Codex code leak reveals Aeon, OpenAI's rumored persistent agent, launch may be imminent
ChrisGPT · x · 2026-09-22
A developer digging through Codex's shipped code found multiple references to Aeon, OpenAI's rumored persistent agent:
- Model-selection fields: aeonModelId and allowAeonDraftModelSelection
- Name/appearance fields: aeonDraftName and aeonDraftAppearance
- Cloud-environment selection and a dedicated thread/startAeon operation
- Aeon references tied directly to the "Agents" sidebar
The community has also reported aeonId and memberAeonIds in ChatGPT's web and Android code, plus purported aeon-core instructions describing a persistent agent that coordinates cloud tasks and automations. The author reads this as groundwork for configurable agents inside Codex, with community rumors suggesting GPT-Astra contributed and a launch possibly coming Thursday or at DevDay. The references were verified in the inspected build, though some paths remain disabled.
