You’re right, but in fact right now Sam’s policy, and OpenAI’s, is to offer such a subscription even though no other company, not Google, not Anthropic, not X.AI, offers unlimited. That means they have some reasoning behind it, so I think they will agree.
You have to understand that they want developers to move over to them, and if there’s something they can offer that will get developers to switch from Anthropic, it’s worth it for them.
