Live, interruptible, wake word
One live Gemini session carries the conversation. She listens and speaks natively and can use a tool mid-sentence, so a simple answer starts in about a second.
Say "Hey Jarvis" to wake her, or hold the shortcut. Talk over her and she stops and follows the new instruction. If the connection drops she reconnects on her own and carries on where you were.
Hard questions, maths, an error on your screen, a real decision, go to a thinking model first. You hear that she is on it, then the answer.
“Hey Jarvis, what is this error on my screen?”
