ChatGPT

The Work Operating System You Can Talk To

ChatGPT now separates work by intent: Chat for questions and conversation, Work for longer tasks and finished deliverables, and Codex for software development. The shift is from an assistant that answers to a work environment that can research, create, steer, schedule and execute.

1 / Meet ChatGPT

Three modes for three different kinds of work

Chat handles questions and conversation. Work carries longer jobs into finished deliverables. Codex owns software development. They share context and tools, but each mode sets a different expectation for autonomy and output. On July 16, 2026 the desktop app was reorganized around that split: the top-left menu is now a global switcher between ChatGPT and Codex, and a toggle inside ChatGPT moves between Chat and Work.

Personality

Fast, adaptive and willing to start

ChatGPT is unusually good at turning an incomplete request into momentum. It can ask questions, propose a structure and make a first version quickly.

  • Broad multimodal capability
  • Strong iterative conversation
  • Useful from blank page to final artifact
Deploy it for

Cross-functional knowledge work

Research, planning, writing, image creation, file analysis, data explanation and coding can remain connected inside one working thread.

  • Executive briefs and decisions
  • Research with current sources
  • From prototype to production code
Choose it when

The work may change shape

Start in Chat to clarify, move into Work for the finished artifact, or hand the software outcome to Codex without rebuilding the whole brief.

  • The brief is still ambiguous
  • Several output types may be needed
  • The work benefits from shared context

Choose the mode by the outcome

The most important new control is not the model. It is the working mode.

Work
Longer tasks and finished deliverables

Use Work when you can name the outcome and want ChatGPT to research, analyze, create the artifact, show progress and ask for approval at consequential moments.

  • Documents, spreadsheets, presentations and reports
  • Sites and reusable work products
  • Steer, redirect and approve while it works

From vague request to finished work

The important shift is treating the conversation as a working environment, not a series of isolated prompts.

Frame
Turn the request into a deliverable

Ask ChatGPT to identify the audience, decision, constraints and evidence required before it begins production.

  • Name what “done” looks like
  • Surface missing inputs
  • Agree the review points
2 / ChatGPT Work

Work turns a conversation into an accountable production run

Launched July 9, 2026 and powered by GPT-5.6, Work is the mode for longer tasks that should end in something usable. It can research and analyze, use connected apps and files, build finished artifacts, show progress, accept redirection and pause for important approvals. OpenAI describes it as staying with a project for hours.

Outcome mode

Research and analysis

Give Work the decision or finished state, not just a question. It can gather current evidence, inspect files and keep a longer analytical process moving.

  • Use connected apps and uploaded files
  • Track progress instead of waiting blindly
  • Require source and uncertainty reporting
Artifact mode

Finished deliverables

Work can create the actual business object: a document, spreadsheet, presentation, report or other reusable output.

  • Specify audience and acceptance criteria
  • Review the artifact, not only the summary
  • Keep important calculations visible
Publishable work

Sites public beta

Sites extends the output from a static answer into dashboards, trackers, launch calendars, prototypes, internal portals and reports. The help article now describes the public beta as covering all plans except Free and Go, which brings Plus and Business into scope alongside the original four.

  • Not available in the EEA, Switzerland or the United Kingdom
  • The help article carries no date, so read the wider eligibility as current state rather than a dated change
  • Treat live information and access as product requirements
Persistent work

Scheduled Tasks

A task can run once, repeat on a schedule, respond to a trigger or monitor something over time.

  • Define the trigger precisely
  • Name the notification and escalation path
  • Recheck permissions for recurring work
Human control

Progress and steering

You can follow the work, answer questions and change direction without restarting the task or losing the developing context.

  • Set review points early
  • Redirect when assumptions change
  • Do not mistake visible activity for quality
Consequential actions

Approval moments

Work can ask for approval before important actions, making authority boundaries a designed part of the workflow.

  • State which actions always require approval
  • Use least-privilege access
  • Inspect the resulting external state
Desktop reach

Local files, apps and browser

On desktop, Work can use local files and applications alongside a built-in browser. Computer Use lets it click, type and move files across your apps in the background. Since July 16 a unified Recents list merges Chat and Work, and Projects are available on desktop.

  • Cloud Work conversations sync across web, mobile and desktop
  • Local conversations stay local, so plan for where the record lives
  • Grant only the context the task needs and review external transmissions
Extensibility

Unified plugin directory

Plugins connect ChatGPT to Slack, Teams, Drive, SharePoint, email, calendars, CRMs and internal tools. Type “@” to direct ChatGPT at a specific app; the new directory brings plugins into one place.

  • Standardize repeatable workflows
  • Review plugin authority and data access
  • Prefer governed organizational plugins
Governance

Auto-review of important actions

Auto-review uses OpenAI’s most advanced models to review consequential actions involving connected tools and APIs before they happen. OpenAI reports that in its own adversarial red teaming the feature blocked 100% of attempts to extract protected data.

  • Vendor red-team result — not an independent audit
  • A control, not a guarantee
  • Compliance API gives oversight at scale
  • Admins set spend and access limits
Rollout

Who has Work today

The July 9 release note names the first wave as Pro, Pro Lite, Enterprise and Edu, with Plus and Business following within days. Enterprise and Edu received a two-week preview, off by default, with an admin opt-out before automatic enablement. No dated article yet confirms that the Plus and Business rollout completed; the July 21 small business article says Work is available to small businesses today, which is indirect evidence that Business landed. Treat the first wave as dated fact and the rest as in progress, and check your own plan picker.

  • Do not confuse the Work rollout with the Sites rollout
  • The desktop app exposes the Chat, Work and Codex surfaces on every plan, including Free; which plans are entitled to use Work is the separate question above
  • The old desktop app is renamed ChatGPT Classic

The Work contract

A good Work task has a visible control loop between delegation and delivery.

Outcome
Define the finished state

Name the artifact, audience, decision, deadline, source boundaries and quality bar before the task expands.

  • Ask for the usable object
  • Include examples and house style
  • State what must not happen
Executive deliverable
Use Work to produce the finished leadership briefing, not just an outline. Research current primary sources, build the supporting analysis and charts, create the presentation, and pause for approval before any publication or sharing.
Scheduled monitor
After completing one verified manual run, schedule this monitor for every weekday. Notify me only when the threshold is crossed, include the evidence and timestamp, and never take an external action without approval.
Site build
Create an internal launch Site with the live plan, owners, milestones, decisions, risks and source documents. Use our brand system and make every status field auditable.
3 / Models & Modes

Pick the working mode first, then the tier, then the effort

GPT-5.6 reached general availability on July 9, 2026 across ChatGPT, Codex and the API, following a limited preview that began June 26. The generation number is 5.6; Sol, Terra and Luna are durable capability tiers that advance on their own cadence. Effort runs on a standard low-to-xhigh ladder, with max and ultra sitting above it: max buys more reasoning time, and ultra runs parallel agents. On July 30, 2026 OpenAI cut Luna by 80% and Terra by 20%, left Sol untouched and gave Sol a Fast mode.

GPT-5.6 Sol Flagship

OpenAI describes it as its most capable model and reports state-of-the-art results across coding, knowledge work, cybersecurity and science. Stronger computer use and design judgment let it inspect and refine a rendered result, not just generate it. It is the one tier the July 30, 2026 price cuts did not touch: OpenAI states that Sol pricing remains unchanged.

  • $5 input / $30 output per 1M tokens — unchanged on July 30, 2026
  • Sol Pro available to Pro and Enterprise in Chat
  • Gains a Fast mode: OpenAI claims up to 2.5x faster speeds than Standard processing at twice the price, with no change in intelligence
  • OpenAI reports fewer tokens than competing frontier models — verify on your own tasks

GPT-5.6 Terra Balanced

A lower-cost tier that OpenAI positions as competitive with GPT-5.5. This is the model Free and Go users receive inside Work and Codex. Its price fell 20% on July 30, 2026.

  • $2 input / $12 output per 1M tokens, down from $2.50 / $15
  • Default tier for Free and Go in Work
  • Strong everyday cost-to-quality ratio

GPT-5.6 Luna Most efficient

The fastest and most affordable tier, and the biggest mover on July 30, 2026: OpenAI cut it by 80%, a 5x reduction on input. OpenAI reports it outperforms Claude Opus 4.8 on the Artificial Analysis Coding Agent Index at roughly a quarter of the estimated cost — that comparison was published on July 9, before the cut, so the cost side of it is now stronger still.

  • $0.20 input / $1.20 output per 1M tokens, down from $1 / $6
  • Best for high-volume, low-stakes work
  • Vendor benchmark — verify on your own tasks

Programmatic Tool Calling

In the Responses API, GPT-5.6 can write and run lightweight in-memory programs that coordinate tools and filter intermediate results, cutting round trips. It is Zero Data Retention compatible.

  • Fewer tokens on tool-heavy tasks
  • Less step-by-step scripting
  • Multi-agent available in beta

Prompt caching changes

GPT-5.6 introduces explicit cache breakpoints and a 30-minute minimum cache life. Note the billing change: cache writes now cost 1.25x the uncached input rate.

  • Cache reads keep the 90% discount
  • Writes are no longer free
  • Model your caching before you scale

Where Codex lives now

The Codex app became the new ChatGPT desktop app, with inline diff editing, pull-request review in a side panel and multi-repository projects. Since the July 16 reorganization, Codex sits behind the global top-left switcher opposite ChatGPT. The previous desktop app becomes ChatGPT Classic.

  • Still unavailable on web and mobile; view desktop Codex chats from the mobile Remote tab
  • Atlas browser is being sunset
  • Chrome extension moves to the sidebar

Choose reasoning effort by consequence

The right setting is the least expensive one that reliably absorbs the cost of being wrong. Effort is not correctness. The ladder below uses the API, Codex and ChatGPT Work labels; the consumer picker in ChatGPT is documented with a different set.

Efficient defaultParallel agents
Medium
Everyday decisions and analysis

The efficient default. Several constraints matter, but the task does not need a long research or reasoning process. In Chat this is the floor at which Sol becomes available.

  • Balanced speed and depth
  • State the decision criteria explicitly
  • Sufficient for most professional work
4 / The Platform

Chat, Work and Codex share a wider work platform

What surface should you use?

Pick the result, not the most impressive feature.

I need an answer
Use Instant conversation

Ask directly, add constraints in follow-ups and stop when the answer is sufficient.

  • Do not over-engineer routine work
  • Use the web if current facts matter
  • Save higher effort for real complexity
5 / Agentic Work

Work and Codex make delegation a first-class product behavior

Work is the general business agent; Codex is the software agent. Both are useful when they can plan, use tools, observe results and keep going—making outcome definition, approval points and authority boundaries more important than prompt cleverness.

The reliable agent loop

Each stage needs a different kind of human involvement.

Outcome
Name the finished state

Specify the usable artifact or system change, the audience and the evidence that proves the work is complete.

  • Avoid topic-only prompts
  • State non-negotiable constraints
  • Include acceptance tests
Research agent
Produce a decision-ready market brief using current primary sources. Compare publication date and event date, link every material claim, and mark all inference explicitly.
Coding agent
Implement the feature in this repository. Inspect the architecture first, update every affected test and document, run the relevant checks, and stop only when they pass or a blocker is proven.
Document agent
Turn these notes, files and data into the finished client report. Use our structure and voice, create the tables needed to support the argument, and run a final source-coverage audit.
Critical handoff
Before finishing, report: what you changed, what evidence confirms it worked, what you did not verify, and the single most important human review step.
6 / Behavior Playbook

Eight habits that make ChatGPT a stronger colleague

The biggest gains come from changing how work is delegated and reviewed, not from adding decorative prompt syntax.

01

Start with the deliverable

Ask for the thing you will use, not a generic answer about the topic.

02

Give decision criteria

Explain how alternatives should be judged instead of asking for an undefined “best.”

03

Use current sources deliberately

Request first-party material and open the claims that matter.

04

Separate making from judging

Run a dedicated review pass after the creative or analytical pass.

05

Choose mode, then effort

Chat for dialogue, Work for deliverables, Codex for software—then spend deeper reasoning only where consequence warrants it.

06

Keep the thread alive

Build from research to artifact without throwing away the context established earlier.

07

Make uncertainty visible

Ask what the evidence cannot support and what would change the conclusion.

08

Verify the external result

A tool action, file or code change must be checked in the system where it matters.

Decision memo
Create a two-page recommendation for leadership. Show the trade-offs, include the strongest argument against your recommendation, and end with the exact decision required.
Source discipline
Verify this against current first-party sources. Link every material claim and clearly separate vendor fact, third-party observation and your inference.
Anti-sycophancy
Assume my preferred answer may be wrong. Find the strongest disconfirming evidence and tell me what a skeptical expert would challenge first.
Coverage audit
Map every supplied file to the claims in your output. Identify any document or section you did not use and explain why.
7 / Watch Outs

Fluent, connected and agentic still does not mean verified

ChatGPT’s breadth creates a particular risk: one polished conversation can mix solid source work, model inference and tool actions so smoothly that the boundary becomes invisible.

Plausible citations

A link can be real while failing to support the claim placed beside it. Open the material sources.

Sycophancy

The model may inherit your framing and optimize for agreement. Request the strongest contrary case.

Long-thread drift

Instructions and definitions can soften across long work. Restate the acceptance criteria at major transitions.

Tool-action ambiguity

A described action is not proof of a completed action. Inspect the external state or artifact.

Memory boundaries

Review what is stored, which workspace is active and whether personal context belongs in managed work.

Mode and plan variation

Work, Sites, model controls and publishing differ across plans, regions and workspace policy.

Regional and eligibility limits

Sites is unavailable in the EEA, Switzerland and the United Kingdom. Health is United States only, web and iOS, 18 and over, and is not available in Codex. Presence is limited to eligible enterprise customers. Confirm availability before you plan a rollout around a feature.

Scheduled authority

Recurring tasks can outlive the assumptions and permissions of the first run. Give every schedule an owner, failure path and review date.

Image truth

Generated visuals may contain inaccurate text, products, interfaces or implied evidence.

Reasoning theater

Longer reasoning is not automatically correct. Judge the evidence and the result, not the apparent effort.

The September 24 shutdowns

The Sora 2 model line and the Videos API both go dark on September 24, 2026 with no stated replacement. If video generation sits anywhere in a workflow, that is a rebuild, not a version bump.

8 / Sources

First-party evidence behind this guide

OpenAI ships quickly, and its own help center lags its own launches. Every dated claim above is anchored to a dated article rather than to a rolling index. Where OpenAI publishes only an undated support page, as it does for Sites, plugins, scheduled tasks and the consumer effort picker, that is stated inline rather than dressed up as a dated source. One entry below is a living reference table rather than an article: the deprecations page, which is the only authoritative record of shutdown dates, carries the date it was read. The July 28 transcription models were announced through the changelog alone and have no article to cite, which is said inline instead. And note that on August 3, 2026 OpenAI’s own marketing pricing page still showed pre-July 30 rates while its developer documentation showed the new ones — documentation lag is not only a problem between vendors.
