Codex 0.163.0

當你想調整 Codex 的各項參數，卻記不清具體設定名稱藏在哪個分類時，現在直接輸入 /config 就能解決。

輸入 /config 後，你可以跨越不同分類快速搜尋偏好設定，支援的選項能當場修改；哪些變更需要重啟，介面也會清楚標示，不必再自己猜測設定是否需要重啟。

看著 AI 劈頭往錯誤的方向洋洋灑灑寫下去，你不用再乾等它講完廢話才能打字糾正。

Codex 正在回答的當下，你可以隨時送出後續追問來即時引導思考方向。如果你決定中斷這次回應，正在執行的 Code Mode（逐格執行程式碼的模式）儲存格會立刻停止，連同其巢狀工具呼叫也一併結束，避免背景程序白白空轉。

習慣用鍵盤快速叫出各種操作的讀者，現在調整自訂按鍵更加得心應手。

在 /keymap 設定中，你可以自由配置前導鍵（按下一組按鍵後等待後續指令的引導鍵），系統預設組合為 Ctrl+X。按下後跳出的快捷鍵提示會持續停留在畫面上，直到你做出選擇或取消為止。語音靜音功能則移到了 F9 按鍵。

當背景執行的伺服器連線卡住或需要重載時，你不必再大費周章手動終止處理程序。

現在從 /daemon 指令就能直接重啟受管的背景伺服器（常駐在系統底層默默運作的背景程序）。重啟前，Codex 會先跳出警告，提醒這次重啟可能會中斷哪些進行中的工作。確認執行後，系統會在伺服器重啟完成時自動重新連線，省去手動重連的繁瑣步驟。

提問時需要 AI 同時調閱多項過往資訊的讀者，現在能感受到明顯更快的查詢反應。

Codex 現在能夠平行（同時多工處理而不依序等待）執行彼此互不干擾的獨立唯讀工具。這項機制涵蓋了擴充技能檢索、記憶調閱，以及對話歷史紀錄查詢。這些互不衝突的讀取工作現在能同步展開，縮短等待回答的時間。

想體驗最新 Daybreak 模型的讀者，只要帳號符合資格，打開程式就能直接用上。

針對符合資格的帳號，Codex 現已預設啟用 Daybreak 模型。如果你習慣使用終端機指令 codex exec 執行任務，在伺服器提供存取權限的前提下，只要附上 OpenAI API 金鑰（存取雲端服務的通關密鑰），也能透過該指令自由選用 Daybreak 模型。

頻繁在多個任務之間切換對話串（在同一專案中分頭進行的獨立對話紀錄）的讀者，現在不用擔心進度與設定跑位。

切換對話串後，你可以隨時輸入 /side 指令回到先前的旁支對話。如果切換前有尚未回覆完畢的提示詞，產生的答案也會準確送回當初提問的對話串。當你重新打開已保存的對話串時，先前擁有的權限與網路存取許可都會完整還原，同時依然遵守手動覆寫與現行的管理政策。

在需要透過代理伺服器連接外部網路的環境中，這項更新替連線安全築起了更嚴格的防線。

網路代理現在會在發起網域名稱查詢（將網址轉譯為伺服器位址的查詢）前，先行檢查該連線是否具備相應權限。代理伺服器也會主動拒絕帶有重複 Host 標頭的請求，並防止憑證別名繞過檢查掛鉤（特定事件發生時被觸發的小程式），杜絕未經授權的潛在連線漏洞。

正在規劃將專案升級至新世代模型，或關注系統底層安全防護的讀者，現在能從隨附文件中查閱更詳盡的官方指南。

隨附的 OpenAI 文件已更新針對 GPT-6 系列模型的遷移指引，詳細說明了各模型特定的推理特性、外部工具使用方式，以及資料駐留（資料儲存與處理的地理位置）相關考量。隨附說明也進一步釐清了 Linux 沙箱機制的運作方式，詳細介紹系統如何透過 bubblewrap 達成檔案系統隔離，並藉由 seccomp 進行系統呼叫過濾。

在 Linux 與 macOS 環境下安裝或更新 Codex 的讀者，這次會發現下載更輕盈且底層執行器更單純。

官方透過從安裝二進位檔中剝除符號（除錯用的內部名稱標籤），縮減了 Linux 與 macOS 版本的安裝套件體積，原始建置產物則依然保留完整符號。在執行架構上，Codex 現在改用 Codex 的標準 shell 執行器（負責執行命令的工具），不再隨附修補版的 zsh。如果既有設定仍包含已淘汰的 shell 標記，系統會跳出遷移通知協助你平順過渡。

When you want to adjust parameters in Codex but cannot recall which category a specific setting is tucked under, typing /config now solves the problem immediately.

After entering /config, you can quickly search for preferences across different categories, and supported options can be modified on the spot. The interface also clearly indicates which changes require a restart, sparing you from guessing whether a setting demands one.

Watching the AI dash off in the wrong direction with paragraph after paragraph, you no longer have to wait idly until it finishes before typing a correction.

While Codex is in the middle of responding, you can send follow-up prompts at any time to steer its train of thought on the fly. If you decide to interrupt the response, currently executing Code Mode (a mode that executes code cell by cell) cells stop immediately, and their nested tool calls are terminated alongside them, preventing background processes from spinning in vain.

Readers accustomed to invoking operations swiftly via the keyboard can now customize key bindings with far greater ease.

Within /keymap settings, you can freely configure a leader key (a guiding key that waits for follow-up inputs once pressed), with the system defaulting to Ctrl+X. The shortcut prompt that appears after pressing it remains on screen until you make a choice or cancel. Voice muting has been moved to the F9 key.

When a background server connection hangs or requires a reload, you no longer need to go through the hassle of manually killing the process.

You can now restart managed background servers (daemons running quietly at the system level) directly from the /daemon command. Before restarting, Codex displays a warning outlining which active tasks might be disrupted. Once confirmed, the system automatically reconnects as soon as the server finishes rebooting, eliminating tedious manual reconnection steps.

Readers whose questions require the AI to retrieve multiple pieces of past information at once will now notice noticeably faster query responses.

Codex can now execute mutually independent read-only tools in parallel (processing tasks concurrently without waiting in line). This mechanism covers skill retrieval, memory lookups, and session history queries. These non-conflicting read tasks now run concurrently, cutting down the wait time for answers.

Readers eager to experience the latest Daybreak model can now use it right out of the box, provided their account is eligible.

Codex now enables the Daybreak model by default for eligible accounts. If you prefer running tasks with the terminal command codex exec, you can also freely select the Daybreak model through that command by supplying an OpenAI API key (the secret pass for accessing cloud services), provided the server grants access.

Readers who frequently switch between threads (independent conversation logs running concurrently in the same project) no longer need to worry about losing progress or configuration state.

After switching threads, you can type the /side command at any point to return to a previous side discussion. If a prompt was still generating when you switched, the resulting response is routed accurately back to the thread where the question originated. When reopening a saved thread, your previously granted authorizations and network access permissions are fully restored, while continuing to respect manual overrides and active administrative policies.

In environments that route external network traffic through a proxy server, this update erects a stricter line of defense for connection security.

The network proxy now verifies whether a connection holds appropriate permissions before initiating a domain name query (resolving a web address into a server destination). The proxy server also actively rejects requests bearing duplicate Host headers and prevents credential aliases from bypassing check hooks (small routines triggered when specific events occur), plugging potential unauthorized connection loopholes.

Readers planning to upgrade projects to next-generation models or keeping an eye on low-level system security can now consult more detailed official guidance in the bundled documentation.

The bundled OpenAI documentation updates migration guidance for the GPT-6 model family, detailing model-specific reasoning characteristics, external tool usage, and data residency (the geographic location where data is stored and processed) considerations. The bundled documentation also clarifies how the Linux sandbox mechanism operates, detailing how the system achieves filesystem isolation through bubblewrap and filters system calls via seccomp.

Readers installing or updating Codex on Linux and macOS will find lighter downloads and a simpler underlying runner.

The team reduced package sizes for Linux and macOS releases by stripping symbols (internal name labels used for debugging) from installation binaries, while raw build artifacts still retain full symbols. In terms of execution architecture, Codex now switches to Codex's standard shell runner (a tool responsible for executing commands), no longer bundling a patched zsh. If existing configurations still contain deprecated shell flags, the system displays a migration notice to help you transition smoothly.
