前沿AI进入封闭阵营：访问权成为新稀缺
The Price of Entry to the Frontier
The frontier AI market is sorting itself into closed camps, as labs pick partners, cut rivals, & ration access to their strongest models.
前沿人工智能市场正逐渐分化为封闭阵营，各实验室通过选择合作伙伴、打压竞争对手以及限制对其最强模型的访问权限来划定界限。
Salesforce chose Anthropic as its dedicated AI partner, making Claude the default model inside the world’s largest CRM & Slack. 1 OpenAI cut Cursor’s API access on November 12 after SpaceX bought the company, citing prior contract breaches. 2 Even the open weights models now impose gates : Z.ai released GLM-5.3-Flash under an MIT license on August 26 & put its flagship behind a $10b host-revenue review two days later. 3
Salesforce 选择了 Anthropic 作为其专属 AI 合作伙伴，使 Claude 成为全球最大 CRM 和 Slack 中的默认模型。1 OpenAI 于 11 月 12 日切断了 Cursor 的 API 访问权限，原因是 SpaceX 收购了该公司，理由是存在先前的合同违约行为。2 即使是开源权重的模型现在也设置了门槛：Z.ai 于 8 月 26 日以 MIT 许可证发布了 GLM-5.3-Flash，并在两天后将其旗舰模型置于需审查 100 亿美元主机收入的门槛之后。3
Anthropic started the pattern this summer. Mythos 5, its strongest model, now ships only through Project Glasswing, a program that rations certain capabilities to trusted companies. 4
Anthropic 今年夏天开启了这一模式。其最强模型 Mythos 5 目前仅通过 Project Glasswing 项目发布，该项目向受信任的公司分配特定能力的访问权限。4
Fable, its sibling, went dark outside the United States for three weeks, then returned to US-only inference. 4
其姊妹模型 Fable 在美国境外消失了三周，随后恢复为仅限美国地区的推理服务。4
OpenAI made the mirrored choice, launching its government-facing GPT-5.6 variants to a small group of trusted partners before any public API. 5 Governments are getting in on the act, deciding who may run the frontier at all.
OpenAI 做出了镜像般的决定，在面向公众的 API 推出之前，率先向其政府对接的 GPT-5.6 变体版本向一小群受信任的合作伙伴开放。5 各国政府也开始介入，决定谁有资格运行前沿技术。
Salesforce hardcoding Claude is de rigueur ; SaaS apps pick their components & pass them on a single app to the customer : take-it-or-leave-it.
Salesforce 硬编码 Claude 已成为行业标配；SaaS 应用选择其组件并将它们打包成单一应用程序提供给客户：要么接受，要么放弃。
The pluggable, model-agnostic ideal lived primarily in coding tools where developers expected to swap backends at will.
可插拔、与模型无关的理想状态主要存在于编程工具中，开发者期望能够随意切换后端。
Enterprise buyers face an escalating governance challenge : strict Zero Data Retention policies, data sovereignty mandates, & an increasing wariness of sending their IP out the door in prompts. When platforms hardcode a single provider’s models, buyers must negotiate for leverage to be able to change it.
企业买家面临着日益严峻的治理挑战：严格的零数据保留政策、数据主权要求，以及对将知识产权通过提示词发送出去的日益警惕。当平台硬编码单一提供商的模型时，买家必须争取谈判筹码以保留更换的能力。
All of this to say, frontier AI is no longer a utility sold by the token. Labs are developing whitelists & blacklists.
总而言之，前沿人工智能不再是以 token 计费的公用事业产品。实验室正在建立白名单和黑名單。
Even the era of permissive open-source weights is narrowing. Model creators are introducing free-to-pay conversion thresholds, a form of product-led growth, allowing open experimentation for developers while requiring revenue-triggered security reviews & commercial licensing for large cloud hosts. Open source now means open until you scale.
即使是宽容的开源权重时代也在收窄。模型创建者引入了免费到付费的转换阈值，这是一种产品驱动的增长形式，允许开发者进行开放式实验，同时要求大型云主机在触发收入时需进行安全审查并获得商业许可。现在的开源意味着“在你规模化之前都是开放的”。
Governments are treating frontier AI as critical sovereign infrastructure, using export restrictions, nationality screening, & specialized model tiers to police who runs the frontier.
各国政府将前沿人工智能视为关键的主权基础设施，利用出口管制、国籍筛查和专门的模型层级来监管谁有权运行前沿技术。
Pushing back against this closure is a $5t countervailing force : Nvidia, leveraging its market cap to invest in open ecosystems. & they’ve been active : $13b for Hugging Face, $7b for Poolside’s model factory, & a $26b commitment to Nemotron. 6 & the list continues.
对抗这一封闭趋势的5万亿美元反制力量是英伟达，它正利用其市值投资开放生态系统。& 他们一直非常活跃：向Hugging Face投资130亿美元，向Poolside的模型工厂投资70亿美元，并承诺260亿美元支持Nemotron。6 & 名单还在继续。
Open weights are its structural defense against its own cloud customers, ensuring foundation models cannot be entirely gated by proprietary labs or sovereign restrictions.
开放权重是其针对自身云客户的结构性防御，确保基础模型不会被专有实验室或主权限制完全封锁。
Access, not price, is the new scarcity at the frontier.
在前沿领域，获取权限而非价格才是新的稀缺资源。
