Idk about that, they did that weird event pre google IO and still haven't released the features they announced.
Wouldn't be surprised if the only thing cooking is OpenAI itself.
They released the model announced in the demo but they haven't released the new way to interact with said model. I highly doubt they've got a significantly better model to release already.
I would rather they spend time on making their model smarter than cooking some gimmick to impress public or their shareholders
