In general, guys clearly hired some cool marketers. They were promoting the arrival of ChatGPT 5 with such pomp. When you launch a new model - even the premium background is now displayed :)
In general, I'm testing it - I'll share my thoughts later.
P.S. Unexpectedly, all previous models (including o3 and 4o and 4.5) have disappeared. Maybe it's a temporary glitch.
