- **name:** ChatGPT Atlas (agent mode)
- **operator:** OpenAI
- **purpose:** agentic-browsing
- **ua_substring:** 
- **robots_token:** (none — agentic browser; no published robots.txt token)
- **respects_robots:** no
- **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.
- **citation_referral_value:** medium (acts on a user's behalf in-browser; can surface and act on your page for that user)
