- A preview of Agent Mode is restricted to paid tiers, enabling multi‑step tasks such as booking reservations, filling forms, shopping via Instacart, and researching trips with user oversight.
- The macOS app is available globally now, with Windows, iOS, and Android versions planned in the coming months, and OpenAI is pitching the browser to its large ChatGPT user base.
- OpenAI says browsing content isn’t used to train models by default, but a reporter found the Atlas “Model improvement” setting toggled on at first launch, fueling fresh privacy scrutiny.
- Reverse‑engineering points to a Chromium foundation with support for Chrome extensions, and Alphabet shares fell after the launch as security researchers flagged risks from autonomous browser agents.
