[Bug]: Undefined array key "usage" with Vision endpoint on Azure

[pimverbij]

Description

I'm trying to use vision on Azure, this was working before.

It seems that Azure has changed the format of their response for the Vision endpoint.

I am creating the client with the factory etc. But since today the code that had been working has stopped working.
This results in the error Undefined array key "usage"
I'm running the latests version of the client.

Steps To Reproduce

         $baseUri = 'https://tellet-azure-sweden.openai.azure.com/openai/deployments/tellet-gpt-4-vision-preview';
        
        $client = OpenAI::factory()
        ->withBaseUri($baseUri)
        ->withHttpClient(new \GuzzleHttp\Client(['timeout' => 300, 'connect_timeout' => 300]))
        ->withHttpHeader('api-key', $apiKey)
        ->withQueryParam('api-version', '2023-12-01-preview')
        ->make();
        
         $base64Image = $this->imageToBase64($image);
         $encoded = 'data:image/jpeg;base64,'.$base64Image;

    $imageArray[] = [
        'type' => 'text',
        'text' => 'Analyse this photograph and provide a detailed description of its contents. Focus on identifying and listing all visible items, with particular attention to food items present. '
    ];
    
    $imageArray[] = [
        'type' => 'image_url',
        'image_url' => ['url' => $encoded]
    ];

    $messagesArray = array();
    $messagesArray[] = [
        'role' => 'user',
        'content' => $imageArray
    ];
    
    $settings['messages'] = $messagesArray;
    $settings['max_tokens'] = 1200;
    $settings['messages'] = $messagesArray;
    $response = $client->chat()->create($settings);

Doing some more digging and it looks like this specific model is not returning the "usage"
