ChatGPT includes Chat and Work, plus Codex in the desktop app. Chat is for fast, conversational assistance and everyday questions. Work is an agent designed for longer, multi-step work and finished deliverables. Codex remains dedicated to software development and technical work.

Work follows the same usage structure as Codex. The Codex pricing page explains included usage and additional credits; its examples are based on coding tasks, so Work usage will vary by task.

Choose an experience

• Chat: Ask questions, search, brainstorm, or get quick conversational help.

• Work: Research a topic, analyze information, or create a document, spreadsheet, presentation, report, or Site.

• Codex: Write or debug code, run tests and commands, review changes, or work with a repository.

Where Work and Codex are available

Work is available on ChatGPT web and mobile for eligible paid plans. Work is also available in the ChatGPT desktop app when included for your plan and workspace.

Work is available for eligible ChatGPT Enterprise and Edu workspaces with Enterprise Key Management (EKM) enabled. Workspace settings and role-based access controls still determine member access.

Work on web and mobile runs in the cloud. In the desktop app, select ChatGPT from the top-left menu, then select Work from the toggle at the top of the page. Chat and Work chats appear together in Recents, where you can sort, filter, and pin chats. Your existing ChatGPT Projects appear under Projects. From a project, choose Chat to start a new chat, or choose Work to start a Work chat using the project’s context. When allowed by your plan and workspace, Work in the desktop app can also use local files and desktop apps with your permission.

Cloud Work chats sync across web, mobile, and desktop. Work chats started on web or mobile appear in the desktop app, and cloud Work chats started on desktop can be continued on web or mobile. When you start local chats, they stay on your computer. 

Codex remains a separate view in the ChatGPT desktop app. Select Codex from the top-left menu. Its workflows are unchanged, and its history remains separate from ChatGPT history. Codex can work with local folders, repositories, terminals, and developer tools. Codex is not selectable on web or mobile. You can access supported desktop Codex chats from the Remote tab in the ChatGPT mobile app, but those chats do not become web or mobile chat history.

Is Codex available on web or mobile?

Codex is not selectable on web or mobile. You can access supported desktop Codex chats from the Remote tab in the ChatGPT mobile app. Remote access does not add those chats to your web or mobile chat history.
