ChatGPT Search is an established search feature, not a new 2026 launch. This guide explains OpenAI's separate search and training crawlers and what publishers can control.
Table of Contents(6 sections)
Key takeaways
OpenAI introduced ChatGPT Search on October 31, 2024. It is inaccurate to describe it as a new 2026 launch. For publishers, the practical issue is crawler access: OpenAI documents OAI-SearchBot for surfacing pages in ChatGPT search and GPTBot for potential model training. These controls are independent.
- Allowing OAI-SearchBot may permit a page to appear in ChatGPT search; it does not guarantee a citation or referral.
- Blocking GPTBot is a separate choice from allowing OAI-SearchBot.
- Robots.txt is only one access layer; firewalls and bot controls can also block a crawler.
- Measure actual referral visits and outcomes rather than assuming visibility creates conversions.
What ChatGPT Search is—and when it launched
OpenAI announced ChatGPT Search on October 31, 2024, first rolling it out to eligible users and later expanding availability. This is an updated publisher guide, not a report of a new October 2026 product launch.
OAI-SearchBot and GPTBot are different controls
OpenAI's crawler documentation says OAI-SearchBot is used to surface websites in ChatGPT search results. GPTBot is used for crawling that may contribute to model training. OpenAI says the robots.txt settings are independent, so a publisher can allow search crawling while disallowing GPTBot for training use.
A robots.txt rule does not guarantee inclusion, ranking, or citation. OpenAI notes that changes may take time to be reflected. Check current documentation before changing crawler rules, and review access logs and firewall settings.

Publisher checklist
- Decide separately whether to allow OAI-SearchBot and GPTBot, based on your content and licensing preferences.
- Check robots.txt, CDN, hosting firewall, and bot-mitigation rules; a robots.txt allow rule cannot override a firewall block.
- Keep important pages successful, crawlable, and useful, with source links for claims that need support.
- Track ChatGPT referral traffic and landing-page engagement in analytics.
- Recheck OpenAI's current crawler and publisher documentation because product behavior can change.
