OpenAI's latest SDK hints at new 'file_search' tool overrides with chunking controls, a 'ranker' option, and expanded JSON mode guidance.
READY TO POST:
looks like openai's file search tool might be getting chunking controls with new max tokens and overlap settings. more granular control for retrieval?
openai's latest sdk update mentions a 'default_2024_08_21' ranker. possibly a new ranking model for assistants or file search coming soon.
