ChatGPT Work and Codex: September 28 – October 2, 2026 platform updates
Where your workspace has enabled these features, start a Work task on desktop and continue from your phone or browser, draft and share a Space Page with colleagues, or use scheduled Team Tasks for recurring project digests. Keep the connected computer online for steps that need it. IT teams can evaluate the Security Cloud research preview and review its findings and patches before creating a draft pull request.
What changed
Source summary
OpenAI's weekly update covers 28 September–2 October 2026; the source gives this range rather than an exact publication date. Codex Security Cloud is available in research preview on web and desktop: workspaces with access can install the plugin to scan connected GitHub repositories or monitor commits, then review findings, validation evidence and available patches before creating a draft pull request. Cross-device ChatGPT Work lets users start a new task on desktop and continue from web or mobile when the workspace enables Local computer access with Work Cloud; keep the connected computer online for steps that need it. ChatGPT Space offers collaborative Pages where available. Team Tasks run scheduled or event-triggered work through a team's service account and approved connections; Slack, Microsoft Teams and workspace connections depend on workspace and rollout. Developer updates include Plugin Extensions, webhook delivery from the draft MCP Events specification (requiring MCP 2.0; no polling or streaming), and the Browser Annotation API, available in supported versions of the desktop app's built-in browser, which lets website developers choose what people can select, attach relevant context and provide controls for previewing changes before sending feedback to ChatGPT. Previously covered model, dots and cloud-environment announcements are not counted as new capabilities here.
Why it matters to your work
Practical interpretation
Where your workspace has enabled these features, start a Work task on desktop and continue from your phone or browser, draft and share a Space Page with colleagues, or use scheduled Team Tasks for recurring project digests. Keep the connected computer online for steps that need it. IT teams can evaluate the Security Cloud research preview and review its findings and patches before creating a draft pull request.
When this could help
Useful when evaluating Codex Security Cloud, continuing desktop-started Work tasks from web or mobile, or collaborating on Space Pages where available. Team Tasks may suit recurring project digests through a team service account and approved connections. Separately, workspace admins can configure ChatGPT deployments and access in Slack or Microsoft Teams.
Use the workspace features described in this weekly update to review GitHub security findings, continue desktop-started Work tasks from web or mobile, collaborate on Space Pages, and run scheduled or event-triggered Team Tasks. Developers can also explore Plugin Extensions, MCP Events and the Browser Annotation API. Availability depends on the feature, workspace and rollout.

What to check
- Security Cloud is a research preview for scanning connected GitHub repositories or monitoring new commits. Review findings, validation evidence and available patches before creating a draft pull request. Source ↗
- Cross-device Work task continuity needs the connected computer to stay online for any step that depends on it; existing tasks keep whatever mode they already started in. Source ↗
- ChatGPT Space Pages and the Slack/Teams/Team Tasks workflows are rollout- and workspace-dependent, not guaranteed to be available to every account. Source ↗
- MCP Events requires MCP 2.0 and supports webhook delivery from the draft MCP Events specification; polling and streaming are not supported. Source ↗
- Plugin Extensions' Composer mentions are desktop-app only; Free and Go plan web extensions are still "coming soon". Source ↗
