gpt-35-turbo не запоминает сообщения в PHP

Question

Я создал бота Telegram, который отвечает на сообщения пользователей, используя API OpenAI GPT. Все работает нормально, но есть проблема. В модели gpt-35-turbo есть возможность добавлять параметры для запоминания сообщений и отслеживания разговоров, что я и сделал, но не работает. Я делюсь своим кодом для помощи

Вот мой код

      <?php

class Bot
{
    private $bot_token;

    public function __construct($bot_token)
    {
        $this->bot_token = $bot_token;
    }

    public function handleUpdate($update)
    {
        $message = $update['message'];
        $chat_id = $message['chat']['id'];
        $text = $message['text'];

        switch ($text) {
            case '/start':
                $this->sendTypingAction($chat_id);
                sleep(1);
                $welcome_message = " Hello \nWith me, you can get the answer to EVERYTHING in a few seconds!\n\n    I speak all languages, send /prof to start";
                $this->sendMessage($chat_id, $welcome_message);
                break;
            case '/help':
                $this->sendTypingAction($chat_id);
                sleep(1);
                $help_message = "Need help? Here's what I can do: \n\n/start - To begin\n/help - To get help\n/prof - To start a chat session with a virtual teacher";
                $this->sendMessage($chat_id, $help_message);
                break;
            default:
                $this->sendTypingAction($chat_id);
                sleep(1);
                $response = $this->generateResponse($text);
