Describe the bug

When making a chat completions request to gpt-4o-audio-preview or gpt-4o-mini-audio-preview, the usage response contains text_tokens and image_tokens under prompt_tokens_details:

"prompt_tokens_details": {
      "cached_tokens": 0,
      "audio_tokens": 21,
      "text_tokens": 11,
      "image_tokens": 0
    },

These fields aren't documented or typed in any schemas (also in the js sdk)
