5 big updates coming to the ChatGPT Atlas browser: (www.techradar.com)

OpenAI rolled out a quick “post-launch fix list” for the new ChatGPT Atlas browser, promising five major upgrades that address both standard browser expectations and deeper AI integration. The changes include tab groups and profile switching to separate work/personal contexts, an overflow bookmarks menu and shortcuts for faster navigation, and sidebar enhancements — notably a model picker, access to ChatGPT Projects, multi-tab attachments in the composer, and cleaner @mentions to preserve cross-tab context. Atlas’s Agent mode will also get faster first replies, fewer missed action triggers, smarter waiting behavior and smoother animations. Finally, OpenAI plans an opt-in ad blocker, better captive-portal handling, and improved password manager compatibility. For the AI/ML community these updates matter because they shift Atlas from a demo-like experiment toward a practical, productivity-focused browser where the assistant can operate across multiple tabs and act autonomously. Technically, multi-tab attachments and a model selector enable more contextualized interactions and workflow-specific model choices, while Agent improvements reduce brittle automation behavior. The move signals OpenAI’s intent to compete with Chrome and AI-first browsers, but success depends on stability, security and privacy — especially given increased AI access to tab contents and saved credentials. OpenAI hasn’t given timelines, but the rapid public roadmap suggests fast iteration and close user feedback-driven development.
