Yes, sorry, I was being maximally-broad in my comment but I would think it's very, very, very likely that OpenAI is currently charging huge margins and markups to help maintain the cachet / exclusivity / and, in some senses, safety of their service. Charging more money for access to their models feels like a pretty big part of their moat.

Also possibly b/c of their sweetheart deal with Azure they've never needed to negotiate enterprise pricing so they're probably calculating margins based on GPU list prices or something insane like that.
