OP seems to be on the "They secretly trained on her voice" train. The only reason "Two Days!" would be damning is if a finetune was in order to replicate ScarJo's voice. In that sense, it's much better.

Open AI have launched nothing. There's no date for new voice mode other than, "alpha testing in the coming weeks to plus users". No-one has access to it yet.
