Nvidia’s RTX Spark laptops, which launched on Friday, are built to run AI agents on the laptop itself. Users can install agents such as GitHub Copilot, Hermes, OpenClaw and Perplexity from the first start-up, without a command line, Nvidia said.
Each laptop runs on a single superchip that pairs a Blackwell RTX graphics chip with a Grace processor. It has up to 128GB of shared memory and up to 1 petaflop of AI performance. Nvidia says that lets the laptops run large language models and AI agents locally. MediaTek worked with Nvidia on the processor design.
“RTX Spark brings the power of NVIDIA AI, RTX graphics and CUDA together with Microsoft Windows in one PC for creating, gaming and running personal AI agents,” said Jensen Huang, Nvidia’s founder and chief executive.
“We’re building Windows to be the platform for hybrid intelligence, where AI can run locally when it makes sense and reach the cloud when needed,” said Yusuf Mehdi, executive vice president at Microsoft.

To run those agents, Nvidia released Nemotron 3.5 Bolt on Thursday. It has 74 billion parameters, with 9 billion active at a time, squeezed into 24GB of memory. Nvidia says it runs on supported RTX Spark configurations. Its weights, training data and recipes are open, and it works with llama.cpp, Ollama, LM Studio, Unsloth and vLLM.
