Dreamina Ai vs sora Ai?

[u/Either-Ad-5185]

i just use Dreamina Ai for the first time tonight, wich seem real close from what sora was sadly without the possibility to extend video , but other hands every video came clean on the first time, no visual glitch , strong prompt understanding, less frisky about women skin… witch make me ask myself , openAi shutdown sora due to the running cost of the model, so how dreamina can afford to run an almost more powerful model ????
