Is this a world record? The GPT 5.5 ran for 19 hours

Oh god… Not a good idea just typing continue with codex. You’re asking for trouble and with 5.5 you’re literally throwing away money. Please tell me you at least used an exit strategy prompt. For example “continue. If blocked on a specific user decision/action, output exactly one line: [[WAITING_FOR_INPUT:]].”

These bots require precise prompting. Doing what you’re doing allows it to run off on tangents and will code indefinitely. That’s why they’re saying 42 too you.
