[Enhancement] streaming support for assistant api

[mgalinskiSaticon]

As opposed in the following Q&A, OpenAI has published the support for Message Streaming for the Assistant API, which has been documented. As such I want to open an issue for it.

I was thinking of opening the same thing and was looking at the other completion stream implementations to try and implement myself but didn't make much progress. Would love this feature to be added

Need this feature for my project too. I'm looking forward to it

Is anyone already working on the feature? Is there anything I can do to help?

Just created a PR for this, It maps each event onto the correct object classes. So you can loop through the stream and perform whichever actions you want at each event.

Im fairly sure its feature complete, but let me know if anything might be missing from it. Its working fine on my project so far.

+1 for streaming assistant support pretty, pretty please.

Any updates on it. We are blocked due to not having this feature.

Thanks, Sarathi
