智通财经APP获悉，近日，第四范式(06682)高级副总裁俞晖，出席备受全球科技界瞩目的华为开发者大会2025(HDC 2025)，并发表「基 于OpenHarmony+海思芯片打造AI智能硬件的实践分享」，重点阐述了在Agent加速发展的2025年，第四范式对端侧模型的探索，以及其 对于鸿蒙生态的贡献。 端侧革命：开发模式的重构与第四范式新生态 俞晖首先分享了传统云端模型与第四范式专注的端侧模型之间的区别。传统云端模型依赖网络传输数据至云端处理，存在「延迟高、隐 私风险大、离线不可用」三大痛点。而端侧模型通过本地化部署模型，在响应速度、隐私保护、降低成本方面都有着不俗的表现。 与此同时，第四范式在十多年的端侧模式开发中，打造了一个开放平台。相比传统开发模式的固定化、指定性(某1-2人做某个模型)，今 天是"你想做就可以参与"，"像一个榜单、一个擂台、一个竞技场"。这样的好处是每个人都有机会，模型效果的上限也不再取决于某1-2 人的水平，而是所有参与到其中的人员的上限。 "把复杂留给操作系统，把简单留给开发者。" 俞晖对HDC主论坛上的这样一句话印象深刻、高度赞同，他表示上述的开发平台、端侧模型能力并不会封闭 ...

国产 AI 算力进展汇报 20250622 摘要 H20 断供初期引发市场对 AI 算力芯片供给的担忧，导致短期资本开支下 调和招标延缓，尤其以 2025 年第二季度最为严峻，主要受英伟达新款 芯片不确定性和中芯国际产能影响。但第三季度起，AI 芯片供给边际改 善，利好国产算力板块。 英伟达 B30、B40 入华进展是市场关注焦点，若第三季度相关厂商能顺 利拿到板卡并测试（尤其带有 Nvlink），巨头可能规模下单，缓解部分 缺芯问题。这两款芯片虽算力低于 H20，但 Nvlink 对巨头仍具吸引力。 算力租赁市场发展顺利，主要用于训练，租用卡型号逐步升级至更高性 能型号，为解决短期缺芯问题提供重要途径。这缓解了因 H20 断供带来 的部分算力压力。 中芯国际 2025 上半年产能受阻，但 7 月起逐步修复，预计第三季度产 能将复苏。H20 断供后，国产卡需求增加，巨头通过自研或加单国产芯 片弥补缺口，预计 2026 年国内产能释放将迎来机会。 国内巨头对 AI 投资决心坚定，算力投入与公有云营收增长息息相关。阿 里云和腾讯云最新财报显示快速增长，持续投入新的算力资源是刚性需 求，总服务器需求甚至有所提升。 ...
