I've given this some more thought. Even if Imagen 4 isn't that great on its own, all of Google's models and UX products in conjunction (Veo 3, Flow, etc.) are orders of magnitude above the rest of the playing field.
If Tencent wants to keep Google from winning the game, they should open source their models. From my perspective right now, it looks like Google is going to win this entire game, and open source AI might be the only way to stop that from being a runaway victory.
