OpenAI 在俄亥俄州的 8GW 投资重塑 AI 基础设施竞赛
OpenAI said it has agreed to secure approximately 8 gigawatts of IT capacity at the PORTS-Pike Technology Campus in southern Ohio. SB Energy will build, own, and operate the site under a 20-year lease; the first 800 megawatts are expected in 2028. OpenAI says the campus will exclusively host Nvidia compute.
NVIDIA 为俄亥俄州 8GW AI 园区提供支持
NVIDIA agreed to support SB Energy's PORTS-Pike campus in Ohio, where OpenAI will lease the initial 4.25GW of IT capacity for 20 years and deploy NVIDIA's DSX platform. An SEC filing caps NVIDIA's aggregate obligation under the initial residual-value guarantees at $105 billion. NVIDIA can support another roughly 3.8GW, while the partners plan at least 10GW of new generation and phased service beginning in 2028.
Google 将手语 AI 从研究项目带到 Pixel
Google DeepMind introduced SL2T, a multilingual sign-language-to-text model trained on more than 100,000 hours across over 50 sign languages. The model now powers ASL-to-English dictation in Gboard and Live Transcribe on Pixel 11, letting users sign searches, messages, documents, and Gemini requests. An on-device tracker converts video into pose landmarks and discards the original footage before sending coordinates for server-side translation.
AI 基础设施支出推动 Nebius 营收跃升
Nebius reported second-quarter revenue of $582.3 million, up 454% from a year earlier, and adjusted EBITDA of $236.2 million. The Nasdaq-listed AI infrastructure company also disclosed $5.66 billion of quarterly purchases of property, equipment, and intangible assets, illustrating how aggressively it is adding capacity. Cash and equivalents stood at $8.04 billion at quarter-end, while the company recorded a $190.4 million loss from continuing operations.
NVIDIA 将 AI 算力变成 5000 亿美元融资市场
NVIDIA signed memorandums of understanding with Apollo, BlackRock, Blackstone, Brookfield, Goldman Sachs, and KKR to create independent financing platforms for AI infrastructure. The partners aim to mobilize more than $500 billion of third-party capital over time, building dedicated pools that can finance NVIDIA-based compute for frontier labs, enterprises, and AI clouds. The arrangements remain subject to final agreements.
AI 需求重塑英特尔资本计划，公司转向 150 亿美元股票出售
Intel announced a $15 billion underwritten common-stock offering and may let underwriters buy another $2.25 billion of shares. The chipmaker said proceeds could support capital expenditures and working capital while protecting its investment-grade rating. Intel tied the timing to sustained customer demand for AI compute and cited physical AI, purpose-built silicon, advanced packaging, and external wafer manufacturing as growth opportunities.
网络能力接近关键阈值，OpenAI 暂停 Astra 工作
OpenAI said preliminary internal evaluations of its upcoming Astra model show enough progress in agentic coding and cybersecurity that the company cannot rule out the Critical threshold under its Preparedness Framework. OpenAI paused internal Astra activities that do not meet strengthened controls, including isolated test environments, restricted network and tool access, stronger weight protection, universal monitoring of agentic applications, and expanded testing with government agencies and safety organizations.
AMD AI 引擎推动数据中心营收突破 67 亿美元
AMD reported $11.5 billion in second-quarter revenue, up 50% from a year earlier, while its Data Center segment reached $6.7 billion, a 107% increase. The company attributed the segment's growth to demand for EPYC processors and Instinct MI350 GPUs. Data Center operating income rose to $2.1 billion from a $155 million loss a year ago, when export-control-related inventory charges weighed on results.
Volta 的 100 亿美元算力交易抬高新云竞争门槛
New AI cloud company Volta has signed a six-year strategic compute partnership worth $10 billion for a 133-megawatt deployment in Norway. Investor Andreessen Horowitz disclosed the contract while announcing its participation in Volta's $300 million financing; Bloomberg identified the customer as Anthropic. The deployment will use infrastructure associated with Bitdeer's Tydal site, giving the young provider an unusually large anchor workload from the outset.
