NVIDIA brings agents to life with DGX Spark and Reachy Mini

At CES 2026, NVIDIA introduced a series of open models and tools designed to help developers create AI agents capable of real-world interaction, including the NVIDIA Nemotron reasoning LLMs and NVIDIA Isaac GR00T N1.6 VLA. These tools, combined with the NVIDIA DGX Spark processing power and Reachy Mini robot, enable the creation of personalized AI assistants that can process data privately and interact with users naturally. The blog post outlines a comprehensive guide for building such an assistant, detailing the integration of reasoning, vision, and text-to-speech models using the NeMo Agent Toolkit, which facilitates the orchestration of various AI components. The setup allows for local or cloud deployment, offering flexibility in how the AI agent is hosted and managed. The system's modular design ensures the ability to swap models, adapt routing logic, and add new functionalities, providing a customizable and open alternative to traditional personal assistants.
