GPT-3.5-turbo how to remember previous messages like Chat-GPT website

API
23

I developed this node.js script to save every GPT-4 request and response into a JSON file.

It then sends the file content as conversation history with each new prompt.

// Import required modules
const fs = require('fs');
const axios = require('axios');

// Your OpenAI API key
const apiKey = 'your-openai-api-key';

// Function to interact with OpenAI API
async function interactWithAI(userPrompt) {
    try {
        // Define the message data structure
        let messageData = { 'messages': [] };

        // If requests.json exists, read and parse the file
        if (fs.existsSync('requests.json')) {
            let raw = fs.readFileSync('requests.json');
            messageData = JSON.parse(raw);
        }

        // Format the conversation history and the new user request
        let systemMessage = "Conversation history:\n" + messageData['messages'].map(m => `${m.role} [${m.timestamp}]: ${m.content}`).join("\n");
        let userMessage = "New request: " + userPrompt;

        // Make a POST request to OpenAI's chat API
        let response = await axios({
            method: 'post',
            url: 'https://api.openai.com/v1/chat/completions',
            headers: { 'Authorization': `Bearer ${apiKey}`, 'Content-Type': 'application/json' },
            data: { 'model': 'gpt-4', 'messages': [ { "role": "system", "content": systemMessage }, { "role": "user", "content": userMessage } ] }
        });

        // Log the AI's response
        console.log(response.data['choices'][0]['message']['content']);

        // Get the current timestamp
        let timestamp = new Date().toISOString();

        // Add the new user request and the AI's response to the message history
        messageData['messages'].push({ "role": "user", "content": userPrompt, "timestamp": timestamp });
        messageData['messages'].push({ "role": "assistant", "content": response.data['choices'][0]['message']['content'], "timestamp": timestamp });

        // Write the updated message history to requests.json
        fs.writeFileSync('requests.json', JSON.stringify(messageData, null, 2));

        // Return the AI's response
        return response.data['choices'][0]['message']['content'];
    } catch (e) {
        // If an error occurred, log it to the console and return an error message
        console.error('An error occurred:', e);
        return 'An error occurred while interacting with the OpenAI API. Please check the console for more details.';
    }
}
