What Are ChatGPT Chat, Work and Codex in 2026?
ChatGPT is now three experiences rather than one. Chat is for fast, conversational assistance and everyday questions. Work is an agent designed for longer, multi-step work and finished deliverables. Codex stays dedicated to software development and technical work. On the ChatGPT desktop app all three are reachable; on web and mobile you get Chat and Work, and Codex is not selectable.
The distinction that matters commercially is between Chat and Work. Chat answers. Work produces: OpenAI describes it as the place to research a topic, analyse information, or create a document, spreadsheet, presentation, report or Site. Work also runs once, repeats on a schedule or a trigger, and can monitor for changes, which is what turns it from an assistant into something closer to a team member with a task list.
Explain It Like I Am Five
Think of a shop with three counters. At the first counter you ask a quick question and get a quick answer, then you leave. That is Chat. At the second counter you hand over a job with all your papers and come back later to collect a finished folder: a report, a slide deck, a spreadsheet. That is Work. At the third counter there is a specialist who only fixes machines, with all the right tools on the bench. That is Codex. Same shop, same sign above the door, three counters for three different kinds of asking. The mistake most people make is queueing at the first counter and wondering why nobody hands them a finished folder.
| Experience | What OpenAI says it is for | Where it runs in 2026 |
|---|---|---|
| Chat | Questions, search, brainstorming, quick conversational help | Web, mobile, desktop. Available in every configuration. |
| Work | Research, analysis, and creating a document, spreadsheet, presentation, report or Site | Web and mobile on eligible paid plans, plus desktop when included for your plan and workspace. |
| Codex | Writing or debugging code, running tests and commands, reviewing changes, working with a repository | Desktop app only as a selectable experience. Not selectable on web or mobile. |
| Voice | Talking naturally with Work, or with Work and Codex on desktop, including starting tasks | Work on web, iOS and Android; Work and Codex in the desktop app on macOS and Windows. |
Why Does the Chat and Work Split Matter for Business Teams in 2026?
Because the two experiences have different economics, different permissions and different outputs, and a team that treats them as one product will get billed for one while asking for the other. Work follows the same usage structure as Codex rather than the Chat structure, so it draws on an agentic allowance. OpenAI notes that the Codex pricing page explains included usage and additional credits, and that its examples are based on coding tasks, so Work usage will vary by task.
- Different deliverable: Chat returns a reply you copy somewhere. Work returns the artefact itself, including spreadsheets, presentations and Sites.
- Different allowance: Work consumes your Work and Codex allowance. Heavy Work use is not the same budget line as heavy Chat use.
- Different admin surface: Work Cloud, Work Local and Codex Local are separate workspace permissions. Chat stays available in every configuration.
- Different model menu: GPT-6 Sol and GPT-6 Luna are models for Work and Codex and are not available in regular ChatGPT conversations.
- Different default: the starting model for Work and Codex is configured separately from the Chat default, so changing one does not change the other.
Which Models Run in Work and Codex in 2026?
Work and Codex have their own model line-up. GPT-6 Sol and GPT-6 Luna are Work and Codex models that OpenAI states are not available in regular ChatGPT conversations. GPT-6 Astra is available through both Chat and the agentic experiences depending on plan, and GPT-6 Pro, powered by Astra, is the ChatGPT-side offering for higher tiers. Availability depends on your plan, your workspace settings and rollout access.
| Plan | What OpenAI published for 2026 |
|---|---|
| Plus | Includes GPT-6 Astra in ChatGPT Work and Codex. Limited Astra usage, with optional credits for more afterwards. |
| Pro 100 USD and Pro 200 USD | GPT-6 Pro, powered by GPT-6 Astra, is available in ChatGPT. Both plans can use their full existing allowance for Astra. |
| Business Standard | Limited Astra usage, with optional credits for additional usage. |
| Business Premium | Seats can use their full existing allowance for Astra. |
| Enterprise | GPT-6 Pro available, and access also depends on the workspace's model-access permissions. |
Two mechanics are worth knowing before anyone plans a budget. First, the model picker offers Default or a specific model: Default combines models and reasoning levels along one slider, while selecting a model lets you choose from that model's own reasoning levels. The Codex CLI does not use a slider, and Codex keeps the model you selected manually. Second, OpenAI states plainly that Astra can use your allowance faster than GPT-5.6 Sol, and that how much you get depends on the task, input and output size, reasoning settings and Fast mode.
Astra requires Codex CLI version 0.153.0 or newer, and the latest ChatGPT Desktop app. OpenAI's guidance is specific: if Astra does not appear in Chat, Work or Codex on desktop, use Menu then Check for Updates, even if the app recently updated automatically or showed an update icon in the sidebar. Most "we do not have access" reports are a stale client rather than a plan problem.
How Does Billing Work Across Work, Codex and Voice in 2026?
Work draws on the same agentic pool as Codex, and how you signed in decides which meter runs. Signing in to Codex with your ChatGPT account uses your ChatGPT plan's usage and billing. Using your own API key uses API pricing instead. For usage paid in credits, OpenAI points to the personal-plan credit pricing, the Business, Enterprise and Edu credit rate card, and for Enterprise customers billed in US dollars, their Enterprise USD rate card and agreement.
Voice is metered differently depending on surface. On web and mobile, Voice in Work uses minutes from your daily Voice allowance, and OpenAI states that Work tasks follow the same pricing whether you start them by speaking or typing. In the desktop app, connected Voice time is metered separately where flexible pricing applies, while tasks started through Voice draw from the same shared agentic usage and credit pool as Work and Codex.
Where Are Work and Codex Available in 2026?
Work is available on ChatGPT web and mobile for eligible paid plans, and in the desktop app when included for your plan and workspace. For ChatGPT Enterprise and Edu, Work is available for eligible workspaces with Enterprise Key Management enabled, and in those workspaces it is enabled by default for members on the default workspace role unless an owner or admin turns it off. Workspace settings and role-based access controls still determine each member's access.
Codex stays a separate view in the desktop app, reached by selecting Codex from the top-left menu. Its workflows are unchanged and its history stays separate from ChatGPT history. Codex can work with local folders, repositories, terminals and developer tools. It is not selectable on web or mobile, although supported desktop Codex chats can be reached from the Remote tab in the mobile app, and those chats do not become web or mobile chat history.
Cloud, local, and what syncs
- Web and mobile Work runs in the cloud. It cannot directly access files on your computer.
- Desktop Work can use local files and desktop apps with your permission, when your plan and workspace allow it. Open a local folder or project and grant access only to the files the task needs.
- Cloud Work chats sync across web, mobile and desktop. A cloud Work chat started on desktop can be continued on web or mobile, and the other way round.
- Local chats run on your computer, but OpenAI states that messages and task context may be stored in the cloud even when the work runs locally. That sentence belongs in any data review you run before rollout.
- Chat and Work chats appear together in Recents on desktop, where you can filter to all chats or only Chat or Work, and sort or pin them. Existing ChatGPT Projects appear under Projects.
How Do Workspace Admins Control Work and Codex in 2026?
Access is managed per role, and the controls are more granular than a single on switch. Workspace owners and admins manage Work for the default workspace role and for custom roles under Workspace settings, then Permissions and roles. Chat remains available in every configuration, and when Work or Codex Local is off for a member's role, that member can see the product is unavailable and request access from an admin.
| Control | What it does in 2026 | Rollout note for admins |
|---|---|---|
| Work Cloud | Members can start new cloud tasks and view existing cloud tasks across supported web, mobile and desktop surfaces. | The broadest grant. Start here for most business teams. |
| Work Local | Enabled without Work Cloud, members can work locally in the desktop app but cannot start cloud tasks. | Useful where data must stay on the device, with the cloud-context caveat above. |
| Codex Local | Controlled separately from Work. | Changing Work Local or Work Cloud does not change Codex Local access. |
| Browser use and network access | Separate controls continue to apply where supported. | Review these alongside Work, not after. |
| Workspace settings, Models | Sets a starting model, reasoning level, speed, Fast Mode availability and new-chat behaviour for Work and Codex. | Chat has its own separate starting default. Role overrides are evaluated separately for Chat and for Work and Codex. |
One rule prevents a common misunderstanding: a starting default does not grant access to a model or feature that is unavailable to the member's role. Setting a default is not the same as granting permission, so if a team reports that the configured model is not appearing, check the role first.
How Do You Start a Task in Work or Codex in 2026?
The flow is short, and the quality of the result depends far more on what you hand over than on where you click. OpenAI's own guidance is to describe the outcome you want and add any files, constraints and review criteria ChatGPT should use.
On the desktop app
- Open the ChatGPT desktop app and sign in.
- Select ChatGPT or Codex from the top-left menu.
- If you selected ChatGPT, choose Chat or Work from the toggle at the top of the page.
- Start a new chat or open an existing project. From a project, choose Chat for a new chat or Work to start a Work chat using the project's context. In Work or Codex you can also open a local folder.
- To use Voice, select the Voice control, allow the required permissions, and begin speaking.
- Describe the outcome you want, with files, constraints and review criteria.
- Review the result, then ask for changes or follow-up work in the same chat.
On web or mobile
- Open ChatGPT and select Work.
- Start a new chat or open an existing project.
- Add the files and context to be used, then describe the task or deliverable you want completed.
- To work by speaking, select the Voice control in Work and start a Live conversation, then follow the written responses and results in the chat.
A project keeps related chats, files and instructions together, which is the closest thing to a retainer folder inside the product. While a task runs you can review progress, answer questions, change direction and approve important actions. If a task is still running when you end a voice call, Work can continue it in text.
How Does Voice Change the Way Teams Use Work in 2026?
Voice adds a live spoken interface to Work on web and mobile, and to Work and Codex in the desktop app on macOS and Windows. You can speak, interrupt naturally, and use the tools and permissions available to the selected experience. You can also ask Voice to start or coordinate tasks, which makes it a way to hand over work rather than just a way to ask questions.
Three limits matter in practice. Only one Voice conversation can run at a time. In managed workspaces, Voice in Work requires both Voice access and Work access. And on web and mobile, if an action needs your approval you must review and approve or decline it using the on-screen controls, because spoken approval is not supported. Desktop computer context may additionally require Screen and Audio Recording and Accessibility permissions.
How Should Marketing and Growth Teams Use Work in 2026?
Put Work on the jobs that end in a file somebody opens, and keep Chat for thinking out loud. The deliverables OpenAI names, documents, spreadsheets, presentations, reports and Sites, are the exact artefacts a marketing team produces weekly, and the ability to attach files, constraints and review criteria up front is what separates a usable first draft from a rewrite.
| Marketing workflow | Experience to use in 2026 | Human checkpoint |
|---|---|---|
| Monthly performance report from exported data | Work, with the export attached and the report format as review criteria | Check every figure against the source platform. |
| Competitor and category research brief | Work, in a project so sources accumulate | Verify claims and citations before they reach a client. |
| Client-ready deck from an approved brief | Work, with the house template attached | Brand, claims and numbers review. |
| Campaign microsite or landing test | Work for a Site, or Codex if it belongs in your repository | Tracking, consent and compliance review before traffic. |
| Quick headline variants or a subject-line rewrite | Chat. It is faster and does not spend the agentic allowance. | Normal editorial judgement. |
| Analytics scripts, tag fixes, internal tooling | Codex, with the repository open | Code review and staged deploy. |
| Recurring monitoring and inbox or channel triage | Work with Scheduled Tasks and event triggers | See our event-triggered tasks guide. |
One habit is worth building in 2026: write the review criteria before the prompt. Work is designed to produce a finished deliverable, and a deliverable needs a definition of done. Attaching the template, the tone rules and the list of checks you will apply turns a generic output into something closer to house style on the first pass, which is where the time saving actually comes from.
What Are the Common Mistakes With Work and Codex in 2026?
- Assuming Work is Chat with a new label. It uses a different allowance, has its own admin permissions and its own model list.
- Blaming plan access for a stale client. Astra needs Codex CLI 0.153.0 or newer and the latest desktop app. Check for updates manually first.
- Expecting Codex on the web. It is not selectable on web or mobile. The mobile Remote tab reaches supported desktop chats only.
- Assuming local means private. OpenAI states messages and task context may be stored in the cloud even when work runs locally.
- Setting a workspace default and calling it access. A starting default does not grant a model or feature the member's role cannot use.
- Running everything on the heaviest setting. Astra can consume the allowance faster than GPT-5.6 Sol, and reasoning level and Fast mode both move that number.
- Sending a one-line brief to an agent. Work is built for outcomes, files, constraints and review criteria. A vague brief wastes a bigger unit of usage than a vague Chat message.
Key Takeaways for 2026
ChatGPT in 2026 is a three-counter product, and the operational work for a business is deciding which counter each job belongs at and who on the team is allowed to walk up to it.
- Chat for quick answers, Work for finished deliverables, Codex for software, Voice as a spoken way into Work and desktop Codex.
- Work follows the Codex usage structure, not the Chat one, and OpenAI notes the Codex pricing examples are coding-based so Work usage varies by task.
- GPT-6 Sol and GPT-6 Luna are Work and Codex models unavailable in regular ChatGPT conversations. Astra spans plans, with GPT-6 Pro on Pro, Business and Enterprise.
- Astra requires Codex CLI 0.153.0 or newer and an up-to-date desktop app.
- Work Cloud, Work Local and Codex Local are separate role permissions, and Chat stays available in every configuration.
- Web and mobile Work runs in the cloud; desktop Work can touch local files with permission, though context may still be stored in the cloud.
- Spoken approval is not supported on web and mobile. Approvals go through on-screen controls.
Distk helps growth teams across India and internationally decide which of these experiences each workflow belongs in, set the workspace permissions and defaults that match how the team actually works, and write the review criteria that make an agent's first draft usable. If ChatGPT Work is arriving in your workspace in 2026, that mapping is where we start.
