- Satya Nadella opened Microsoft’s Build keynote by spotlighting Windows and unveiling the Surface RTX Spark Dev Kit, which he called a “dream machine.”
- RTX Spark chips for Windows on Arm, announced by Nvidia, can run a 120‑billion‑parameter large language model locally on creator‑focused laptops and miniature PCs slated for release later this year.
- Pavan Davuluri said Microsoft will build the best AI stack on Windows and the cloud, emphasizing a hybrid compute model where local RTX Spark handles workloads and offloads to the cloud when needed.
- Jensen Huang urged that PCs run AI locally to avoid cloud costs, suggesting users could “text” their laptop via WhatsApp for tasks.
Why it matters: Enterprises and developers gain cheaper, faster AI processing as RTX Spark enables 120‑billion‑parameter models on‑device, cutting cloud‑service fees and spurring a shift toward hybrid compute hardware later this year.
