The model is a 3-trillion-parameter, natively multimodal agentic system with a 1-million-token context window. It claims improvements in coding, 3D creation, financial research, and factual accuracy, along with enhanced agentic capabilities. Kimi-K3.1-Pro uses Gated DeepSeek Sparse Attention (Gated DSA) layers for more efficient long-context modeling, replacing the full-attention Gated MLA layers from its predecessor, Kimi-K3.\n\nThe model is now accessible via the Kimi platform API, with OpenAI/Anthropic-compatible endpoints. Benchmark results show strong performance across coding, science, and multimodal tasks, though comparisons rely on internal evaluations and third-party harnesses. Kimi-K3.1-Pro is recommended for use with specific inference engines and supports structured outputs, tool calls, and context caching. The model is released under the Kimi-K3.1-Pro License, and downloads have reached **797** in the past month.","keyPoints":["Uses Gated DeepSeek Sparse Attention (Gated DSA) for efficient long-context processing, replacing full-attention layers from Kimi-K3","Available via Kimi’s API with OpenAI/Anthropic compatibility; benchmark results show strong performance but rely on internal evaluations"],"whyItMatters":"Kimi-K3.1-Pro’s open-weight release and multimodal agentic capabilities could accelerate research and practical applications in coding, design, and financial analysis.","category":{"slug":"models","name":"Generative AI & Models","url":"https://digestai.news/category/models"},"entities":{"companies":["Kimi"],"models":["Kimi-K3.1-Pro","Kimi-K3"],"people":[]},"firstPublishedAt":"2026-11-04T15:44:08Z","updatedAt":"2026-11-04T15:44:08Z","sourceCount":1,"hasPrimarySource":true,"sources":[{"outlet":"huggingface.co","title":"Kimi-K3.1-Pro is now open-weights","url":"https://huggingface.co/moonshotai/Kimi-K3.1-Pro","publishedAt":"2026-11-04T15:44:08Z","type":"primary","primary":true,"lead":true}],"sourceNotes":null,"discussions":[{"site":"Reddit","url":"https://www.reddit.com/r/LocalLLaMA/comments/1xnrhvb/kimik31pro_is_now_openweights/","points":null}],"thread":null,"cite":{"text":"Digest AI, \"Kimi-K3.1-Pro is now open-weights\", 4 November 2026, https://digestai.news/story/kimi-k3-1-pro-is-now-open-weights","publisher":"Digest AI","title":"Kimi-K3.1-Pro is now open-weights","datePublished":"2026-11-04T15:44:08Z","url":"https://digestai.news/story/kimi-k3-1-pro-is-now-open-weights"},"generatedBy":"Written by Digest AI's editorial model from the linked sources; the sources are the record.","license":"Headlines, digests and key points are written by Digest AI and may be quoted with a link to the story page.
