I have just started experiemnnting with OpenAI API as well as LangChain. I get the error of You exceeded your current quota, please check your plan and billing details.

Here is my simple code

`
!pip install openai
!pip install --upgrade langchain

import openai
import os
import langchain

openai_api_key='MY_KEY'

from langchain.chat_models import ChatOpenAI
from langchain.schema import HumanMessage, SystemMessage, AIMessage

chat = ChatOpenAI(temperature=.7, openai_api_key=openai_api_key, request_timeout=120)

chat(

 [

  SystemMessage(content="You are a nice AI bot that helps a human to figure out what to eat in one short sentence"),  
  HumanMessage(content="I like tomatoes, what should I eat")
  
 ]

)

`

That is all. I get the error of Rate limit. Its the first time i am using LangChain
