Module 6: Hands-on with OpenAI API

In this hands-on module, we’ll apply the concepts you’ve learned to build and test real prompts using OpenAI’s ChatCompletion API (via the new OpenAI SDK openai>=1.0.0). We will also look at several mini-projects and explore how to integrate them into real-world applications.

Setup

!pip install --upgrade openai

from openai import OpenAI
import os

client = OpenAI(api_key=os.getenv("OPENAI_API_KEY"))

1. Simple ChatBot Interaction

response = client.chat.completions.create(
    model="gpt-3.5-turbo",
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Who won the FIFA World Cup in 2022?"}
    ]
)
print(response.choices[0].message.content)

2. Custom Assistant Role

response = client.chat.completions.create(
    model="gpt-3.5-turbo",
    messages=[
        {"role": "system", "content": "You are a strict English grammar teacher."},
        {"role": "user", "content": "Correct this: He don't like the cold."}
    ]
)
print(response.choices[0].message.content)

3. Explore Parameters

Play with:

temperature: creativity
top_p: nucleus sampling
max_tokens: response length
stop: cut-off patterns
n: number of completions

response = client.chat.completions.create(
    model="gpt-3.5-turbo",
    temperature=0.9,
    top_p=0.85,
    max_tokens=100,
    messages=[
        {"role": "user", "content": "Write a short story about a cat on Mars."}
    ]
)
print(response.choices[0].message.content)

4. Mini-Applications

a) Summarizer

def summarize_text(text):
    response = client.chat.completions.create(
        model="gpt-3.5-turbo",
        messages=[
            {"role": "system", "content": "Summarize the following text."},
            {"role": "user", "content": text}
        ]
    )
    return response.choices[0].message.content

b) Idea Generator

def generate_ideas(topic):
    response = client.chat.completions.create(
        model="gpt-3.5-turbo",
        messages=[
            {"role": "system", "content": "You are a creative idea generator."},
            {"role": "user", "content": f"Give 5 unique business ideas on {topic}."}
        ]
    )
    return response.choices[0].message.content

5. Further Exploration Ideas

Quiz Generator: Generate multiple-choice questions from topics
Recipe Recommender: Generate recipes from given ingredients
Persona Bot: Change assistant behavior (e.g. a Shakespearean poet)
Resume Optimizer: Improve resumes using targeted prompts
Story Continuation: Ask GPT to continue a paragraph
