So I was experimenting the excellent post by @dlaytonj2 here on batch api here Fun with the Batch API - An example

And decide to give your first page a go with text recognition from gpt-4o-mini in batch. I can successfully get the multi columnar thing to read properly.

The key insight was to provide the format in the system_context and the user_context

SYSTEM_IMAGE_READER_CONTEXT = “You are an expert at reading text in the image.”
USER_IMAGE_READER_CONTEXT = “The format is structured in multiple columns. Obviously the text must follow as a human would read it.”

Can you please take a quick look at let me know if the raw text extraction looks ok?
