What shipped ChatGPT, Oct 20: Locked chats. Lock a chat and it disappears from your history, pinned chats and search until you open it again with a PIN or your device login. Rolling out to Free, Go, Plus and Pro. ChatGPT, this Thursday, Oct 29: the grandfathered Pro $200 allowance ends. If you've been on Pro $200 since before it reopened on Sept 29, your old allowance ends that day. OpenAI still hasn't published the new number. What it means for your plan On Pro at $200 from before Sept 29? Check how close you run to your limit this week, before Thursday. The Plan Stretcher in The AI Masterclass lists what burns usage fastest, and I added this change to it today. Claude Duet, from last week's Release Radar, also counts its background checks against Claude limits, so wait on it if you already hit your 5-hour window. One thing to try in 15 minutes Open your Brain OS Project and ask: "Read 04-decisions. Which decision am I most likely to second-guess this week, and what would have to change for me to revisit it?" If the answer is vague, your decisions block is too thin. Add one decision with its date and what you considered instead, then ask again.
