🚀 Unlock the Power of AI in Your Python Projects Without Breaking the Bank! 🚀

Working with the OpenAI API can supercharge your Python applications, but costs can add up quickly if you're not careful. In this easy-to-follow guide, we'll share top tips to help you save money and keep your API key secure—all while getting amazing results!

1. Keep Your API Calls in Check​

Every time your app talks to OpenAI, it costs money. So, it's important to limit unnecessary requests.

🛡️ Example: Control User Requests​

If your app lets users make requests, set a limit to prevent too many calls.

import openai
from time import sleep

# Simple rate-limiting function
def rate_limit(api_calls, max_requests=5, time_limit=60):
    if api_calls >= max_requests:
        print(f"Max API calls reached. Waiting for {time_limit} seconds...")
        sleep(time_limit)
    return api_calls + 1

# Track API requests
api_calls = 0
api_calls = rate_limit(api_calls)

💡 Tip: Shorter Responses Save Money​

Use max_tokens wisely. Short answers cost less!

response = openai.Completion.create(
  model="gpt-4o-mini",  # Cost-effective model
  prompt="Explain recursion in programming.",
  max_tokens=50  # Keep it short to save tokens
)
print(response.choices[0].text)

2. Choose the Right AI Model​

Not all OpenAI models are the same. Some are pricier but not always necessary.

🤖 Example: Use GPT-4o Mini for Savings​

The GPT-4o mini model is smart and cheaper. Perfect for most tasks!

ModelInput Token CostOutput Token Cost
GPT-4o mini$0.075 per 1M tokens$0.300 per 1M tokens
GPT-4o$0.150 per 1M tokens$0.600 per 1M tokens
response = openai.Completion.create(
  model="gpt-4o-mini",
  prompt="What's machine learning?",
  max_tokens=100  # Control costs by adjusting
)
print(response.choices[0].text)

3. Set Spending Limits and Watch Your Costs​

Avoid surprise bills by setting spending limits.

💳 Example: Set a Monthly Budget​

  1. Log in to your OpenAI account.
  2. Go to Billing & Usage.
  3. Set a hard limit on your monthly spend.

This keeps your costs in check, even if something goes wrong in your app.

4. Protect Your API Key​

Your API key is like a password. Keep it safe!

🔒 How to Secure Your API Key​

  • Don't hardcode it in your code. Use environment variables instead.
  • Use a secrets manager like AWS Secrets Manager or GitHub Secrets for cloud deployments.
import os

# Securely load your API key
openai.api_key = os.getenv("OPENAI_API_KEY")

If someone steals your key, they could run up your costs. Treat it with care!

5. Keep an Eye on Token Usage​

Monitor how many tokens you use to stay within budget.

response = openai.Completion.create(
  model="gpt-4o-mini",
  prompt="What is natural language processing?",
  max_tokens=100
)

print(f"Total Tokens Used: {response['usage']['total_tokens']}")

Tracking tokens helps you see where you can save more.
