Thanks for st.chat_message and st.chat_input. I updated my application to use it and it is much more responsive (and can even print out the chat). https://conversation.streamlit.app/

Your example with the streaming response from the API provides a better user experience!

A couple suggestions though…

  • if the chat window is not scrolled to the bottom it does not automatically jump to the bottom when the new response starts to come in.
  • would be nice to have a right format option for one of the discussions… like user input.
  • using local path to png files for avatar images works fine in local but fails in cloud.
  • with the chat application, sometimes the sidebar open icon disappears while run from a phone.
