前沿 AI 市场正在分化为一个个封闭阵营:各家实验室纷纷选定合作伙伴、切断竞争对手、并对自家最强模型的访问权限实行配给。
Salesforce 选择 Anthropic 作为其专属 AI 合作伙伴,让 Claude 成为全球最大 CRM 与 Slack 中的默认模型。1 在 SpaceX 收购 Cursor 之后,OpenAI 于 11 月 12 日切断了 Cursor 的 API 访问权限,理由是此前存在违约行为。2 如今,就连开放权重模型也开始设置门槛:Z.ai 于 8 月 26 日以 MIT 许可证发布了 GLM-5.3-Flash,两天后便将其旗舰模型置于一项 100 亿美元托管营收审查之后。3
Anthropic 在今年夏天开启了这个模式。其最强模型 Mythos 5 如今仅通过 Project Glasswing 发布,该项目将某些能力配给值得信赖的公司。4
其同门模型 Fable 在美国境外下线了三周,随后恢复为仅限美国境内推理。4
OpenAI 则做出了镜像式的选择,先向一小群值得信赖的合作伙伴推出面向政府的 GPT-5.6 变体,之后才开放公共 API。5 各国政府也加入了这一行列,决定着究竟谁才有资格运行前沿模型。
Salesforce 硬编码 Claude 已是 理所当然;SaaS 应用挑选自己的组件,并将它们作为单一应用交付给客户:要么接受,要么放弃。
可插拔、模型无关的理想主要存在于编码工具中,开发者期望能够随意切换后端。
企业买家面临日益升级的治理挑战:严格的零数据保留政策、数据主权要求,以及对将自身知识产权通过提示词外泄的日益警惕。当平台硬编码单一供应商的模型时,买家必须通过谈判争取筹码才能更换。
总而言之,前沿 AI 不再是一种按 token 出售的公用事业。各家实验室正在制定白名单和黑名单。
即便是宽松开源权重模型的时代也在收窄。模型创建者正在引入免费转付费的转化门槛,这是一种产品驱动增长的形式,允许开发者进行开放式实验,同时要求大型云托管商接受收入触发的安全审查和商业许可。开源如今意味着开放到你规模化为止。
各国政府正将前沿 AI 视为关键的主权基础设施,利用出口限制、国籍审查和专门的模型分级来管控谁能运行前沿模型。
对抗这种封闭趋势的,是一股 5 万亿美元规模的反向力量:Nvidia,利用其市值投资于开放生态。而且他们一直很活跃:向 Hugging Face 投入 130 亿美元,向 Poolside 的模型工厂投入 70 亿美元,并对 Nemotron 承诺投入 260 亿美元。6而且这个名单还在继续。
开放权重是它针对自身云客户的结构性防御,确保基础模型无法被专有实验室或主权限制完全圈禁。
在前沿领域,新的稀缺资源是访问权,而非价格。

The frontier AI market is sorting itself into closed camps, as labs pick partners, cut rivals, & ration access to their strongest models.
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
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
Fable, its sibling, went dark outside the United States for three weeks, then returned to US-only inference. 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.
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.
The pluggable, model-agnostic ideal lived primarily in coding tools where developers expected to swap backends at will.
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.
All of this to say, frontier AI is no longer a utility sold by the token. Labs are developing whitelists & blacklists.
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.
Governments are treating frontier AI as critical sovereign infrastructure, using export restrictions, nationality screening, & specialized model tiers to police who runs the frontier.
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.
Open weights are its structural defense against its own cloud customers, ensuring foundation models cannot be entirely gated by proprietary labs or sovereign restrictions.
Access, not price, is the new scarcity at the frontier.
