Using the OpenAI API with Python is a powerful way to incorporate state-of-the-art natural language processing capabilities into your applications. This blog post provides a step-by-step walk through for creating an OpenAPI account, obtaining an API key, and creating a program to perform queries using the OpenAI API. Additionally, an example demonstrating how to create a podman image to run the code on Kubernetes is provided.

Creating an OpenAI Account and API Key

Before building the code, create an OpenAI account and obtain an API key. Follow these steps:

1. Go to the OpenAI website.
2. Click on the “Sign up for free” button in the top right corner of the page.
3. Fill out the registration form and click “Create Account”.
4. Once an account has been created, go to the OpenAI API page.
5. Click on the “Get API Key” button.
6. Follow the prompts to obtain a API key.

Installing Required Packages

To use the OpenAI API with Python, install the OpenAI package. Open a command prompt or terminal and run the following command:

pip install openai

Using the OpenAI API with Python

With the OpenAI account and API key, as well as the required packages installed, write a simple Python program. In this example, create a program that generates a list of 10 potential article titles based on a given prompt.

First, let’s import the OpenAI package and set our API key:

import openai
openai.api_key = "YOUR_API_KEY_HERE"

Next, define the prompt:

prompt = "10 potential article titles based on a given prompt"

Now use the OpenAI API to generate the list of article titles:

response = openai.Completion.create(
    engine="text-davinci-002",
    prompt=prompt,
    max_tokens=50,
    n=10,
    stop=None,
    temperature=0.5,
)
titles = [choice.text for choice in response.choices]

Let’s break this down:

• engine="text-davinci-002" specifies which OpenAI model to use. This example uses the “Davinci” model, which is the most capable and general-purpose model currently available.
• prompt=prompt sets the prompt to our defined variable.
• max_tokens=50 limits the number of tokens (words) in each generated title to 50.
• n=10 specifies that we want to generate 10 potential article titles.
• stop=None specifies that we don’t want to include any stop sequences that would cause the generated text to end prematurely.
• temperature=0.5 controls the randomness of the generated text. A lower temperature will result in more conservative and predictable output, while a higher temperature will result in more diverse and surprising output.

The response variable contains the API response, which includes a list of choices. Each choice represents a generated title. This will extract the generated titles from the choices list and store them in a separate titles list.

Finally, print out the generated titles:

for i, title in enumerate(titles):
    print(f"{i+1}. {title}")

This will output something like:

1. 10 Potential Article Titles Based on a Given Prompt
2. The Top 10 Articles You Should Read Based on This Prompt
3. How to Come Up with 10 Potential Article Titles in Minutes
4. The Ultimate List of 10 Article Titles Based on Any Prompt
5. 10 Articles That Will Change Your Perspective on This Topic
6. How to Use This Prompt to Write 10 Articles Your Audience Will Love
7. 10 Headlines That Will Instantly Hook Your Readers
8. The 10 Most Compelling Article Titles You Can Write Based on This Prompt
9. 10 Article Titles That Will Make You Stand Out from the Crowd
10. The 10 Best Article Titles You Can Write Based on This Prompt

And that’s it! You’ve successfully used the OpenAI API to generate a list of potential article titles based on a given prompt.

Creating a Podman Image to Run on Kubernetes

To run the program on Kubernetes, create a podman image containing the necessary dependencies and the Python program. Here are the steps to create the image:

1. Create a new file called Dockerfile in a working directory.
2. Add the following code to the Dockerfile:

FROM python:3.8-slim-buster
RUN pip install openai
WORKDIR /app
COPY your_program.py .
CMD ["python", "your_program.py"]

This file tells Docker to use the official Python 3.8 image as the base, install the openai package, set the working directory to /app, copy your Python program into the container, and run the program when the container starts.

To build the image:

1. Open a terminal or command prompt and navigate to a working directory.
2. Build the image by running the following command:

podman build -t your_image_name . 

Replace “image_name” with the name for the image.

To run the image:

podman run image_name

This will start a new container using the image created and subsequently run the program created above.

Verify the image runs and spits out what the desired output. Run it on a Kubernetes cluster as a simple pod. There are two ways to accomplish this in Kubernetes, declaratively or imperatively.

Imperative

The imperative way is quite simple:

kubectl run my-pod --image=my-image

This command will create a pod with the name “my-pod" and the image “my-image".

Declarative

The declarative way of creating a Kubernetes pod involves creating a YAML file that describes the desired state of the pod and using the kubectl apply command to apply the configuration to the cluster.

apiVersion: v1
kind: Pod
metadata:
  name: my-pod
spec:
  containers:
    - name: my-container
      image: my-image

Save it as “my-pod.yaml”

Outside of automation running this on the Kubernetes cluster from the command line can be accomplished with:

kubectl apply -f my-pod.yaml

This command will create a pod with the name “my-pod" and the image “my-image". The -f option specifies the path to the YAML file containing the pod configuration.

Obviously this is quite simple and there’s plenty of ways to accomplish running this code in Kubernetes as a deployment or replicaset or some other method.

Congratulations! Using the OpenAI API with Python and creating a podman image to run a program on Kubernetes is quite straightforward. With these tools available. Incorporating the power of natural language processing into your applications is both straightforward and very powerful.
