There are two new kinds, and two existing ones take more information:\n\n- Elapsed-time reminder: added when the model in use qualifies for it.\n\n- Proactivity note: tells the model a proactivity level and a set of tools, or tells it that this has been withdrawn.\n\n- Total-tokens reminder: now also takes a budget.\n\n- Silent-turn reminder: now also receives the model in use and the current time.\n\n**Why**\n\nThe model will receive new reminder text, which can change how it paces itself and how much it acts on its own.\n\n- Area: System Reminders\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 4\/5\n- Scope: individual\n- Heads-up: no"}
