Would you use an AI agent that continues tasks after you close your chat session?
OpenAI has scheduled its DevDay keynote for 1 p.m. ET on September 29, 2026, in San Francisco. Analysts anticipate the potential introduction of a new AI agent project, currently referenced internally as O and potentially linked to project Aeon.
Why it matters
This development marks a strategic shift for OpenAI from static, single-session chat interfaces toward persistent software agents. Such tools aim to function autonomously, maintaining progress on tasks after a user exits a session.
The projected O agent is designed as an always-on system capable of processing messages and executing tasks independently. The $100 Pro upgrade benchmark indicates the company is exploring premium price points for this persistent agent capability.
The players
OpenAI
An AI research and deployment organization focused on large language models and autonomous agent development.
The details
The proposed O agent would utilize an architecture that allows for asynchronous task execution, effectively decoupling the AI from the active user chat session. By maintaining state through an internal project known as Aeon, the software could theoretically receive and process inputs without requiring a continuous open interface. References to an email suffix ending in -o found within current ChatGPT settings provide the primary technical indicators for this functionality.
Timeline
September 29, 2026: OpenAI holds its DevDay opening keynote at 1 p.m. ET.
The Tech Race
The move toward O follows the broader industry transition to autonomous AI agents currently being pursued by major technology platforms. This event marks a potential acceleration in the race to provide persistent, task-oriented AI agents.
If launched, this agent would represent a transition for users from manually prompted chat sessions to persistent software assistants that work in the background. Access to these features will likely be gated by the $100 Pro subscription tier identified in recent interface leaks.
The takeaway
The move signifies that the next frontier for generative AI is persistent task management rather than simple text completion. Observers should track the DevDay keynote for confirmation of whether O transitions from internal code to a public-facing agent.
What happens next
OpenAI will hold its keynote on September 29, 2026, at 1 p.m. ET in San Francisco, where product announcements regarding project O are expected.
