OpenAI已将公司的计算与基础设施业务交由 Uday Ruddarraju 管理。Ruddarraju 曾在 Elon Musk 的 xAI 公司负责基础设施相关工作，任职至 2025 年 7 月。此前负责基础设施管理的 Sachin Katti 将在几周内离职，但仍会以顾问身份继续为 OpenAI 提供支持。
OpenAI has put its compute and infrastructure businesses under Uday Ruddarraju, who ran infrastructure at Elon Musk’s xAI until July 2025. Sachin Katti, who had been overseeing infrastructure and led the $30B Georgia build, leaves the role within weeks and stays on as an adviser.
据彭博社报道，这一人事调整已于周三公布。Katti 表示自己会继续担任顾问，而他手下的业务负责人们也将继续留任。
OpenAI has put compute and infrastructure under one executive. Uday Ruddarraju, who ran infrastructure at Elon Musk’s xAI, takes both.
Ruddarraju 于 2025 年 7 月加入 OpenAI，并于同年 7 月被任命为公司的首席技术官（负责计算与基础设施部门）。在 xAI 公司期间，他曾参与过使用 10 万台 GPU 进行的 Grok 3 训练项目。
Sachin Katti, who had been overseeing infrastructure, leaves within weeks. Bloomberg reported the change on Wednesday. Katti plans to stay on as an adviser, and the business leaders under him keep their jobs.
“Sachin 在维护商业合作伙伴关系方面做得非常出色，”Ruddarraju 对彭博社表示，“我相信交接工作会进行得很顺利，现在我需要将更多精力投入到公司的商业发展上。”
Ruddarraju joined OpenAI in July 2025 and became chief technology officer for compute this July. At xAI he worked on the Grok 3 training run across 100,000 GPUs.
值得注意的是，OpenAI 在 8 月份并未公开宣布这一任命。当时虽然该公司确认了数据中心负责人的离职消息，但并未透露新任命的首席技术官是谁——后来才确认那个人就是 Ruddarraju。
“Sachin has done an incredible job maintaining the commercial partnerships,” he told Bloomberg. He expects a smooth handover, and said he must now spend more time on the commercial side. The appointment names someone OpenAI would not name in August.
除了 Katti 之外，还有其他高管也离开了 OpenAI：Peter Hoeschele 今年早些时候与两位同事一同加入了 Meta 公司；Keith Heyde 和 Shamez Hemani 则从 Data Center Dynamics 公司离职。
When it confirmed that its data centre chief had left, it had already hired a compute CTO but would not say who. It was Ruddarraju. Chris Malone was not the only exit.
Katti 来自英特尔公司，曾在英特尔担任首席技术官和人工智能部门负责人。据报道，他于去年年底加入 OpenAI，并主导了位于乔治亚州的耗资 300 亿美元的基础设施建设项目（该项目由 OpenAI 自主设计并实施）。他还参与了与 SB Energy 和 Nvidia 合作的俄亥俄州 8 吉瓦瓦特规模的能源项目；Axios 根据相关证券文件报道，Nvidia 为该项目提供了高达 1050 亿美元的租赁和电力费用保障。
Peter Hoeschele, central to Stargate, left for Meta earlier this year with two colleagues. Data Center Dynamics names Keith Heyde and Shamez Hemani. Katti arrived from Intel late last year, where he was chief technology and AI officer, and the same outlet dates his Stargate takeover to March. He oversaw the $30B Georgia site, the first OpenAI designed and led itself. He also oversaw an 8-gigawatt project in Ohio with SB Energy and Nvidia. Nvidia has guaranteed up to $105B in lease and power payments there, Axios reported from a securities filing.
卡蒂自七月起也一直负责 GPT-Infra 的运营，该项目使用 OpenAI 的模型进行诸如设计半导体之类的工作。该项目现已移交给公司芯片负责人理查德·霍，他本月表示，他并不完全信任这些模型的设计更改。
Katti had also run GPT-Infra since July, which uses OpenAI models for work such as designing semiconductors. That effort moves to Richard Ho, the company’s chip chief, who said this month he does not fully trust the models’ design changes.
“我为我们所建立的成果感到自豪，并对乌代及团队充满信心，”卡蒂说。他期待着打造一些全新的东西。
“I’m proud of what we’ve built and have total confidence in Uday and the team,” Katti said. He is looking forward to building something new.
鲁达拉朱继承的几乎全部是美国资产。OpenAI 于四月暂停了英国星门项目，理由是英国的电价超过美国水平的四倍以上，且版权规则尚未解决。
What Ruddarraju inherits is almost entirely American. OpenAI paused Stargate UK in April, citing British electricity prices more than four times US levels and unresolved copyright rules.
英国政府称这一决定令人失望。《卫报》后来报道称，OpenAI 从未访问过其在英格兰东北部宣布的项目所在地。
The UK government called the decision disappointing. The Guardian later reported that OpenAI had never visited the north-east England site it announced.
OpenAI 唯一公布的欧洲项目是位于挪威的 230 兆瓦数据中心，该项目于 2025 年 7 月被披露。仅俄亥俄州的规模就约为其 35 倍。向投资者展示的 8560 亿美元算力账单中的大部分将花费在跨大西洋地区。
OpenAI’s one announced European site is a 230-megawatt data centre in Norway, revealed in July 2025. Ohio alone is about 35 times larger. Most of the $856B compute bill shown to investors will be spent across the Atlantic.
