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.
