Had to test the new Kling 4.0 flash against Kling 3.0 to see how much better the model improved from previous ones. I think #Kling4 was a lot better with sound and prompt adherence and also general visual and physics. But then I noticed Kling3 was better at expressions and emotions. Ofcourse this is just the flash model, I believe Kling 4.0 would be better, I can’t wait.
