NVIDIA Generative AI Examples

Introduction

State-of-the-art Generative AI examples that are easy to deploy, test, and extend. All examples run on the high performance NVIDIA CUDA-X software stack and NVIDIA GPUs.

NVIDIA NGC

Generative AI Examples can use models and GPUs from the NVIDIA NGC: AI Development Catalog.

Retrieval Augmented Generation (RAG)

A RAG pipeline embeds multimodal data -- such as documents, images, and video -- into a database connected to a LLM. RAG lets users chat with their data!

Developer RAG Examples

The developer RAG examples run on a single VM. The examples demonstrate how to combine NVIDIA GPU acceleration with popular LLM programming frameworks using NVIDIA's open source connectors. The examples are easy to deploy with Docker Compose.

Examples support local and remote inference endpoints. If you have a GPU, you can inference locally with TensorRT-LLM. If you don't have a GPU, you can inference and embed remotely with NVIDIA API Catalog endpoints.

Enterprise RAG Examples

The enterprise RAG examples run as microservices distributed across multiple VMs and GPUs. These examples show how to orchestrate RAG pipelines with Kubernetes and deployed with Helm.

Enterprise RAG examples include a Kubernetes operator for LLM lifecycle management. It is compatible with the NVIDIA GPU operator that automates GPU discovery and lifecycle management in a Kubernetes cluster.

Enterprise RAG examples also support local and remote inference with TensorRT-LLM and NVIDIA API Catalog endpoints.
