Stream nor ChatCompletionStream types not exported

[edgar0011]

Confirm this is a Node library issue and not an underlying OpenAI API issue

• [X] This is an issue with the Node library

Describe the bug

One of openai.chat.completions.create return types is ApiPromise<Stream<OpenAI.Chat.ChatCompletionChunk>> yet the Stream is not the intrinsic Nodejs Stream, and not exported from openai.

To Reproduce

try to set type of awaited or in Promise return value from openai.chat.completions.create()

Code snippets

import OpenAI from 'openai'

import { config } from 'server/config'
import { errorHandler } from 'server/helpers'

const openai = new OpenAI({
  apiKey: config?.OPENAI_API_KEY as string,
})

export const createText = async(prompt: string): Promise<OpenAI.Chat.ChatCompletion | null> => {
  try {
    const params: OpenAI.Chat.ChatCompletionCreateParams = {
      messages: [{ role: 'user', content: prompt }],
      model: 'gpt-3.5-turbo',
      stream: true,
    }

    const options: OpenAI.RequestOptions = {}

    const chatCompletion: OpenAI.Stream<OpenAI.Chat.ChatCompletionChunk> = await openai.chat.completions.create(params, options)

    return chatCompletion
  } catch (error: unknown) {
    console.error(error)
    errorHandler(error)
    return null
  }
}

Right now you can

import { Stream } from 'openai/streaming';
import { ChatCompletionStream } from 'openai/lib/ChatCompletionStream';

We'll take a look at adding them to the top-level export.

This is actually good, IMO, but is this documented?

Thanks! We do need better docs on this. What would you like to see in those docs?
