OpenAI has introduced ChatGPT Work, an autonomous task agent powered by the new GPT-5.6 model family, and simultaneously confirmed it will discontinue its Atlas AI browser on 9 August 2026, less than nine months after its launch. The twin moves reshape the company’s product landscape: a standalone browser is being absorbed into a unified desktop application, while a new agentic tool aims to automate complex, multi-hour office projects with minimal human intervention.

ChatGPT Work can ingest context from connected services—Gmail, Google Drive, Slack, Microsoft Teams, and calendars—and independently break large tasks into steps, producing finished documents, spreadsheets, presentations, reports, and even interactive websites. A built-in desktop browser, supporting multiple tabs, password management, and passkey authentication, lets the agent browse the web, log into accounts, and download files on a user’s behalf. A cloud-based browser running on OpenAI’s servers extends this capability, allowing agents to complete tasks while users monitor progress via screenshots. The platform also integrates more than 1,400 plugins and a Plan mode that proposes a step-by-step approach for user approval before execution. The tool is available initially to Pro, Enterprise, and Edu customers, with Plus and Business subscribers to follow.

The Atlas shutdown is part of a broader consolidation directed by OpenAI’s head of applications, Fidji Simo, who earlier asked teams to reduce work on secondary projects. The company had already closed its AI video-generation tool Sora. Atlas, built on Google’s Chromium engine—a detail not highlighted at its October 2025 launch—drew criticism in early reviews for poor search relevance and limited source linking. Its capabilities are now migrating to the ChatGPT desktop app and a new Chrome extension, which can summarise pages and initiate longer tasks. The existing Codex desktop app is also being folded into the same application, creating what the company describes as a single “super app” for chat, coding, and agentic work.

Viewed from North America, the launch intensifies the race with Anthropic, whose Claude Work agent already automates tasks in law, sales, marketing, and data analysis. The earlier debut of Claude Work triggered sharp declines in the shares of software and professional-services firms in the United States and Europe, reflecting market anxiety about AI’s impact on the data-analytics industry. Analysts in London note that OpenAI’s move to embed agentic capabilities directly into a widely used chatbot could accelerate enterprise adoption, while observers in East Asia point to the integration of Codex and the browser as a signal that the company is prioritising a streamlined developer and business-user experience over standalone experimental products.

OpenAI is rolling out the new desktop application globally for Windows and macOS, with web and mobile access expanding in the coming days. The Atlas end-of-life date of 9 August 2026 provides a clear milestone for users to transition. The next factual marker will be the expansion of ChatGPT Work to Plus and Business tiers, which the company has said will happen later, though no specific date has been announced.
