OpenAI's latest SDK update (7.28.0) hints at new file search tool configurations including chunking options and a 'ranker' parameter. It also emphasizes JSON mode usage.
READY TO POST:
openai's new sdk update includes some interesting details about file search tool overrides, like chunk_overlap_tokens and max_chunk_tokens. curious how this will improve search results!
looks like openai might be adding a 'ranker' option to some tools, with a default_2024_08_21 value. also, more explicit guidance on using json mode for consistent outputs.
