NVIDIA brings agents to life with DGX Spark and Reachy Mini

Today at CES 2026, NVIDIA demonstrated a system integrating the DGX Spark with the Reachy Mini robot, showcasing a functional AI agent capable of interacting with the physical world. The system leverages NVIDIA’s Nemotron reasoning LLMs and Isaac GR00T N1.6 open reasoning VLA, alongside the NVIDIA Cosmos world foundation models.

Why This Matters

Current AI assistants often operate in isolated digital environments, lacking the ability to meaningfully interact with the physical world. While ideal models promise seamless integration, the reality is complex and resource-intensive; deploying these models requires substantial compute and storage. This setup, requiring ~93GB of disk space for models, highlights the practical challenges of bringing advanced AI capabilities to a personal robotics platform, addressing a critical gap in current AI assistant technology.

Key Insights

• DGX Spark & Reachy Mini Demo: NVIDIA showcased a working agent at CES 2026.
• Composable Architecture: The system utilizes a modular approach, combining open models for reasoning and vision with an agent framework for orchestration.
• NeMo Agent Toolkit: NVIDIA’s NeMo Agent Toolkit enables flexible configuration and experimentation with different models and behaviors, and is used by developers to build agentic workflows.

Working Example

# Clone the repository
git clone git@github.com/brevdev/reachy-personal-assistant
cd reachy-personal-assistant

# Set up environment variables (example)
# Create a .env file with:
# NVIDIA_API_KEY=your_nvidia_api_key_here
# ELEVENLABS_API_KEY=your_elevenlabs_api_key_here

# Start the NeMo Agent Toolkit service
cd nat
uv venv
uv sync
uv run --env-file ../.env nat serve --config_file src/ces_tutorial/config.yml --port 8001

Practical Applications

• Personal Robotics: Enables users to create personalized AI assistants with physical embodiment for tasks like information retrieval and object manipulation.
• Developer Tooling: Provides a platform for developers to experiment with and build advanced agentic systems, leveraging open-source components and NVIDIA hardware.
