Update Image Caption

Update the caption of a specific image. There are two mutually exclusive ways to update a caption:

1. Provide a new caption text:

   • Use the caption parameter
   • This will set caption_source to "manual"
   • Reflects a human-written caption

2. Request automatic caption regeneration:

   • Set regenerate_caption to true
   • This will set caption_source to "automatic"
   • A new caption will be generated automatically based on the image and caption_prefix
   • For the same caption_prefix, regenerate_caption will always return the same caption
   • Useful for resetting captions or regenerating them after changing the caption_prefix

Note: You cannot provide both parameters simultaneously as they represent different update approaches.

Constraints:

• Cannot update captions in a completed dataset
• Cannot provide both caption and regenerate_caption in the same request
