1. Ask HN: How do you feel about the new $500 OpenAI subscription?

So it seems like there'll be a new $500 plan. It's been incredibly frustrating to have the quality of the subscriptions vary wildly. The model intelligence and quality is incredibly opaque, and it feels like they sometimes just switch the labels out. I am quite worried that they're going to downgrade everything, and what we have now for 5x or 20x (which they don't even offer anymore) is going to be moved to the new promax plan at 500 big ones.
