It’s absolutely on purpose, everything is with these people.

For example if you ask Claude chat to write something of a certain length, it won’t, it’ll just reply at the same length as everything else. Why? Because they’re billing at a fixed price. They don’t want you to get a whole essay as an answer because you’re on a plan.

Claude code on the other hand, which is supposedly the same model, will happily write out a billion lines because it is billed by the token.
