I love the method you used to get image consistency: construct a conversation history with the model where it explicitly accepts each image and agrees to use it:

  User: Previous page prompt: [Previous Prompt 1]
  User: [Image 1]
  Assistant: I've received this image and will maintain visual consistency with it.
  User: Previous page prompt: [Previous Prompt 2]
  User: [Image 2]
  Assistant: I've received this image and will maintain visual consistency with it.
  User: Previous page prompt: [Previous Prompt 3]
  User: [Image 3]
  Assistant: I've received this image and will maintain visual consistency with it.
  User: Please maintain character appearance, art style, and color palette consistency with these previous illustrations when creating the next image.
  Assistant: I'll ensure the characters, art style, and colors remain consistent with the previous illustrations.
  User: Generate an illustration for a children's ABC story: [Current Prompt]. Make it colorful, child-friendly, and in a consistent style with any previous images. Include diverse characters with different ethnicities, genders, and abilities. Ensure representation is natural and authentic.

I'm curious: did you settle on this after trial and error? I mean, did having the assistant explicitly agree increase consistency, compared with just asking nicely at the end?

The quality of the images is incredible! Great job

How much does the api cost to run? Do you have any safe guards in place in case bots try to build 1000 stories?

wow!!!!

Any idea how much it costs to create a book?
