Its reference appeared briefly on the ChatGPT upgrade screen for some users.
Internal config has references to "o" as a display name and "-o" as an email suffix. This means that "o" will support email handling.
OpenAI is hosting its DevDay next week, where we will likely hear more about their always-on assistant.
P.S. A rumored "Aeon" reference is an internal name for the existing custom Agents implementation for ChatGPT Workspace accounts. Yet OpenAI will likely build a consumer-facing "o" assistant on top of this feature.
Next week will be huge. I also like that Meta set a super high standard with its Muse assistant. OpenAI will need to cross a very high bar.
Soon? ๐
