One option we've been testing is the 'maintainFormat` mode. This tries to return the markdown in a consistent format by passing the output of a prior page in as additional context for the next page. Especially useful if you've got tables that span pages. The flow is pretty much:

- Request #1 => page_1_image

- Request #2 => page_1_markdown + page_2_image

- Request #3 => page_2_markdown + page_3_image
