OpenAI unveils ChatGPT super-app with 'Work' agent and built-in browser, shuts down Atlas

OpenAI reframed ChatGPT from a chatbot into a desktop 'super-app' this week, bundling an autonomous agent named Work, an in-app browser, and a revamped interface into a single surface. The Work agent is designed to execute multi-step tasks — drafting, browsing, filling forms — while the built-in browser lets the assistant pull up docs, designs, and live sites without leaving the app. Inc. framed the launch bluntly: 'ChatGPT as you know it is dead.'

The most striking casualty is Atlas, OpenAI's standalone web browser, which it is shutting down barely nine months after launch. Folding browsing into ChatGPT signals OpenAI's bet that a single agentic surface beats a constellation of standalone products — and that users don't want to context-switch between an assistant and a browser.

Competitively, the move puts OpenAI head-to-head with Anthropic (whose Claude Code desktop just added an in-app browser too) and with agent-first tools from xAI and Google. The 'Work' agent directly targets enterprise productivity, where Microsoft Copilot and AWS agent platforms are entrenched.

Skeptics seized on the churn: killing Atlas so soon after launch became a case study in OpenAI's product volatility, and Axios described the broader GPT-5.6 lineup as a 'paradox of choice.' The open question is whether a monolithic super-app can stay coherent given how fast OpenAI ships — and whether features baked into ChatGPT survive longer than Atlas did.
