL = "https://api.openai.com/v1/chat/completions"; /* Changed */
    const pElement = document.createElement("p");

    // Define the properties and data for the API request
    const requestOptions = {
        method: "POST",
        headers: {
            "Content-Type": "application/json",
            "Authorization": `Bearer ${API_KEY}`
        },
        body: JSON.stringify({
            model: "gpt-3.5-turbo",
            messages: [{role: "user", content: `${userText}`}], /* Changed */
            max_tokens: 2048,
            temperature: 0.2,
            n: 1,
            stop: null
        })
    }

    // Send POST request to API, get response and set the reponse as paragraph element text
    try {
        const response = await (await fetch(API_URL, requestOptions)).json();
        pElement.textContent = response.choices[0].message.content.trim(); /* Changed */
    } catch (error) { // Add error class to the paragraph element and set error text
        pElement.classList.add("error");
        pElement.textContent = "Oops! Something went wrong while retrieving the response. Please try again.";
    }

    // Remove the typing animation, append the paragraph element and save the chats to local storage
    incomingChatDiv.querySelector(".typing-animation").remove();
    incomingChatDiv.querySelector(".chat-details").appendChild(pElement);
    localStorage.setItem("all-chats-thedoggybrad", chatContainer.innerHTML);
    chatContainer.scrollTo(0, chatContainer.scrollHeight);
}
