- verify
- no stable user-agent and (per OpenAI enterprise docs) no IP allowlist; an agentic browser is identifiable only by IP/signature/behavior, not by a UA token. Treat as user-driven browser traffic.
- notes
- OpenAI's ChatGPT Atlas browser (launched 2025-10-21) embeds ChatGPT into web navigation; its 'agent mode' takes actions on the user's behalf inside the browser. As a local Chromium-based browser it presents like ordinary browser traffic with no stable AI user-agent token — included here per the agentic-browser taxonomy, verifiable by IP/signature only.

- block_vs_allow_recommendation
- conditional — acts inside a real user's browser session; it is not a bulk crawler and cannot be reliably blocked by robots.txt or UA. Manage via session-level / bot-management controls if agent actions are a concern.
