OpenAI's 7.40.0 npm package hints at new 'ranker' options, refined file search chunking, and clearer JSON mode guidance.

READY TO POST:

openai's latest npm package has a new 'ranker' option, 'default_2024_08_21'. could this be a new relevance model for assistants or search?

new strings in openai's npm package show more control over file search chunking and overlap, plus clearer guidance for json mode. good for dev control!
