2025年的AI战场，已从单一的模型性能竞赛，演变为芯片、软件栈、云服务与开源生态的四维立体战争。 1）对OpenAI：其挑战不仅是谷歌Gemini模型性能的追赶，更是其依赖外部算力的重资产模式，表现为对微软的重度依赖，在面临谷歌TPU低TCO优势 时的根本性成本危机。 2）对英伟达：真正的威胁并非另一家GPU设计商，而是一个从硬件到软件、从应用到生态完全垂直整合，并试图用开源策略"农村包围城市"的替代系 统。 3）对行业：谷歌的崛起标志着AI基础设施领域"垂直整合"模式对"水平分工"模式的强力挑战。开源力量的壮大则确保了技术的多样性与可及性，一个多 极共存、而非一家独大的全新AI世界正在加速形成。 4）架构固定化确实撕开了一道口子，降低了专用芯片的入场门槛，使英伟达从"唯一的选项"变成了"选项之一"。甚至可以说，谷歌TPU的出现，英伟达 不仅需要面对在推理端的市场竞争，也将开始首次面对在训练端的市场竞争。 早在2015年，谷歌就为加速搜索排名和AlphaGo秘密部署了第一代TPU张量处理单元。自此，谷歌走上了一条截然不同的道路：为其最核心的AI工作负 载，定制设计专用TPU芯片、互连网络、冷却系统乃至专属编 ...
