If I were to get conspiracy-minded:
Sora had to be shut down because it was the clearest, most consequential demonstration that OpenAI’s models are running way, way ahead of their ability to align/jail them effectively.
What did Sora do?
probably more cost than anything. image and video gen don't have much in common with llms
Nope. It was just a bad product that no one wanted. It’s not a super-secret indicator that OpenAI is actually going to take over the world any day now.
The Occam's Razor position (Sora was the most expensive to operate, least monetizable model) seems like a simpler explanation. The legal costs/difficulty on top of "most expensive" are just the cherry on top.
