How do I use finetuned models?

[badjano]

Copilot suggested me this but I think he made it up:

$result = $client->chat()->create([
    'model' => 'gpt-4o-mini',
    'messages' => [
        ['role' => 'user', 'content' => $msg],
    ],
    'fine_tune_job_id' => $fineTuneJobId,
]);

nevermind, apparently the finetuning id goes in the model field
