OpenAI's Always-On Assistant 'o' Leaks Ahead of DevDay Keynote, Signals Shift to Autonomous Agents

OpenAI is preparing an always-on assistant called "o" that would shift ChatGPT from turn-based conversation toward persistent, autonomous operation—and newly leaked configuration files reveal the system will have email capabilities. References to "o, your always-on assistant" appeared on ChatGPT Pro upgrade screens on September 25, and the following day, internal documentation uncovered 63+ language file references for the product, complete with configuration entries for an "-o" email suffix, indicating OpenAI is preparing launch infrastructure.
