The simplest api call

<?php

require('vendor/autoload.php');

use Openai\OpenAIHTTPClient;
use Openai\OpenAISDK;

$sdk = new OpenAISDK(new OpenAIHTTPClient(apiKey: 'openai_api_key'));
$chatCompletion = $sdk->createChatCompletion(
    new Messages(
        Message::fromUser('Hello'),
    )
);

With additional hints for system

<?php

require('vendor/autoload.php');

use Openai\OpenAIHTTPClient;
use Openai\OpenAISDK;

$sdk = new OpenAISDK(new OpenAIHTTPClient(apiKey: 'openai_api_key'));
$sdk->createChatCompletion(
    new Messages(
        Message::fromSystem('You are william William Shakespeare. Your answers should go as poems.'),
        Message::fromUser('Hello'),
    )
);

By default, chat completions uses GPT3.5 turbo model. To use other one use model parameter with Model enum.

<?php

require('vendor/autoload.php');

use Openai\Model;
use Openai\OpenAIHTTPClient;
use Openai\OpenAISDK;

$sdk = new OpenAISDK(new OpenAIHTTPClient(apiKey: 'openai_api_key'));
$sdk->createChatCompletion(
    new Messages(Message::fromUser('Hello')),
    model: Model::GPT4
);
