The evaluation also highlighted Sol's advanced cyber capabilities at a higher cost, while Fable refused to complete the benchmark entirely.", "body_md": "Based on internal evals:\n▪️ Kimi K3 is top-tier at cybersecurity\nThere is chatter on X that Moonshot benchmark-overfit. These are stealth evals. Model has raw IQ.\n▪️ Sol is a leap ahead in cyber capability\nAt a significantly higher cost, but quite remarkable still.\n▪️ Fable refuses everything\nWe couldn’t get it to complete the run at all. What’s interesting is that Sol in comparison was much more open to helping with defensive cyber hardening\nTL;DR: frontier, open-weight cybersecurity capability is here. Try it on\n\n[deepsec.sh](http://deepsec.sh)for defensive purposes.We ran Kimi K3 on a private cybersecurity benchmark.\nTL;DR: Kimi K3 is the workhorse for cyber security tasks at great recall/precision/price. GPT 5.6 is best recall/precision but at 7x higher cost per run.\nFor context,", "url": "https://wpnews.pro/news/kimi-k3-is-top-tier-at-cybersecurity", "canonical_source": "https://twitter.com/rauchg/status/2078647648307880209", "published_at": "2026-07-19 07:22:16+00:00", "updated_at": "2026-07-19 07:51:17.483584+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-products", "ai-safety", "ai-research"], "entities": ["Moonshot AI", "Kimi K3", "Sol", "Fable", "GPT 5.6", "deepsec.sh"], "alternates": {"html": "https://wpnews.pro/news/kimi-k3-is-top-tier-at-cybersecurity", "markdown": "https://wpnews.pro/news/kimi-k3-is-top-tier-at-cybersecurity.md", "text": "https://wpnews.pro/news/kimi-k3-is-top-tier-at-cybersecurity.txt", "jsonld": "https://wpnews.pro/news/kimi-k3-is-top-tier-at-cybersecurity.jsonld"}}
