Original GitHub issue: https://github.com/Mintplex-Labs/anything-llm/issues/4814

What would you like to see?

Hi,

When using AnythingLLM local with the /stream-chat endpoint, the stream sends extremely small chunks (often single characters).

This causes serious rendering issues for RTL languages like Persian, resulting in broken spacing and unreadable output unless complex client-side buffering is implemented.

Is there a way to:

  • Stream larger chunks?
  • Or respect word boundaries for RTL languages?

Thanks!

This is related to the issues in layout from #3430, if we patched the UI totally, including the layout issues it would also fix this issue as well as text would be appended in the correct layout automatically.

The blocker for this was that the layout for RTL causes a ton of oddities beyond just text direction and instead moves elements all over the page

The chunk separation for any RTL language is entirely dependent on the model provider, nothing we can control for that since all we get back are the chunks including spacing/newlines. There is nothing we can do to patch this specific issue aside from an overall RTL implementation which is nontrival and breaks the entire UI
