- ChatGPT Atlas will stop working on August 9 after a brief wind-down period, and OpenAI warned the browser may no longer open, browse, or support agentic workflows after that date.
- OpenAI confirmed Atlas will not continue receiving security updates, and bookmarks will not transfer automatically — users must export them as HTML files before Sunday's deadline.
- OpenAI is redirecting users to the built-in browser in its new ChatGPT desktop app, which supports tabs, downloads, website logins, autofill, password management, extensions, and persistent browser state.
- OpenAI recommends its Chrome extension for users needing an existing Chrome profile, signed-in session, open tabs, or other extensions, and the desktop app's "computer use" feature can optionally control Safari with permission.
- ChatGPT conversation history is stored separately from Atlas and will remain available after the browser shuts down.
- Anthropic is pursuing a similar two-track approach, offering Claude Code's sandboxed in-app browser alongside a Chrome extension that works with existing logged-in sessions.
Why it matters: Anyone still running Atlas after Sunday faces an unsupported browser with no security patches and must manually export bookmarks and migrate — a notable retraction for OpenAI after Atlas launched as a dedicated AI-first browser.
