OpenAI just flipped the competitive script on the productivity agent race. Two days after Claude Cowork went to web and mobile, OpenAI launched ChatGPT Work, a new agent in ChatGPT that can take action across your apps and files, stay with a project for hours, and turn a goal into finished work.
It’s the product of bundling Codex, GPT-5.6, and a unified plugins system into the ChatGPT you already use. And it changes what ChatGPT can do by an order of magnitude.
What ChatGPT Work Actually Does
ChatGPT Work is not a new app. It’s a new agent mode inside ChatGPT, available on web, mobile, and desktop. You select Work instead of Chat and describe the outcome you want. The agent then gathers information across your connected apps (Slack, Teams, Google Drive, SharePoint, email, CRMs, calendars) and creates finished materials.
Sheets. Slides. Docs. Even hosted web apps, which OpenAI calls Sites.
The agent can run for hours on a single task, breaking it into steps and completing them independently. It can check in with you, ask questions, or push forward based on your initial direction. And with GPT-5.6 Sol under the hood, launching alongside ChatGPT Work today, it has reasoning depth to actually pull off multi-step work without falling apart.
The Codex Angle Everyone’s Missing
This is the sleeper part of the announcement. OpenAI has been running Codex as a separate app for developers. It has 5 million weekly users. More than 1 million of those users already use Codex for work outside software development: writing, research, project management.
ChatGPT Work absorbs Codex’s capabilities into the main ChatGPT experience. The Codex app is merging into the new ChatGPT desktop app. Developers can still set Codex as their default view and keep the Codex icon. But for everyone else, Work is now the default mode for productivity.
That 5 million weekly user base becomes ChatGPT Work’s adoption runway overnight. That is a distribution advantage no competitor has.
A Direct Answer to Claude Cowork
The timing is not subtle. I covered Claude Cowork’s web and mobile launch on July 7th. Two days later, OpenAI drops this.
Claude Cowork lets you hand off tasks to Claude across web, mobile, and desktop. Similar pitch, different execution. Claude uses artifacts and projects as its workspace. ChatGPT Work uses plugins, connected apps, and a new Sites feature for deliverables.
Both are chasing the same insight: single-turn chat is not where the value is. The value is in agents that stay with a task for hours, coordinate across tools, and deliver finished work instead of answers.
OpenAI’s bet is that bundling this with the most popular AI chat product on earth is enough to win. Given that ChatGPT already has hundreds of millions of users, it’s not a bad bet.
Sites: Hosted Web Apps Inside ChatGPT
One feature in ChatGPT Work that Cowork doesn’t directly answer: Sites. In public beta, Sites lets you turn work or ideas into an interactive web app or site hosted by OpenAI. Live dashboards, project trackers, internal portals, interactive reports. Created from a ChatGPT Work conversation and shareable via URL.
The ability to generate and host functional web apps from natural language is the kind of feature that sounds like a demo trick until you need a quick dashboard and realize you just saved three hours.
Scheduled Tasks for Recurring Work
ChatGPT Work can also run on a schedule. Ask it to review new Slack messages each Monday and refresh a meeting agenda, or check a dashboard each morning and summarize what changed, or update a presentation when new feedback arrives by email.
This is OpenAI’s version of the background agent pattern that Google and Anthropic have been shipping. The difference is ChatGPT Work can use your connected apps as both source and destination: it can read from Slack and write back to Google Slides in the same scheduled run.
Availability and Pricing
ChatGPT Work starts rolling out today on web and mobile for Pro, Enterprise, and Edu users. Plus and Business users get it in the coming days. On the ChatGPT desktop app (now available globally for Mac and Windows), Chat, Work, and Codex are available on every plan, including Free.
Usage works differently from regular chat. Complex tasks consume more of your plan’s included usage, following the same structure as Codex. Enterprise admins get spend controls, workspace-level defaults, group limits, and individual overrides.
The existing ChatGPT desktop app is being renamed ChatGPT Classic. The Codex app becomes the new ChatGPT desktop app. Developers can keep the Codex icon and default view. Users who want quick questions without the agent layer can use the new Quick chat button.
Atlas, OpenAI’s standalone browser, is being sunset. The lessons from Atlas are being folded into ChatGPT’s built-in desktop browser and Chrome extension sidebar.
What This Means
Two days ago, Claude Cowork was the most interesting productivity agent launch of the year. Today it has direct competition from the company with the largest installed base in AI.
ChatGPT Work is not a feature update. It is OpenAI pivoting ChatGPT from a question-answering product to a work-execution platform. The Codex merger, the plugins directory, Sites, Scheduled Tasks, and the GPT-5.6 backbone all point in the same direction: OpenAI wants ChatGPT to be where work happens, not just where answers come from.
Whether ChatGPT Work delivers on the multi-hour promise is something I will test in the coming days. But the positioning is clear. OpenAI is no longer building a chatbot. It is building an operating system for knowledge work.
