# Moonshot AI — Kimi K3.1 Pro > AI lab announcements, news reports and podcasts. forck.live follows what companies announce about their own products. Press may corroborate an official story; it never leads and never appears as an item of its own. A missing date stays missing. A title is the publisher's words — where a company does not publish in English, an English rendering is listed separately as `Title in English` and named as this site's translation, never as theirs. This file is the record of one model version: what the model registry states about it, Moonshot AI's launch post, the first-party posts this record holds about it, the outlets that reported on those posts, and other companies' announcements that it runs on their platforms. A model ranks nothing here and nothing is composed: each date names whose it is, and a field nothing states is `not stated` rather than missing. - This model's page: https://forck.live/models/kimi-k3-1-pro - Moonshot AI's page: https://forck.live/company/moonshot-ai - Every model: https://forck.live/models - Catalogue: https://forck.live/llms.txt ## Model - Name: Kimi K3.1 Pro - Company: Moonshot AI (moonshot.ai) - Launch post: Kimi K3.1 Pro — https://forck.live/items/27218-kimi-k3-1-pro - Announced: 2026-10-24 - Launch source: https://www.kimi.ai/blog/kimi-k3-1-pro - Launch chosen by: the earliest dated release post naming it - Released (per models.dev): 2026-10-23 - Listed (per OpenRouter): 2026-10-23 - Open weights: no - Posts about it: 1 - Outlets named under its posts: 19 - Variant of: Kimi K3 — https://forck.live/models/kimi-k3 - OpenRouter id: moonshotai/kimi-k3.1-pro — https://openrouter.ai/moonshotai/kimi-k3.1-pro - Context window: 1-million-token context window — from https://forck.live/items/27218-kimi-k3-1-pro ## Posts about it _Moonshot AI's own posts whose title names Kimi K3.1 Pro, and its launch post, in the record's order: dated newest first, undated last. The record reads the newest 50 first-party posts mentioning the model, every company's together, so a model mentioned more often than that lists the newest of them._ Every entry is one first-party announcement, and carries the same eight fields in this order before any others: Company · Announced · Category · Coverage · Announcement · Group · Source · Record `Source` is the company's own page the announcement was traced to and `Record` is this site's page for it. Both are safe to cite. `Coverage` is a number of outlets, or `not counted` — which means this record reached no count of its own, never that nobody wrote about it. `Category` is this tracker's own analysis, and is authoritative wherever it is stated. `not stated` means either that nothing has analysed the post yet or that the analysis placed it outside this taxonomy; neither is a verdict about the announcement. `Announcement` is whether the post is news of something the company did, rather than a how-to, a customer story, a changelog listing or a staffing note. `Group` is which of this record's groups the entry falls in, carried on the entry itself so it holds where the groups are headings and where they are not. One of: `models`, `covered`, `announcements`, `routine`. Anything after `Record` is held detail that only some announcements carry. ### Moonshot AI — Kimi K3.1 Pro - Company: Moonshot AI (moonshot.ai) - Announced: 2026-10-24 - Category: new-model - Coverage: not counted - Announcement: yes - Group: models - Source: https://www.kimi.ai/blog/kimi-k3-1-pro - Record: https://forck.live/items/27218-kimi-k3-1-pro - Subject: Kimi Moonshot AI introduced Kimi K3.1 Pro, a 3T-class open-weight model with a 1-million-token context window, and a faster Highspeed variant, both available today on Kimi's apps and API. K3.1 Pro is a post-trained version of Kimi K3 with substantially larger post-training compute, which Moonshot says brings consistent gains across every domain. The company says the model matches or approaches the strongest proprietary models on coding, agentic and knowledge benchmarks. On Terminal-Bench 4.0 it scores 65.7%, ahead of GPT-6 Astra (58.2%) and narrowly behind Claude Opus 5.5 (66.4%), and on Kimi Code Bench 3.0 Long-horizon it scores 61.2%, above K3's 55.95%. The Highspeed variant delivers 2-3x the speed of K3.1 Pro and the full model weights will be released by Nov 4. On Kimi Hallu Bench Hard, the claim-level hallucination rate fell from 23.4% for K3 to 8.3%, and 3D Make is now live on kimi.ai and the Kimi app. ## Who reported on it _Outlets this record can name and link, under the first-party post each one covered. Their number is `Outlets named under its posts` above, and the rows are not totalled again. A post's own `Coverage` can be higher: it counts outlets the signal saw that this record cannot name and link._ ### On: Kimi K3.1 Pro Record: https://forck.live/items/27218-kimi-k3-1-pro - Nathan Lambert — Podcast: Kimi K3.1 Pro, the new cyber reality, and Muse musings (2026-10-25T11:49:00+00:00): https://www.interconnects.ai/p/podcast-kimi-k31-pro-the-new-cyber - 新智元 — 刚刚，Kimi K3.1 Pro杀进全球前四，Agent第一！ (2026-10-25T00:05:28+00:00): https://aiera.com.cn/2026/10/25/other/admin/120423/%e5%88%9a%e5%88%9a%ef%bc%8ckimi-k3-1-pro%e6%9d%80%e8%bf%9b%e5%85%a8%e7%90%83%e5%89%8d%e5%9b%9b%ef%bc%8cagent%e7%ac%ac%e4%b8%80%ef%bc%81/ - 机器之心 — Kimi K3.1 Pro：月之暗面端出第一个Pro (2026-10-24T14:27:00+00:00): https://www.jiqizhixin.com/articles/2026-10-24-3 - SiliconANGLE — Moonshot AI launches new flagship Kim K3.1 Pro model with 3T parameters (2026-10-24T00:55:53+00:00): https://siliconangle.com/2026/10/23/moonshot-ai-launches-new-flagship-kim-k3-1-pro-model-with-3t-parameters/ - The Information — Moonshot AI Launches New Kimi K3.1 Pro Model (2026-10-23T22:26:12+00:00): https://www.theinformation.com/briefings/moonshot-ai-launches-new-kimi-k3-1-pro-model - The Decoder — Chinese AI model Kimi K3.1 Pro is closing in on Anthropic's Claude Opus 5.5 (2026-10-23T19:00:07+00:00): https://the-decoder.com/chinese-ai-model-kimi-k3-1-pro-is-closing-in-on-anthropics-claude-opus-5-5/ - Artificial Analysis — Kimi K3.1 Pro launches at 4th on the Intelligence Index and will lead open weights models: https://artificialanalysis.ai/articles/kimi-k3-1-pro-launch-benchmarks - Crypto Briefing: https://cryptobriefing.com/moonshot-ai-kimi-k3-1-pro-hacking-curbs - Crypto Briefing: https://cryptobriefing.com/moonshot-ai-launches-kimi-k3-1-pro-closing-in-on-claude-opus-5-5-in-coding-performance - Extrapolator AI: https://extrapolator.ai/2026/10/23/moonshot-ai-releases-kimi-k3-1-pro-open-weights-with-1m-context - Implicator — Kimi K3.1 Pro Hacking Cut Rests on Unpublished Moonshot Test: https://implicator.ai/kimi-k3-1-pro-hacking-cut-unpublished-test - Madrobot — China’s Kimi K3.1 Pro comes within a point of Claude Opus 5.5 at coding, and its weights will be free: https://madrobot.blog/2026/10/23/kimi-k3-1-pro-moonshot-open-weight-nearly-matches-claude-opus-5-5-coding - RuntimeWire — Kimi's K3.1 Pro launch faces claims of undisclosed creator marketing: https://runtimewire.com/article/kimi-k31-pro-creator-marketing-disclosure-claims - Simon Willison's Weblog — Introducing Kimi K3.1 Pro: https://simonwillison.net/2026/Oct/23/kimi-k31-pro - Tech in Asia: https://techinasia.com/news/moonshot-ai-launches-kimi-k31-pro-plans-openweight-release - The Economic Times — China's Moonshot AI launches Kimi K3.1 Pro; plans full model weights release by November: https://economictimes.indiatimes.com/tech/artificial-intelligence/chinas-moonshot-ai-launches-kimi-k3-1-pro-plans-full-model-weights-release-by-nov/articleshow/135162538.cms - Unite — Moonshot AI Releases Kimi K3.1 Pro, First Model in New K3.1 Series: https://unite.ai/moonshot-ai-releases-kimi-k3-1-pro-first-model-in-new-k3-1-series - VentureBeat: https://venturebeat.com/technology/moonshots-kimi-k3-1-pro-flirts-with-open-weights-leadership-amid-paid-influencer-scandal-allegations - Wccftech — Kimi K3.1 Pro Is Now The Strongest Model Out Of China: Cyber Data Stripped From Its Training But That Barely Holds Its Potential Back: https://wccftech.com/kimi-k3-1-pro-is-now-the-strongest-model-out-of-china-cyber-data-stripped-from-its-training-but-that-barely-holds-its-potential-back - WinBuzzer: https://winbuzzer.com/2026/10/25/kimi-k3-1-pro-gains-ground-in-ai-coding-tests-xcxwbn ## Press chatter — a separate record, not announcements This model's page lists 1 Press chatter entry naming Kimi K3.1 Pro: press coverage and discussion, not first-party announcements, so it is not in this file.
