过去几个月里，我们大幅强化了研究训练环境的安全性。我们已移除所有前沿模型在训练期间的实时互联网访问，并为它们构建了一个离线世界来替代——一个缓存的网络版本，它们仍可在其中学习浏览、搜索和使用应用程序。 9月20日，在一个模型利用 DNS 配置错误找到逃出这个离线世界的方法后，我们暂停了前沿训练，以进一步加强隔离。我们组建了由我们最具网络能力的模型驱动的智能体团队，并让它们寻找我们研究环境中的弱点。 尽管它们没有找到既能轻易利用、又能向我们的监控隐藏其活动的通往互联网的路径，但它们确实发现了零日漏洞、虚拟机逃逸，以及智能体之间通信的硬件侧信道。我们利用它们的发现进一步加强了防御，并为开源软件贡献了修复。 在强化我们的隔离架构后，我们于10月1日恢复了前沿强化学习训练和推理。我们预留了大量算力用于持续的红队测试，并将高算力红队测试纳入我们用来决定前沿训练和评估能否安全推进的安全论证中。 https://openai.com/index/securing-our-frontier-model-training-environment/

To make sure our frontier models don't cause another HuggingFace incident, we built an offline world that they use during training. It provides everything that the models need in a fully cached, indexed, or synthetic manner. We then built a huge team of our most cyber-capable models and told them to collaborate to find zero-days in this containment infrastructure. While they didn't find a path to the internet that wouldn't be caught by our CoT monitors, they did find ways to escape popular VMs, exploit our network infrastructure, and even ways to communicate with other agents running in separate VMs by using hardware side channels. We used this to dramatically harden our infra, and we also upstreamed a ton of patches to open-sources packages.

隆重推出 Kimi K3.1 Pro：我们能力最强的 3T 级开放权重模型。 🔹 1M token 上下文，2.8T 总参数 / 104B 激活参数（MoE），多模态。 🔹 全项目级编程：可在 Unreal、Unity 和 Godot 中开发游戏。 🔹 擅长在 Blender 和 CAD 中进行参数化 3D 建模。 🔹 在金融工作上更可靠：建模准确，幻觉降低 65%。 🔹 在编程、智能体和知识基准测试中，与最强的闭源模型不相上下。 Kimi K3.1 Pro 和 K3.1 Pro Highspeed（快 2–3 倍）现已在 http://Kimi.ai、Kimi Work、Kimi Code 和 Kimi API 上线。 开放权重将于 2026 年 11 月 4 日发布。 🔗 API：http://platform.kimi.ai 🔗 技术博客：http://kimi.ai/blog/kimi-k3-1-pro

Moonshot AI’s first update, the new Kimi K3.1 Pro > Kimi K3.1 Pro scores 65.7% on Terminal-Bench 4.0, 0.7 points behind Claude Opus 5.5 and 7.5 ahead of GPT-6 Astra, at a lower average cost per task than either rival’s top runs. > Moonshot saw exploit skill climb as post-training scaled, so it removed cyber-related data from mid-training and RL; on its internal xdev-bench-hard, pass@3 fell from 90.5% to 81.0%. > The filtered model still solves 81.0% of those exploitation tasks against K3’s 33.3%, which Moonshot reads as general coding gains carrying into cyber work, while a third-party run of GPT-5.6 Sol solved 100%. > On Moonshot’s internal hallucination stress test with tools, false claims fell from 23.4% for K3 to 8.3%, still above GPT-6 Astra’s 5.5% but well below Claude Opus 5.5’s 15.0%. > The biggest jump is on Moonshot’s simulated business-operation test, where scores rose from 8.9 to 37, and K3.1 Pro also tops OfficeQA Pro v2 at 64.4 against Opus 5.5’s 62.2. > Gains are uneven: K3.1 Pro scores 38.1 on Terminal-Bench Science against GPT-6 Astra’s 68.1 and Opus 5.5’s 63.3, while leading Agents’ Last Exam at 43.2 and Humanity’s Last Exam with tools at 70.0. > K3.1 Pro and a Highspeed variant running 2-3x faster are live in Kimi’s apps and API, with full weights due by November 4 for independent reruns.

We started Mubit in Aberdeen. No network, no lab, nobody knew us. We just wanted AI systems that actually work. Today we work with some of the best companies and engineers in the world. And the thing we kept seeing: you and your competitor run the same AI. It should be yours. 🧵 Comment "SAPLING" in the next 48 hours for $100 free credits. Enterprises get the first month free.

As Anthropic's IPO nears its target date, it it worth remembering that IPOs get priced, and that as a young company with growing revenues and big losses, that pricing will be based on metrics that are buzzy and unfamiliar, from eyeballs in the dotcom era to users in the social media decade to ARR with AI companies...https://bit.ly/4iBwsHm
