OpenAI API 持续对话中的交互式对话

Question

OpenAI API 持续对话中的交互式对话

54

我正在尝试使用openAI API并尝试继续一次对话。例如：

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)

这将按以下格式生成一个俳句：

{
  "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
  }
}

这很棒。但是，如果我现在想要询问“再写一个给我怎么办”呢？如果我使用openAI playground chat或chatGPT，我可以继续对话。我想通过我的Python脚本来实现这一点。我注意到我会收到一个响应中的id。我能用这个id来继续我的对话吗？

很棒的帖子，附带说一句：付费API没有一个你可以通过使用OpenAI账户免费获得的功能是相当愚蠢的，并且依赖于可能会产生更高成本的自制hack。这是一种不道德的支持自己开发者社区的方法。 - InfiniteStack

我为此编写了一个名为ai-chat-chain的Python库，它比专注于不同事物的LangChain更易于使用（对我来说）。 - Erik Aronesty

实际上，你可以做任何想做的事情，很简单。只需提供前一次对话的输入部分给 OpenAI。

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

不要忘记在“openai.Completion.create”中设置“stop”变量。

stop=["\n"]

在这里，“\n”将作为消息之间的分隔符。

以大量代币/金钱的代价重新发送庞大的聊天记录积压，我可以看出这比添加正确的支持会话 ID 字段对 OpenAI 更方便。 - Asiel Diaz Benitez

维护会话ID要复杂得多，因为服务器端必须保留所有会话数据，这对于OpenAI级别的API调用来说将是一项巨大的任务。现在做这件事情的工程更简单，尽管当然会收取更高的费用。但实际上，API的价格完全由OpenAI决定，如果他们想要更多，他们可以收取更高的费用。 - Edward Luo

实际上，费用与模型需要处理的上下文数量有关。 "会话维护"与成本关系不大，但会带来一些便利...... 但他们仍然必须为会话大小收费！如果你不需要上下文，那么这反而会增加成本。 - Erik Aronesty

修改Stan Chan的代码，以处理可能发送的最大对话数量，使用相同的输入重复相同的答案，捕获速率限制错误，并更新新信息，例如当前时间和日期。

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

结果：

更新:

我找到的最佳解决方案是使用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)

我尝试了一个非常昂贵的想法，似乎有效。这个想法是通过在当前提示中丰富以前的提示和响应来提供以前讨论的上下文。请看下面的示例代码。

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])

以下是我从API中收到的聊天示例。

- Samuel Nde

是的，这就是我现在正在做的事情，而且（费用）正是我提出这个问题的原因哈哈。我确实相信，按照他们目前的设置，这是“正确”的做法。 - Cfomodz

响应中的ID用于标识响应所针对的特定查询。根据您在请求主体中提供的身份建议，user字段是OpenAI用于监视和检测滥用行为的，如其文档中所述。

如果您想生成不同的结果，可以增加请求中的temperature字段然后再运行它。其中一些工作需要考虑您如何设计提示。更多信息，请参阅OpenAI 文档。

好的，谢谢。希望很快会有一个chatGPT API可以维持对话。 - Charmalade

OpenAI现在正式发布了"gpt-3.5-turbo"模型。这里有一些示例代码：https://github.com/stancsz/chatgpt 还有官方文档。

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"]
