LGTM @dawoodkhan82! Could we add a story for this as well?

Does this work for gr.ChatInterface?

Does this work for gr.ChatInterface?

@abidlabs Should we add chat_bubble_width as a param on gr.ChatInterface? Or maybe make it full_width be default.

[abidlabs]

Not necessary, you can pass in a custom Chatbot instance as the chatbot parameter to gr.ChatInterface to get this behavior.

See this Space by @yvrjsharma for example: https://huggingface.co/spaces/ysharma/falcon-180b-demo/blob/92739960e894d417f240b2ec6f55e92ab6b0c788/app.py#L124

@abidlabs thanks for this useful feature.

Is the possible add further a max_width here when full_width is false?
