当威胁以机器速度蔓延时,人类防御者根本无法跟上。更糟的是,无法由你掌控的防御并非防御,而是暴露风险。安全团队在掌握主动权时,才能发挥最佳表现。Mistral 的 ML4 让防御者能够审计架构、部署在自己的基础设施上,并完全掌握自主权。韧性始于自主,而开放权重模型有助于组织掌控局面,主导自身防御。When threats move at machine speed, human defense cannot keep pace. Worse, a defense you don’t control isn’t defense—it’s exposure. Security teams perform best when they take the steering wheel. Mistral's ML4 lets defenders audit the architecture, deploy on their own infrastructure, and keep full sovereignty. Resilience starts with autonomy, and open-weight models help give organizations the control to lead their own defense."

网络安全漏洞分诊:智能体读取收到的漏洞报告,调查源代码和产品背景,在隔离沙箱中复现漏洞,然后编写并迭代修补程序,直到金丝雀漏洞利用不再奏效。Cyber Vulnerability Triage: an agent reads incoming vulnerability reports, investigates the source code and product context, reproduces the flaws in an isolated sandbox, then writes and iterates on a patch until a canary exploit no longer works.

智能体式 Web 开发:无需人工协助,Mistral Large 4 构建了 Orbital Trace——一张实时 3D 地图,展示绕地球运行的大约 19,000 颗卫星和碎片。它获取真实的追踪数据,编写应用,在浏览器中运行应用以发现自身的错误和性能瓶颈,然后修复独立审查者指出的问题,直到满足所有要求。Agentic webdev: with no human help, Mistral Large 4 builds Orbital Trace, a live 3D map of roughly 19,000 satellites and debris pieces orbiting Earth. It pulls real tracking data, writes the app, uses it in a browser to catch its own bugs and slowdowns, then fixes what an independent reviewer flags until all requirements pass.

量子化学求解器:Mistral Large 4 从零开始编写软件,用来计算分子中电子的位置,并将计算结果与标准化学工具进行比对。随后,它围绕该软件构建了一个 3D 页面:选择苯或水等分子,拖动滑块将其拉开,观察化学键断裂时电子如何重新分布。Quantum chemistry solver: Mistral Large 4 writes, from scratch, software that calculates where electrons sit in a molecule, and checks its answers against a standard chemistry tool. It then builds a 3D page around it: pick a molecule such as benzene or water, drag a slider to pull it apart, and watch the electrons regroup as the bond breaks.

为主权而打造。Built for Sovereignty.

随着组织围绕自身知识和工作流程构建 AI,主权意味着它们能够掌控所依赖的模型以及所创造的智能。As organizations build AI around their knowledge and workflows, sovereignty means that they retain control of the models they depend on and the intelligence they create. 

借助 Mistral Large 4,这种掌控力始于模型本身。各组织能够检查、定制模型,并将其部署在自己的基础设施上。它们可以使用并改进 Mistral Large 4,而无需依赖 Mistral 通过 API 提供服务。Mistral Large 4 在欧洲从零开始开发和训练,让各组织清楚了解自己所依托技术的来源。With Mistral Large 4, that control begins with the model itself. Organizations have the ability to inspect, customize, and deploy the model on their own infrastructure. They can use and improve Mistral Large 4 without depending on Mistral to serve it through an API. Mistral Large 4 was developed and trained from scratch in Europe, giving organizations clarity about the origins of the technology they’re building on. 

控制权也延伸至 AI 在组织内部的运行方式。组织可以借助 Mistral Forge,围绕专有数据定制 Mistral Large 4;还可以使用 Mistral Studio 构建、管理并改进由此生成的智能体和应用。Mistral 的应用人工智能专家可以与客户团队协作,共同构建和部署这些定制系统。在这一过程中,团队能够了解所构建系统背后的架构和决策,以及训练和运行系统所用的方法,从而独立运行并改进自己的 AI。Control also extends to how AI operates inside an organization. Organizations can customize Mistral Large 4 around their proprietary data with Mistral Forge, and they can build, govern, and improve the resulting agents and applications using Mistral Studio. Mistral’s Applied AI experts can work alongside customer teams to build and deploy these tailored systems. Through that work, teams understand the architecture and decisions behind what they’ve built, along with the methods used to train and operate it, so they can run and improve their AI independently.

在 ABN AMRO,我们相信,开放透明的 AI 生态系统对于推动金融领域以负责任的方式创新至关重要。Mistral Large 4 等进展表明,主权 AI 模型和开放权重 AI 模型能够为欧洲组织拓展可信解决方案的选择范围。我们对目前取得的进展感到鼓舞,并将继续探索先进 AI 如何助力强化关键能力,包括网络安全。At ABN AMRO, we believe that open and transparent AI ecosystems are essential for driving innovation responsibly within the financial sector.

强大的模型只是成功的一部分。开发者还需要自主决定模型的运行位置、优化方式,以及如何将其融入自己的系统。我们对 Mistral Large 4 感到振奋,因为开放权重让开发者能更好地掌控这些决策,而不必依赖单一的托管服务。在 ZML,我们认为,这种自主权对于将 AI 的进步转化为实用、可部署的软件至关重要。A powerful model is only part of the equation. Developers also need the freedom to decide where it runs, how it is optimized, and how it fits into their systems. We’re excited about Mistral Large 4 because open weights give builders more control over those decisions, rather than making them dependent on a single hosted service. At ZML, we see that freedom as essential to turning advances in AI into useful, deployable software.
