The realtime one they showed yesterday or the one that's existed forever where it's just a voice-to-text input and TTS output taking turns?

I feel silly now. I downloaded the app after the announcement (I'm a desktop user) and it looked identical to the one they show in the sarcasm video. When I asked it, I was told it was not the new feature announced yesterday. Still a lot of fun!

Edit - it does list the new model in my app at least
