That’s voice chat which has been there for a long time.
The 4o voice model is different. 4o can chat much more naturally, and you can interrupt the voice chat in 4o.
Try it, you can’t interrupt the chat unless you touch the screen.
You can go back to see the 4o voice chat demo, and you will find out which different it is.
An excellent film but I wouldn’t call it “without sound”. In fact sound is extremely important in this film. It’s more like “without spoken words”.
