The GPT Image model (gpt-image-2.6, alias gpt-image-latest) has these keys:

• aspectRatioobject

  A select field: "auto", "1:1", "16:9", "9:16"… Default "auto"

• imageResolutionobject

  A select field with options "1k" (1K) and "2k" (2K). Default "1k" — the web picker's. Over the API the field is resolution, and leaving it out means "original" (see GPT Image)

• maxRefImagesnumber

  A plain number, not a field: how many reference images the model takes. 20 for GPT Image

The list may also hold the older video tools (video, voiceovervideo, stockvideo, slideshowvideo, articlevideo, render). They are moving to Motion and are not documented.
