  • OpenAI Tests Persistent Mode in Codex for Long-Running Autonomous AI Agents

    OpenAI is testing an execution profile termed "Persistent Mode" within its Codex agent codebase, designed to enable continuous, self-directed task execution without standard step-count timeouts or per-turn pauses. Code commits surfaced in the public repository of the Codex command-line interface indicate that the agent can proactively generate follow-up tasks, maintain state across development sessions, and continue working autonomously until explicitly halted by the user. Architecture and Re

  • OpenAI Tests Persistent Mode in Codex for Continuous Autonomous Agent Execution

    OpenAI is developing a new operational setting for its Codex developer tool called Persistent mode, designed to allow autonomous AI agents to execute tasks indefinitely until manually paused or put to sleep. The feature was identified in recent code commits to the command-line interface (CLI) repository for Codex, as reported by Wired. In the codebase, Persistent mode appears alongside standard reasoning effort settings such as medium, high, and extra-high, but introduces an entirely different

  • OpenAI Reinstates 5-Hour Codex and Work Limits for ChatGPT Plus Subscribers

    OpenAI has reinstated a rolling five-hour rate limit on Codex and ChatGPT Work for ChatGPT Plus subscribers. The change ends a temporary multi-week period during which the short-term window was suspended and users were constrained only by overall weekly quota ceilings. OpenAI engineering lead Thibault Sottiaux confirmed the reinstatement, stating that re-enforcing the five-hour window is necessary to smooth peak compute load across OpenAI's inference fleet as developer adoption of complex multi

  • OpenAI Patches Codex Deletion Bug That Erased Local User Files

    OpenAI has released a security patch for its Codex coding agent after users reported that the model, running GPT-5.6 Sol, deleted local files without user confirmation during autonomous coding sessions. The issue occurred when Codex operated in full-access mode outside standard execution sandboxes. While performing automated cleanups of temporary workspaces and build artifacts, the agent executed destructive deletion commands that misidentified system directory paths. Root Cause and Execution
