Well, not none of it, to be entirely nitpicky, as they've already must have sent data at first to have received the rejections :) In the end, it ended up being OpenAI's agent actions anyways so doesn't really matter, and the credentials it seems like the agent also had gotten to those too already. Still, I'm sure they'll look differently at hosted/restricted models after this event, as will many others.
