RTX Spark Laptops Enable Local 284B AI Models That Rival GPT-5
Microsoft and NVIDIA announced that RTX Spark-powered laptops can run 284-billion-parameter AI models locally, matching GPT-5 performance in coding and reasoning. The Surface Laptop Ultra, priced from $2,599, features up to 128GB unified memory to support these dense models without cloud reliance. Windows 11 now includes Microsoft Execution Containers for secure agent management, while new hybrid intelligence features allow Copilot to use local context and models. Preorders for RTX Spark devices from multiple OEMs begin October 16, 2026, with compact desktops following in November.
