My bad. I should have done a better job with setting up some kind of changelog 
Fair point. Perhaps at some point, Open AI will start doing this and providing multiple lightweight SDKs themselves. In the meantime, my goal was to mirror the complete Open AI SDK in as lightweight a manner as possible.
Based on user feedback/PRs the openai_ex library layered on functionality that I myself was not using / testing (Azure support, Finch pools, Local LLM streaming tweaks, Portkey support, deviations from SSE standards, api key log redaction, etc.) A lot of knowledge from actual use has been baked into the library at this point.
OTOH, it’s unclear if any of this will be important for the Responses API, so perhaps it is a good decision to keep it separate and lightweight.
Another option might be to use ‘openai_ex’ to do the actual call and have a library that provides functionality that layers on top, such as your 'text_deltas" function. I considered adding these helpers at some point but decided that I didn’t understand the individual use cases well enough to decide what was appropriate for everyone.
Good luck with the project in any case
