OpenAI API continuing conversation in a dialogue

Question

I am playing around with the openAI API and I am trying to continue a conversation. For example:

import openai
openai.api_key = mykey
    
prompt= "write me a haiku"
    
response = openai.Completion.create(engine="text-davinci-001",
                                    prompt=prompt,
                                    max_tokens=50)
print(response)

This produces a Haiku in the following format:

{
  "choices": [
    {
      "finish_reason": "stop",
      "index": 0,
      "logprobs": null,
      "text": "\n\n\n\nThis world is\nfull of wonders\nSo much to see and do"
    }
  ],
  "created": 1670379922,
  "id": "cmpl-6KePalYQFhm1cXmwOOJdyKiygSMUq",
  "model": "text-davinci-001",
  "object": "text_completion",
  "usage": {
    "completion_tokens": 17,
    "prompt_tokens": 5,
    "total_tokens": 22
  }
}

Which is great. However, what if I now want to ask to "write me another"? If I use the the openAI playground chat or chatGPT, I am able to continue the conversation. I would like to do this via my python script. I notice I receive an id in response. Can I use this somehow to continue my conversation?

Great post, sidenote: It's quite dumb for paid API not to have a feature you can get for free using an OpenAI account, and rely on self-made hacks that can potentially cost even more. Unethical approach to supporting your own dev community. – Lop

i wrote a python library for this called ai-chat-chain, it's easier to use (for me) than langchain which is focused on different things – Endogamy

OpenAI Now officially released the "gpt-3.5-turbo" model. Here's some sample code:https://github.com/stancsz/chatgpt

and here's the official docs.

import os
import openai


class ChatApp:
    def __init__(self):
        # Setting the API key to use the OpenAI API
        openai.api_key = os.getenv("OPENAI_API_KEY")
        self.messages = [
            {"role": "system", "content": "You are a coding tutor bot to help user write and optimize python code."},
        ]

    def chat(self, message):
        self.messages.append({"role": "user", "content": message})
        response = openai.ChatCompletion.create(
            model="gpt-3.5-turbo",
            messages=self.messages
        )
        self.messages.append({"role": "assistant", "content": response["choices"][0]["message"].content})
        return response["choices"][0]["message"]

stop=["\n"] the stop sequence is a bit more complicated. I'd suggest not using it altogether for now. community.openai.com/t/… – Andy

Thanks for the great code. I just don't know if adding previous messages to new requests adds to the cost that's calculated based on (input + output tokens) each time! This can also affect the number of generated tokens, right? Since we have a limit of 2048 when using "gpt-3.5-turbo" – Schnitzel

I have updated and modified it to fulfil issues like an endless dialogue that can be expensive, using deque and list, caching same input and updating information at time of chat https://mcmap.net/q/325075/-openai-api-continuing-conversation-in-a-dialogue – Akilahakili

This is the same as @Special1st's answer - ie. still managing the context yourself and sending it anew on each message. – Dominant

Congrats. Your coding skills just passed the turning test... – Lop

how to run this? – Loquacious

Answer 2

In fact you can do what you want, it's simple. Just provide to openai inputs part of previous conversation.

prompt = "chat message 1\n" + "chat message2\n" + ... + "your last message\n"

And don't forget to set up "stop" variable in "openai.Completion.create".

stop=["\n"]

Here "\n" will be used as delimiter between messages.

Ornithomancy

at the cost of a lot more tokens/money re-sending substantial backlog of the chat... I can see how this is more convenient to OpenAI than adding proper support for a session id field... – Predominant

Maintaining a session id is much more complicated since the server side has to keep all the session data, it will be an enormous task for OpenAI level of api callings. It's engineering simpler to do it now, though of course it charges more. But indeed the price of API is completely dictated by OpenAI, they could just charge more if they wanted more. – Adamite

actually, the expense has to do with how much context the model has to process. "session maintenance" has little to do with the cost, and would be a nice convenience..... but they would still have to charge you for the session size! if anything that would increase costs if you don't need the context – Endogamy

It’s crazy to me that OpenAI does not support this. Passing the entire conversation each time makes the cost grow exponentially. To say nothing of the fact that the endpoint is called “chat” when in reality it only supports a single message. – Calysta

Answer 3

Modifying Stan Chan's code to handle a maximum number of dialogues that could be sent, repeat the same answer with the same input, catch rate limit error and also update new information, e.g. the current time and date.

from os import environ
from collections import deque
from datetime import datetime
from functools import lru_cache

import openai



# Inspired by Stan Chen's code: https://github.com/stancsz/chatgpt
environ["OPENAI_API_KEY"] = "KEYS FROM SOMEWHERE .env"
CHAT_MODEL = "gpt-3.5-turbo"
PROMPT = """Your name is Kim. A kind and friendly AI assistant that answers in \
    a short and concise answer. Give short step-by-step reasoning if required."""


class Chat:
    def __init__(self, converstion_limit: int = 8):

        # number of chats to remember
        self.messages_queue = deque(maxlen=converstion_limit)

    @lru_cache(maxsize=518)
    def chat(self, message: str) -> str:
        self.messages_queue.append({"role": "user", "content": message})

        try:
            prompty = {
                "role": "user",
                "content": f"{PROMPT} Today is {datetime.now(): %A %d %B %Y %H:%M}",
            }
            response = openai.ChatCompletion.create(
                model=CHAT_MODEL, messages=[prompty, *self.messages_queue]
            )

            reply = response["choices"][0]["message"].content

            self.messages_queue.append({"role": "assistant", "content": reply})
        except openai.error.RateLimitError:
            reply = "I am currently overloaded with other requests."

        return reply

Results:

Update:

The best solution I found is to use langchain

from os import environ
from langchain.chains.conversation.memory import ConversationBufferMemory
from langchain import OpenAI, LLMChain, PromptTemplate

environ["OPENAI_API_KEY"] = "KEYS FROM SOMEWHERE .env"
template = """You are a mathematician. Given the text of question, it is your job to write an answer that question with example.
{chat_history}
Human: {question}
AI:
"""
prompt_template = PromptTemplate(input_variables=["chat_history","question"], template=template)
memory = ConversationBufferMemory(memory_key="chat_history")

llm_chain = LLMChain(
    llm=OpenAI(),
    prompt=prompt_template,
    verbose=True,
    memory=memory,
)

llm_chain.run("What is 4 + 3?")

result = llm_chain.run("add 7 to it")
print(result)

Answer 4

I tried a VERY EXPENSIVE IDEA and it seemed to work. The idea is to provide the context of previous discussions by enriching your current prompt with the previous promts and responses.

See my sample code below.

`

import re, requests, os
env = os.environ
OPENAI_PUBLIC_KEY = env['OPENAI_PUBLIC_KEY']

public_end_point = 'https://api.openai.com/v1/completions'
headers = {'authorization': f"Bearer {OPENAI_PUBLIC_KEY}"}

#This function provides the context. Note that that it will consume a lot of tokens (input tokens)
def get_last_5_summary_chats(chats):
    res =''
    for index, question_response in enumerate(chats[-5:]):
        res+= f"prompt{index}: {question_response[0]} response{index}: {question_response[1]} "
    if(len(chats)> 3):
        res = "Give short responses only. "+ res
    return res

#Store your chat history in session_chats
session_chats = []

#Set Input Parameters to the endpoint
data = { "model": 'text-davinci-003', "max_tokens": 400, "temperature": 1, "top_p": 0.6}

for ind in range(10):
    prev_context = get_last_5_summary_chats(session_chats)
    prompt = input("Ask your question:\t").strip()
    data['prompt'] = f"{prev_context} {prompt}".strip()
    r = requests.post(public_end_point, headers=headers, json=data)
    public_response = r.json()
    response_text = public_response['choices'][0]['text'].strip()
    print(f"QUESTION:\t{prompt}\n")
    print(f"RESPONSE:\t {response_text}\n\n")
    session_chats.append([prompt, response_text])

`

See a sample chat I had from api below.

Yeah, this is what I am doing right now and that (the expense) is the reason I am coming to this question haha. I do believe as they have it set up right now this is the "correct" way to do this. – Ken

Every N iterations, you can ask it to summarize the whole conversation so far in a very succinct way, which would produce a 'compressed chat'. In the next N iterations you would use only that_summary + new_additions. I have seen that idea in action in github.com/ProfSynapse/Synapse_CoR (see "/save" command). – Cesium

Answer 5

The ID in the response is used to identify the particular query that the response is for. The user field as per your identity suggestion in the request body is specifically used by OpenAI to monitor and detect abuse, as outlined in their documentation.

If you want to generate a different result, you can increase the temperature field in the request and simply run it again. Some of the work needs to go to how you engineered your prompts. For more information, please refer to the OpenAI documentation.OpenAI Documentation

Ah ok, thanks. Hopefully there is a chatGPT API soon that can maintain a conversation. – Superabound

concatenating the past questions and answers on the new request will allow to maintain a conversation. Check this answer: https://mcmap.net/q/325075/-openai-api-continuing-conversation-in-a-dialogue – Lavone

Answer 6

Here is a bit more elaborate version of the above Code...

• Keeps History in file, so it can be resumed.
• uses audio input (and TODO audio ouput)
• Triggers the bot into a specific different persona than standartmodel by using a trigger-prompt
