From Readme:

The chat frontend is now live here. Log in and start chatting! Please try to react with a thumbs up or down for the assistant's responses when chatting.

but the link now leads to the OpenAssistant has finished! page, without allowing you to try the model

I'll like to work on this.
I will update the link in the readme file to the correct link and verify that the link leads to the correct chat frontend. Finally, I will test the chat functionality to ensure it is working as expected.

This issue seems to be more on the Open Assistant side. If you try to go to the homepage, it redirects to the OpenAssistant has finished page. If you try to go to the dashboard, you're automatically redirected to the OpenAssistant has finished page.
