Steps To Reproduce

Create a factory like

<?php

declare(strict_types=1);

namespace App\OpenAI;

use OpenAI\Client;

/**
 * @author Oskar Stark <oskarstark@googlemail.com>
 */
final readonly class OpenAIClientFactory
{
    public static function create(string $apiKey): Client
    {
        return \OpenAI::factory()
            ->withApiKey($apiKey)
            ->withHttpHeader('OpenAI-Beta', 'assistants=v2')
            ->make();
    }
}

and use it like:

<?php

declare(strict_types=1);

namespace App\OpenAI;

use App\OpenAI\Value\Answer;
use App\OpenAI\Value\AssistantId;
use App\OpenAI\Value\ThreadId;
use OpenAI\Client as OpenAI;
use OskarStark\Value\TrimmedNonEmptyString;

/**
 * @author Oskar Stark <oskarstark@googlemail.com>
 */
final readonly class Assistant
{
    public function __construct(
        private OpenAI $openAI,
    ) {
    }

    public function ask(AssistantId $assistant, string $question): string
    {
        $thread = $this->openAI->threads()->createAndRun([
            'assistant_id' => $assistant->value,
            'thread' => [
                'messages' => [
                    [
                        'role' => 'user',
                        'content' => $question,
                    ],
                ],
            ],
        ]);

        $done = false;

        while (!$done) {
            $run = $this->openAI->threads()->runs()->retrieve(
                threadId: $thread->threadId,
                runId: $thread->id,
            );

            if ('completed' === $run->status) {
                $done = true;
            }
        }

        $messagesData = $this->openAI->threads()->messages()->list(
            $thread->threadId,
        );

        $message = '';

        foreach ($messagesData->data as $messageData) {
            $message = $this->openAI->threads()->messages()->retrieve(
                threadId: $thread->threadId,
                messageId: $messageData->id,
            )->content[0]->text->value;

            break;
        }

        var_dump($message);

        return $message;
    }
}
