Web Crawler
What is KimiBot?
Kimi describes KimiBot as the crawler for content that may be used to train its foundation models, distinct from Kimi-SearchBot. Kimi publishes robots.txt controls and IP ranges for this token. The string collected here contains the KimiBot token but differs from Kimi's current published full user-agent example, so it should not be treated as authenticated Kimi traffic without an IP check.
User Agent String
Mozilla/5.0 (compatible; KimiBot/1.0; +https://kimi.ai/)
How to Control KimiBot
Block Completely
To prevent KimiBot from accessing your entire website, add this to your robots.txt file:
# Block KimiBot
User-agent: KimiBot
Disallow: /
Block Specific Directories
To restrict access to certain parts of your site while allowing others:
User-agent: KimiBot
Disallow: /admin/
Disallow: /private/
Disallow: /wp-admin/
Allow: /public/
Set Crawl Delay
To slow down the crawl rate (note: not all bots respect this directive):
User-agent: KimiBot
Crawl-delay: 10
How to Verify KimiBot
Verification Method:
Compare the source IP with Kimi's current published KimiBot ranges. The collected full user-agent differs from the example in Kimi's documentation.

| Blog/News | Consider Blocking | Your content may be used for AI training without compensation |
| SaaS Application | Block | No benefit for application interfaces; preserve resources |
| Documentation | Selective | Allow for public docs, block for internal docs |
| Corporate Site | Limit | Allow for public pages, block sensitive areas like intranets |
