Chaining Prompts

Prompt Chaining is a technique of connecting multiple tasks to generate complex content by breaking down a large generative task into smaller, more manageable pieces.

Examples of prompt chaining are generating product descriptions, creating personalized email campaigns, and generating complex chatbot responses.

Setup

Python

import json
import os
import openai
from dotenv import load_dotenv, find_dotenv
_ = load_dotenv(find_dotenv()) 

openai.api_key = os.environ['OPENAI_API_KEY']

Helper function

def get_completion_from_messages(messages,
                                 model="gpt-3.5-turbo",
                                 temperature=0,
                                 max_tokens=500):
    response = openai.ChatCompletion.create(
        model=model,
        messages=messages,
        temperature=temperature,
        max_tokens=max_tokens,
    )
    return response.choices[0].message["content"]
