Leak: OpenAI to Announce Always-On Agent "o" at DevDay, Possibly With Its Own Email
testingcatalog · x · 2026-09-26
TestingCatalog reports OpenAI is preparing a consumer-facing always-on agent called "o", likely announced at DevDay on September 29, where Sam Altman opens the keynote.
- References to "o" were spotted in ChatGPT's internal config as a display name, plus a "-o" email suffix — suggesting the persistent agent will have its own email identity and keep working outside normal chat sessions.
- "o" also briefly appeared as a benefit on the upgrade page for the $100 Pro plan.
- The project may be related to "Aeon," a name previously tied to OpenAI's always-on agent work and used internally for ChatGPT Workspace custom agents. Task scope, permissions, scheduling, memory, and availability remain unknown.
