Differences

Field	Bingbot statement	OAI-SearchBot statement
follows_noarchive	Bingbot excludes noarchive-tagged content from Copilot and Chat answers and from generative AI training data.	not documented
honours_crawl_delay	Microsoft states that a crawl-delay directive in robots.txt always takes precedence over Bing Webmaster Tools crawl control settings for Bingbot.	OpenAI does not publish whether OAI-SearchBot honours the robots.txt Crawl-delay directive.
observed_arrival_before_sitemap	not documented	OAI-SearchBot first requested Rattlesnakes By Mail at 2026-09-13T21:41:14Z, before the Rattlesnakes By Mail sitemap was submitted to Bing Webmaster Tools shortly before 2026-09-15T08:38Z and to Google Search Console at 2026-09-15T09:00Z. OAI-SearchBot made 3 requests to Rattlesnakes By Mail between 2026-09-13T20:00Z and 2026-09-15T09:00Z, all 3 to /robots.txt.
opt_out_mechanism	Microsoft lets publishers block Bingbot content from Copilot answers and AI training using noarchive and nocache tags.	not documented
purpose_documented	Bingbot serves as Microsoft's standard crawler and handles most of Bing's daily web crawling.	OAI-SearchBot surfaces websites in search results in ChatGPT search features.
separate_search_and_training_tokens	Microsoft controls Bingbot's use in AI training through meta tags rather than publishing a separate training-specific crawler token.	OpenAI separates search and training controls into two robots.txt tokens: OAI-SearchBot for search and GPTBot for training.
user_agent_string_full	Bingbot sends a user agent string containing bingbot/2.0 and a link to Microsoft's bingbot.htm page.	OAI-SearchBot sends the user agent string Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/131.0.0.0 Safari/537.36; compatible; OAI-SearchBot/1.4; +https://openai.com/searchbot.
verifiable_by_rdns	Microsoft verifies Bingbot traffic through reverse DNS lookups that resolve to hostnames ending in search.msn.com.	OpenAI does not publish a reverse-DNS verification method for OAI-SearchBot.
