Describe the Bug

when I use model gpt-4，it always not work！

[hello@xxx temp]# npx chatgpt@latest --model gpt-4 "what is your GPT version?what time do your knowledge cutoff?"
 I am based on GPT-3, which is the latest version as of my knowledge cutoff in September 2021. 

And the bill at openAI console haved pay for gpt-4。It is so weird ， until see the code
chatgpt-api.ts#L83

if (this._systemMessage === undefined) {
      const currentDate = new Date().toISOString().split('T')[0]
      this._systemMessage = `You are ChatGPT, a large language model trained by OpenAI. Answer as concisely as possible.\nKnowledge cutoff: 2021-09-01\nCurrent date: ${currentDate}`
    }

Looks like this is not issue with this library but rather OpenAI disabled gpt4.

Probably the issue should be closed.

the default systemMessage shoud not include “Knowledge cutoff: 2021-09-01”，this will make the chatgpt answer “I am based on GPT-3”。
chatgpt-api.ts#L83

Probably the issue should be closed.

[transitive-bullshit]

This project is undergoing a major revamp; closing out old issues as part of the prep process.

The chatgpt package is pretty outdated at this point. I recommend that you use the openai package or the openai-fetch package instead.
