who_is_this_for: This is an advanced topic for developers who want to build a Retrieval-Augmented Generation (RAG) pipeline on the NVIDIA DGX Spark platform. You'll learn how Arm-based Grace CPUs handle document retrieval and orchestration, while Blackwell GPUs speed up large language model inference using the open-source llama.cpp REST server. This is a great fit if you're interested in combining Arm CPU management with GPU-accelerated AI workloads.

This demo showcases a fully offline voice assistant that combines real-time transcription (via faster-whisper) and intelligent response generation (via vLLM). Running on an Arm-based DGX Spark system, the assistant captures live audio, transcribes it, and generates context-aware replies using a local language model, all in a seamless loop.
