OpenAI's latest SDK update (7.18.0) hints at new `file_search` tool features like `chunk_overlap_tokens` and `chunk_size_tokens`, potentially improving search relevance. It also introduces a new `ranker` option with a `default_2024_08_21` value, and mentions `JSON mode` which forces JSON responses.
READY TO POST:
openai's new sdk hints at deeper controls for file search, including chunking and overlap settings. this could mean much more precise retrieval for rag!
new 'json mode' in the openai sdk seems to ensure valid json output from models. goodbye parsing errors? also seeing a new 'ranker' option.
