    • Secure direct exec-server WebSocket connections with bearer tokens, including connections configured through app-server. (#47601, #47648)

    • Image generation and editing can explicitly request transparent backgrounds, and edits now accept file-backed conversation images. (#47484, #47956)

    • Terminal input approval is enabled by default for commands running with elevated permissions; runtime-only grants no longer cause unnecessary reviews. (#47799, #48073)

    • Fixed Windows sandbox failures involving ordinary Windows 10 paths, rejected stored credentials, and large permission policies. (#47672, #47695, #47919)

    • Fixed Linux sandbox startup with nested writable roots and preserved Git metadata protections across writable roots on Linux and macOS. (#47623, #47974)

    • macOS patch operations now recognize system path aliases covered by existing permissions, avoiding unnecessary approval prompts. (#47879)

    • Approval reviews now retry when new user input arrives, so a status question does not automatically abort a pending action. (#47819)

  • Quick chats with Pets and Appshots on Windows 26.908

    Chat while you work

    Keep ChatGPT close while you work in other apps. In the ChatGPT desktop app on macOS and Windows, you can now type a quick chat from the floating Pets controls and press Enter to send it. Use @ to add context and $ to choose a skill. Select the bell icon to follow progress in your threads, then select a thread to open the full conversation.

    Choose a companion or show just the controls in Settings > Pets. Press Option+Space on macOS or Windows+Alt+P on Windows to show the controls and focus Quick Chat. Pressing the shortcut again keeps Quick Chat open. You can change Show pet in Settings > Keyboard shortcuts. To hide the controls, select Hide pet in the command menu or Settings > Pets.

    On macOS, you can also send an appshot to the floating controls. Keep the main ChatGPT window in the background and choose Automatic for Appshot destination.

    Learn more about Pets.

    Share an app window on Windows

    Appshots are now available in the ChatGPT desktop app on Windows. Press both Alt keys to share the frontmost app window with ChatGPT, then ask a question or describe what you want to do. An appshot includes a screenshot and available text from that window. You can customize the shortcut and choose which chat receives it in settings.

    Other improvements and bug fixes

    • Open files directly from a conversation's Sources panel, or download files that ChatGPT can't preview.
    • Assign a Codex Micro key to Insert text and add your own reusable text to the active prompt without sending it.
    • Reset a pet to its default size in settings. Custom pets also stay in place when you refresh their artwork.
    • Keep unfinished comments on response text when you switch chats and return.
    • ChatGPT dictation now respects your saved Main language preference.
    • Keep tab widths and scroll positions more stable as you close browser tabs in full and split views.

  • Codex CLI Python SDK 0.154.0

    npm install -g @openai/codex@0.154.0
    View details

    Install with pip install --upgrade openai-codex==0.154.0 (Python 3.10 or later). This release includes the matching openai-codex-cli-bin==0.154.0 runtime.

    • Add max and ultra reasoning-effort values. #39662

    • Add ExternalMessage to synchronous and asynchronous run() and turn() calls. External content can start a turn or join an active regular turn with tool-level authority; it does not grant user authorization. Consumers receive independent event streams. #44086

    • Add include_turns on resume/fork, turn_service_tier for one newly started turn, and source metadata. History selection changes the returned response, not model context. Existing defaults are preserved when these options are omitted. #44084

    • Refresh generated protocol models and notifications, and preserve completion events that arrive before a turn-start response. #44032, #44400

    Check these migrations when upgrading:

    • HookMetadata wraps its handler in .root. Replace accesses such as hook.command with hook.root.command, checking hook.root.handler_type before reading handler-specific fields.

    • Some previously unknown notifications now have typed payloads. Read named fields instead of .params; unknown or invalid payloads still use UnknownNotification.

    • Manually constructed or late-joining turn handles receive events from their attachment point. Earlier output is not replayed, so collected results can be partial; attaching after completion can raise TransportClosedError. Use thread.read(include_turns=True) for saved history. Handles returned directly by thread.turn(...) retain events from when their request is sent.

    Custom codex_bin overrides require CLI 0.151.0 or newer for ExternalMessage and the new history/per-turn options.

  • Codex CLI Cygwin build inputs and matching source for Windows voice

    npm install -g @openai/codex@voice-cygwin-108b38cf67cbb731
    View details

    CI-only build tools for native Windows voice releases. These archives are not included in Codex user packages.

    • cygwin-build-inputs.tar.gz: 103 pinned Cygwin binary packages and the signed package index used by the offline build installer.

    • cygwin-build-sources.tar: all 83 corresponding source package archives at the exact versions named by that index. It includes the upstream source, patches, and build recipes provided in Cygwin's -src packages.

    • cygwin-source-map.json: each selected binary package mapped to its source archive and the source size and SHA-512 digest from the pinned index.

    • CYGWIN-SOURCE-NOTICE.txt: source access and licensing notice.

    The binary and source archive SHA-256 pins live in .github/scripts/voice-cygwin-snapshot.json in the Codex repository. Cygwin describes the licensing terms at https://cygwin.com/licensing.html. Licenses vary by package; consult the corresponding source and binary package archives for their notices.

    • Answer questions inline while Codex continues working, using suggested choices or custom text without losing your main draft. (#42891, #42894, #42897)

    • Windows sessions can now share a background Codex server, with daemon lifecycle commands and managed updates. (#42405, #42392)

    • Vim editing gains R replace mode with undo and dot-repeat, plus more reliable Escape handling in legacy terminals. (#42194, #42584)

    • Copying responses preserves formatting in rich-text apps, and /copy can copy status output or individual session fields. (#42847, #43055)

    Bug Fixes

    • Existing sessions pick up newly installed plugin tools and refresh skills and hooks after external plugin upgrades or rollbacks. (#42284, #42593, #42990)

    • MCP connections coordinate OAuth token refreshes and surface login challenges when refresh fails, without automatically replaying rejected tool calls. (#42413, #42552)

    • Startup avoids running workspace-controlled helpers before trust is established, and the macOS sandbox blocks terminal input injection. (#42324, #42590)

    • Remote resume and fork operations preserve saved permissions; fresh sessions and forks respect server model defaults unless explicitly overridden. (#43330, #43177, #43355)

    • Resuming a conversation open in another app now shows a read-only transcript with a retry option while preserving your draft. (#43253)

    • Automatic approval reviews better preserve authorization context through compaction and reject approvals invalidated by new user instructions or answers. (#42844, #42852, #43442)

    • Plus and Team users receive an earlier warning when less than half their allowance remains in the approximate five-hour window. (#42142)

    Bug fixes

    • The TUI reconnects after an external app-server disconnect while preserving drafts and transcripts; uncertain or queued submissions pause for review. (#41911, #41916, #41918)
    • Full Access skips Guardian review for confirmation-only actions, while User approval skips background Guardian scoring and prewarming; sensitive checks and input requests remain unchanged. (#42147, #42256)
    • Guardian history survives compaction, restarts, and user forks, respects rollback, and isolates subagent history. (#41879, #42065)
    • Remembered MCP approvals are scoped to the selected app account, and relative MCP executable paths start more reliably on macOS. (#42133, #42117)

  • Browser extensions, site tools, and cloud sign-in

    • More browsers: Use the ChatGPT browser extension in Microsoft Edge, Brave, Opera, and Vivaldi, as well as Chrome. Set up your browser in Settings > Computer Use in the ChatGPT desktop app. All five support tab mentions and browser control; Opera doesn't support side chat.
    • Site tools (WebMCP): In the desktop app's built-in browser, ChatGPT Work and Codex can use tools provided by a website to work with the page. Use GPT-5.6 Sol or GPT-5.6 Terra and update to the latest desktop app. Site tools aren't available with GPT-5.6 Luna or in Enterprise or Edu workspaces.
    • Cloud browser sign-in: On eligible plans, ChatGPT Work on the web, iOS, and Android can ask you to sign in to a supported website through the cloud browser. Enter your details in the sign-in flow, not in the chat. Cloud browser sessions stay separate from your local browser. Website sign-in isn't available for Enterprise or Edu workspaces.

    Availability depends on rollout and workspace settings. Website-access and action-confirmation requirements still apply.

  • Trigger scheduled tasks from Gmail, Slack, and GitHub events

    ChatGPT scheduled tasks can now run when supported events occur in Gmail, Slack, or GitHub. Filter Gmail messages by sender or subject, watch selected Slack channels, or respond to pull request activity such as reviews, comments, commit updates, and merges.

    Event-triggered tasks are available in ChatGPT on the web and mobile for eligible plans. Connect the relevant app and approve its requested access before creating a task. The ChatGPT Slack app must be a member of each watched channel, and the connected GitHub app must have access to each watched repository.

    An event-triggered task can't also use a time-based schedule. When matching events arrive close together, ChatGPT may combine them in one run. Open Scheduled to review pending events or choose Run now.

    Learn how to trigger scheduled tasks from app events.

    New features

    • Apple Messages: Use the Apple Messages plugin in ChatGPT Work and Codex on macOS to read, search, draft, and send messages. Sends require approval by default. See the plugin guide.
    • Site co-editing: Where available, Site owners can invite active members of the same workspace as editors. Editors can read the live database and publish updates after the owner completes the first publish.
    • Editable Site URLs: Where available, owners can change a Site's ChatGPT-hosted address without creating another deployment. The old address redirects to the new one.
    • Computer History in Europe: Computer History is now available in the EEA, Switzerland, and the United Kingdom. It remains off by default and requires Memories; managed workspace administrators must enable access first.
    • Shared thread snapshots: Share a read-only snapshot of a local Codex thread from the ChatGPT desktop app for macOS. Review snapshots before sharing even though known secret patterns are redacted.
    • Unified pinned threads: Pinned chats now stay in sync between the ChatGPT desktop app and iOS.

  • GitLab support in Codex cloud (Beta)

    GitLab support is available in beta on all ChatGPT plans. Connect a GitLab project to Codex cloud, create an environment, start tasks from issues or merge requests with @codex, and request one-off or automatic merge request reviews.

    The integration runs in Codex cloud. A managed workspace administrator can disable the connector. GitLab-triggered activity requires permission to configure the applicable webhook. GitLab Self-Managed and GitLab Dedicated connections require workspace administrator setup, and webhook activity requires GitLab 19.0 or later. Codex cannot complete a review when GitLab omits a collapsed or oversize diff.

    Learn more in GitLab integration.

  • Computer History

    Computer History is an opt-in feature in the ChatGPT desktop app on macOS that turns activity across apps and websites into memories and a timeline that ChatGPT and Codex can use. Choose which apps and websites contribute, pause collection, and review or delete your history at any time.

    Computer History is available to ChatGPT Pro, Business, and Enterprise users. Business and Enterprise administrators must enable access before workspace members can turn it on. Initial availability excludes the European Economic Area (EEA), Switzerland, and the United Kingdom.

  • Introducing Daybreak Blue and Daybreak Red

    Daybreak now offers two access tiers for approved defenders: Daybreak Blue and Daybreak Red. Use them to move from security findings to validated fixes in explicitly authorized engagements.

    Start with Daybreak Blue for most defensive security work. It provides access to general-purpose models such as GPT-5.6 Sol for vulnerability discovery, secure code review, detection engineering, incident response, malware analysis, and patch validation.

    Daybreak Red provides separately approved access to purpose-trained models such as GPT-5.6 Cyber for authorized vulnerability reproduction, exploit validation, penetration testing, red teaming, and complex system analysis.

    Access requires approval through Trusted Access for Cyber and applies only to the approved identity, workspace or API organization and project, model, and product surface. Daybreak Red requires separate approval and provisioning; Daybreak Blue access doesn't grant access to Daybreak Red.

    Work in an isolated environment, define your engagement scope, use least-privilege permission profiles, and configure Auto-review for eligible actions before they cross the sandbox boundary.

  • GPT-5.4 and GPT-5.4 mini retire from Codex on August 31

    On August 31, 2026, GPT-5.4 and GPT-5.4 mini will no longer be available in Codex for users signed in with ChatGPT. GPT-5.4 and GPT-5.4 mini will remain available on the OpenAI API and in Codex sessions authenticated with an API key.

    Switch to their recommended replacements:

    • Replace gpt-5.4 with gpt-5.6-terra (GPT-5.6 Terra).

  • Sign in with ChatGPT (beta)

    Sign in with ChatGPT is beginning to roll out in beta across select plugins and partner sites, starting with Airtable, GitLab, HubSpot, Notion, Supabase, and Vercel.

    When you connect a supported plugin from the ChatGPT plugin directory, you can use Sign in with ChatGPT to create or link an account with that service in fewer steps. On participating partner sites, you can also select Sign in with ChatGPT to create or access your account.

    This makes it easier to start working with supported tools in ChatGPT and Codex.

    When you sign in, the partner receives only your name, email address, and profile picture, if available. You must still review and approve each plugin's requested access as a separate step.
