Which model, 5.3 or 5.3-Codex? Yes, 5.3-Codex was announced and released. 5.3 wasn't announced. None of it is "absurd", and it also wouldn't have been "absurd" if they announce something but don't release it that same day (which they didn't do, but if they had - what exactly is absurd about that? Companies make announcements about future releases ALL the time.)
