    1.65万亿美元表外承诺与166倍Token价差:AI资本游戏的三种终局推演

    作者梳理美国五大科技巨头的财报发现,Alphabet和亚马逊超85%的季度利润来自股权投资浮盈,表外长期采购与租约承诺合计约1.65万亿美元,已超过表内负债。2026年五巨头资本开支预计7692亿美元,而AI应用年收入约2000亿美元,存在约5倍缺口。作者对比中美定价后指出,OpenAI输出30美元/百万Token、DeepSeek仅0.18美元,价差达166倍,并判断最可能的终局是某个节点率先出问题后经交叉持股链式传导。

    倍。甲骨文隐性承诺在2026年5月底超过2700亿美元,四年膨胀超30倍。Alphabet表外承诺估算约2500亿美元。 这套操作,很多人会联想到2001年安然。安然当年就是利用SPV把巨额债务移出资产负债表,同时用市值计价会计,在签约当年确认未来多年预期收入,最终轰然倒塌。 二者有本质区别:安然的收入几乎全部虚构。当下科技巨头的云算力收入真实存在,谷歌云、AWS确实在向客户售卖算力。问题在于,利润被股权投资浮盈严重美化,真实自由现金流持续恶化,产业链买卖双方高度绑定,形成内部循环。 三、一道算不平的算术题 我们把投入端和收入端拆开看,缺口一目了然。 投入端:五大巨头2026年合计资本开支预计达到7692亿美元,几乎是2025年的两倍,机构预估2027年资本开支最高或将冲击1万亿美元。 收入端:中金测算,AI应用赛道,每年需要形成约1万亿美元可持续稳定收入,才能覆盖全部资本开支与债务成本。当前美国头部模型厂商合计年度经常性收入ARR大约2000亿美元。中间存在5倍缺口。 伦敦证券交易所集团预测:2027年五大科技巨头经营现金流预计增加3400亿美元,但同期资本开支预计增加5340亿美元

    Nace.AI 开源了 Drex 1.5,一个 8.95B 稠密决策模型,不生成文本,而是读取状态和带类型的问题后为每个选项返回概率,权重已发布在 Hugging Face,OpenRouter 上有托管版本。它在公开 Decision Index 0.3.1 上得分 58.08,与闭源模型 Jev 1.13.0 的 57.96 处于同一并列区间,在 37 项基准中有 20 项领先。模型默认上下文 16,384 tokens、最高 131,072,可在单张 24 GB A10G 上以 bf16 运行,Q8_0 GGUF 约 9.5 GB 可跑在 Apple 芯片和 CPU 上,但 GPQA Diamond 仅 45.4%、ACOS 情感分析 F1 仅 7.4%。

    Anthropic 限制华为 AI 芯片使用 Claude Opus 5.5 开发前沿模型

    Anthropic 在 Claude Opus 5.5 中加入针对前沿 LLM 开发场景的分类器,当请求涉及为特定 AI 加速器开发内核时,模型会自动回退到 Opus 5。用户测试显示,至少华为昇腾950DT 和亚马逊 Trainium3 会触发这一限制,Anthropic 未说明 Trainium3 为何被纳入。Anthropic 表示该机制不影响绝大多数传统 AI、机器学习研究和普通编程任务,并同步加强了反蒸馏措施,包括限制 API 用户修改此前对话上下文。

    目前尚不清楚这种情况究竟是Anthropic有意为之,还是分类器在识别特定AI芯片时产生了意外的误判。相关测试显示,Opus 5.5似乎能够识别不同硬件平台,并根据请求内容决定是否允许使用最新模型,但Anthropic并没有公开说明为什么Trainium3会与华为950DT同时触发限制。 这种情况尤其值得注意,因为Anthropic此前一直强调其模型可以通过AWS等云平台广泛提供,而Opus 5.5目前也已经正式登陆Amazon Web Services、Google Cloud和Microsoft Azure等平台。如果未来这种限制扩大到更多用于训练先进模型的AI加速器,那么云计算企业和AI模型公司的合作关系可能需要在模型能力、硬件支持以及安全限制之间进行更加复杂的协调。 从技术角度看,Anthropic这次的做法也反映出一个新的趋势:随着AI模型本身开始能够帮助人类设计和优化下一代AI模型,模型厂商需要开始区分“使用AI开发应用”和“使用AI开发更强的AI”这两类任务。 对于普通程序员而言,让Opus 5.5帮助编写应用程序、调试代码或者进行机器学习实验,通常不会触发特殊限制。但如

    特朗普强推“super intelligence”改名,AI行业术语之争升温
