OpenAI is about to drop "o", its always-on agent, reportedly running on Aeon, the long-horizon variant of GPT-6 Astra. Not a chatbot. An agent that keeps working after you close the app. Meta thought Muse had this locked up after JPMorgan crowned it #1. That lead might last exactly one keynote. The 3 use cases that actually matter: 1️⃣ Inbox & calendar on autopilot. Triage, replies, scheduling, follow-ups. You wake up and it's already done. 2️⃣ End-to-end errands. Research, compare, book, buy. From "I need X" to confirmation, zero tabs open. 3️⃣ Long-running background work. Monitoring, routines, multi-hour tasks that keep going while you sleep. Set your alarms fammm, devday will be huge!
