Artificial Intelligence has become essential in modern web apps. In 2026, integrating OpenAI's latest models like GPT-4o into Laravel is easier than ever thanks to packages like openai-php/laravel and Prism.

Step 1: Installation

1. Install the package: composer require openai-php/laravel
2. Publish config: php artisan vendor:publish --provider="OpenAI\Laravel\ServiceProvider"
3. Add your API key in .env: OPENAI_API_KEY=sk-...

Step 2: Create an AI Service

namespace App\Services;

                use OpenAI\Laravel\Facades\OpenAI;

                class AIService
                {
                    public function generateResponse(string $prompt): string
                    {
                        $result = OpenAI::chat()->create([
                            'model' => 'gpt-4o',
                            'messages' => [
                                ['role' => 'user', 'content' => $prompt],
                            ],
                        ]);

                        return $result->choices[0]->message->content;
