The tester noted the Rust rewrite's measured performance gain was tiny, 0.1% in a micro-benchmark, and that Kimi K3.1 Pro's value lies in its planned availability as an open-weights model that can run locally rather than in online performance or cost. The tester said open-weight models like Kimi K3.1 appear to deliver comparable results, a concern for Anthropic.", "body_md": "When a **new model** is released, it is interesting to test it out to see how the LLM landscape is changing. If you are considering buying Anthropic IPO stock (I am not) this can also be worthwhile. I tried **Kimi K3.1 Pro** on OpenRouter and had it analyze a small **Rust function**.\n\nKimi K3.1 Pro took about **4 minutes** to analyze the code and returned a simpler version. It was not sure if the new Rust function would be faster, due to the complexities of compiler optimizations. The cost was about $0.08, which is somewhat **expensive** for this sort of task.\n\n• The performance gain from the Rust function (when it can be measured) is tiny (0.1% in a micro-benchmark).\n\n• The value of Kimi K3.1 Pro is not in its performance online, or its costs, but that it will be available as an open-weights model available to run locally.\n\n• As far as Anthropic goes, I would be concerned—open-weight models like Kimi K3.1 seem to have comparable results.", "url": "https://wpnews.pro/news/kimi-k3-1-pro-for-code-analysis", "canonical_source": "https://www.dotnetperls.com/2026_10_26_kimi-k3-1-pro-code-analysis", "published_at": "2026-10-26 07:00:00+00:00", "updated_at": "2026-10-26 15:15:03.330974+00:00", "lang": "en", "topics": ["large-language-models", "ai-tools", "ai-research"], "entities": ["Kimi K3.1 Pro", "OpenRouter", "Anthropic", "Rust"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/kimi-k3-1-pro-for-code-analysis", "markdown": "https://wpnews.pro/news/kimi-k3-1-pro-for-code-analysis.md", "text": "https://wpnews.pro/news/kimi-k3-1-pro-for-code-analysis.txt", "jsonld": "https://wpnews.pro/news/kimi-k3-1-pro-for-code-analysis.jsonld"}}
