Yes, it works great! I've been using this in all of my projects. Was super easy to use out of the box with this package.

Although it's straight forward, might be worth adding an example to the README.md for others searching for the feature across PHP GitHub projects.

Adding PR here:

$complete = $open_ai->chat([
    'model' => 'gpt-3.5-turbo-1106',
    'messages' => [
            [
                'role' => 'system',
                'content' => 'You are a zoologist.'
            ],
            [
                'role' => 'system',
                'content' => 'Respond with JSON. Use this structure: [{"animal":"","description":""}]'
            ],
            [
                'role' => 'user',
                'content' => 'Supply a list of the most common animals you would see in a zoo.'
            ],

]);

Just a quick note for everyone whoe stumpled over this issue.

$open_ai->completion([…]); won't work due to error Unrecognized request argument supplied: response_format.

But $open_ai->->chat works:

$result = json_decode($open_ai->chat([
	'model' => 'gpt-3.5-turbo-1106',
	'messages' => [
		[
			'role' => 'system',
			'content' => 'Respond with JSON. Use the provided keys to answer the question.',
		],
		[
			'role' => 'user',
			'content' => $prompt
		],
	],
	'temperature' => 1,
	'max_tokens' => 3500,
	'response_format' => ['type' => 'json_object']
]), false, 512, JSON_THROW_ON_ERROR);

Have fun.
