Codex Replay

ChatGPT plugin

Run independent replays in the in-app or system browser.

View in ChatGPT directory

Start an independent Codex Replay controller on an available loopback port. In both Codex Desktop and Codex CLI, prefer an available Codex in-app browser and otherwise use your system browser. Select one or more historical Claude threads, choose shared Codex models, and start their isolated implementations. Historical state and configuration are detected separately for each thread, with details available when needed. View finished comparisons individually or in aggregate while remaining threads continue. Available GPT-5.6 Sol, Terra, and Luna models are selected by default. Multiple replay sessions can run in parallel. Selection, execution, verification, evaluation, and results stay in the browser controller instead of a guided chat workflow.

Skills

  • codex-replay

    Open an independent Codex Replay controller in the Codex in-app browser, or the system browser when no in-app opening path is available. Use whenever this plugin is invoked or the user asks to browse, configure, run, or review a replay. The browser controller owns the entire workflow; do not conduct it in chat.
