Using OpenAI API with PowerShell

Introduction

This tutorial demonstrates how to integrate and use the OpenAI API with PowerShell to leverage advanced AI capabilities in your scripts.

1. Setting Up Your OpenAI API Key

Before starting, make sure you have your OpenAI API key ready. You can obtain it from the OpenAI website after signing up for an account.

2. Installing Necessary Tools

To use the OpenAI API in your PowerShell scripts, you will need to have `Invoke-RestMethod` available, which is built into PowerShell. Ensure your PowerShell version is up-to-date to avoid compatibility issues.

3. Making API Requests

To make requests to the OpenAI API using PowerShell, you'll use the `Invoke-RestMethod` command to send HTTP requests.

Text Completion

Here’s an example of making a request for text completion:

# PowerShell Script for Text Completion using OpenAI API

$apiKey = "YOUR_API_KEY_HERE"
$prompt = "Translate English to French: Hello, how are you?"
$model = "text-davinci-003"
$maxTokens = 50

$response = Invoke-RestMethod -Uri "https://api.openai.com/v1/completions" -Method Post -Headers @{
    "Content-Type" = "application/json"
    "Authorization" = "Bearer $apiKey"
} -Body (ConvertTo-Json @{
    model = $model
    prompt = $prompt
    max_tokens = $maxTokens
})

$response.choices.text
                    

This PowerShell script sends a POST request to the OpenAI API for text completion and prints the API response.

Code Generation

Here’s an example of making a request for code generation:

# PowerShell Script for Code Generation using OpenAI API

$apiKey = "YOUR_API_KEY_HERE"
$prompt = "Generate Python code to sort an array using bubble sort"
$model = "davinci-codex"
$maxTokens = 150

$response = Invoke-RestMethod -Uri "https://api.openai.com/v1/engines/$model/completions" -Method Post -Headers @{
    "Content-Type" = "application/json"
    "Authorization" = "Bearer $apiKey"
} -Body (ConvertTo-Json @{
    prompt = $prompt
    max_tokens = $maxTokens
    stop = @("\n")
})

$response.choices.text
                    

def bubble_sort(arr):
    n = len(arr)
    for i in range(n):
        for j in range(0, n-i-1):
            if arr[j] > arr[j+1]:
                arr[j], arr[j+1] = arr[j+1], arr[j]
    return arr
                        

This PowerShell script sends a POST request to the OpenAI Codex engine for code generation and prints the generated code.

4. Handling Responses

Once you receive a response from the API, you can handle it in your PowerShell script.

Text Completion

Here’s how you might handle the completion response:

# PowerShell Script to Handle Text Completion Response

$response = Invoke-RestMethod -Uri "https://api.openai.com/v1/completions" -Method Post -Headers @{
    "Content-Type" = "application/json"
    "Authorization" = "Bearer $apiKey"
} -Body (ConvertTo-Json @{
    model = $model
    prompt = $prompt
    max_tokens = $maxTokens
})

$translatedText = $response.choices.text
Write-Output "Translated Text: $translatedText"
                    

In this example, `$response` contains the JSON response from the OpenAI API, and `Write-Output` is used to print the translated text.

Code Generation

Here’s how you might handle the code generation response:

# PowerShell Script to Handle Code Generation Response

$response = Invoke-RestMethod -Uri "https://api.openai.com/v1/engines/$model/completions" -Method Post -Headers @{
    "Content-Type" = "application/json"
    "Authorization" = "Bearer $apiKey"
} -Body (ConvertTo-Json @{
    prompt = $prompt
    max_tokens = $maxTokens
    stop = @("\n")
})

$generatedCode = $response.choices.text
Write-Output "Generated Code: $generatedCode"
                    

In this example, `$response` contains the JSON response from the OpenAI API with the generated code, and `Write-Output` is used to print the code.
