Step 1: Install laravel 9

In this step, we will install the laravel 9 application using the following composer command.

composer create-project laravel/laravel OpenAI-Example

Step 2: Install the OpenAI PHP Package

In this step, we will install the openai-php/client package using the following command. OpenAI PHP is a supercharged PHP API client that allows you to interact with the Open AI API.

Note: Requires PHP 8.1+

Step 4: Create Routes

In this step, we create routes in the web.php file.

routes/web.php

<?php

use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('welcome');
});

Auth::routes();

Route::get('/home', [App\Http\Controllers\HomeController::class, 'index'])->name('home');
Route::get('text/generate', [App\Http\Controllers\OpenAIController::class, 'index']);
Route::post('/generate', [App\Http\Controllers\OpenAIController::class, 'generateText']);

Step 5: Create Controller

In this step, we will create an OpenAIController.php file using the following command.

php artisan make:controller OpenAIController

app/Http/Controllers/OpenAIController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use OpenAI\Client;

class OpenAIController extends Controller
{   
    public function index()
    {
        return view('text_generate');
    }

    public function generateText(Request $input){
        if ($input->title == null) {
            return;
        }
    
        $title = $input->title;
        
        $client = OpenAI::client(env('OPENAI_API_KEY'));
    
        $result = $client->completions()->create([
            "model" => "text-davinci-003",
            "temperature" => 0.7,
            "top_p" => 1,
            "frequency_penalty" => 0,
            "presence_penalty" => 0,
            'max_tokens' => 600,
            'prompt' => sprintf('Write article about: %s', $title),
        ]);
    
        $content = trim($result['choices'][0]['text']);

        return view('text_generate', compact('title', 'content'));

    }
}

Completions:

the model will return one or more predicted completions, and can also return the probabilities of alternative tokens at each position.

Step 6: Create Blade File

In this step, we will create a text_generate.blade.php file.

resources/views/text_generate.blade.php

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">
    <head>
        <meta charset="utf-8">
