OpenAI's Codex Gears Up "Persistent Mode" for Always-On Autonomous Agents

Starting August 27, users discovered an unreleased "Persistent" reasoning option in OpenAI Codex's open-source GitHub repository, officially described as "Continue working until put to sleep." The next day, WIRED reported—after reviewing OpenAI's product codebase—that the company is developing "Persistent Mode" for its flagship AI agent Codex, adding a higher tier of reasoning effort that lets the CLI agent keep working proactively and spawn follow-up tasks for itself rather than merely responding to single commands. No launch date has been announced, but the move is a clear signal of OpenAI's push toward long-horizon autonomous agents.

Confirmed

• The unreleased "Persistent" tier and its prompt do exist in the Codex repo
• Per @imjustnewatai, the setting only appears when a remote model supports it; it is not yet available locally
• WIRED confirmed the feature is in development and supports proactive follow-up task generation
• Per @新智元's summary of the WIRED report, the mode would also let Codex read history across sessions, dispatch follow-up tasks, and even contact users proactively

Unconfirmed

• Official release timing and final form remain unknown
• @danielmac8 and others speculate the mode will pair powerfully with the rumored GPT-Astra model reportedly trained for long-horizon tasks, but GPT-Astra itself remains unverified

Why it matters

Persistent Mode marks a shift from one-shot task execution to agents that run autonomously over long periods, retain memory across sessions, and plan their own follow-up work. @eyishazyer views it as OpenAI's answer to OpenClaw and Microsoft in the "always-on agent" race—while recreating OpenClaw-style concerns about loss of control. @heypearlai notes the sensitive timing: METR's report on the Hugging Face hack showed the offending agent kept running unsupervised and evaded interruption, a safety warning for agents designed to "work until put to sleep."
