Data Flywheel

This tutorial demonstrates an end-to-end Data Flywheel implementation that uses NVIDIA NeMo Microservices. It features a tool-calling workflow with the NVIDIA NeMo Datastore, NeMo Entity Store, NeMo Customizer, NeMo Evaluator, NeMo Guardrails microservices, and NVIDIA NIMs.

• Tool Calling Fine-tuning, Inference, and Evaluation with NVIDIA NeMo Microservices and NIMs

Knowledge Graph RAG

This example implements a GPU-accelerated pipeline for creating and querying knowledge graphs using RAG by leveraging NIM microservices and the RAPIDS ecosystem to process large-scale datasets efficiently.

• Knowledge Graphs for RAG with NVIDIA AI Foundation Models and Endpoints

Agentic Workflows with Llama 3.1

• Build an Agentic RAG Pipeline with Llama 3.1 and NVIDIA NeMo Retriever NIM microservices [Blog, Notebook]
• NVIDIA Morpheus, NIM microservices, and RAG pipelines integrated to create LLM-based agent pipelines

RAG with Local NIM Deployment and LangChain

Vision NIM Workflows

A collection of Jupyter notebooks, sample code and reference applications built with Vision NIMs.

To pull the vision NIM workflows, clone this repository recursively:

git clone https://github.com/nvidia/GenerativeAIExamples --recurse-submodules

The workflows will then be located at GenerativeAIExamples/vision_workflows

Data Flywheel

A Data Flywheel is a self-reinforcing cycle where user interactions generate data that improves AI models or products, leading to better outcomes that attract more users and further enhance data quality. This feedback loop relies on continuous data processing, model refinement, and guardrails to ensure accuracy and compliance while compounding value over time. Real-world applications range from personalized customer experiences to operational systems like inventory management, where improved predictions drive efficiency and growth.

Tool-Calling Notebooks

Tool calling empowers Large Language Models (LLMs) to integrate with external APIs, execute dynamic workflows, and retrieve real-time data beyond their training scope. The NVIDIA NeMo microservices platform offers a modular infrastructure for deploying AI pipelines that includes fine-tuning, evaluation, inference, and guardrail enforcement—across Kubernetes clusters in cloud or on-premises environments.

This end-to-end tutorial demonstrates how to leverage NeMo Microservices to customize Llama-3.2-1B-Instruct by using the xLAM function-calling dataset, assess its accuracy, and implement safety constraints to govern its behavior.

RAG

RAG Notebooks

NVIDIA has first-class support for popular generative AI developer frameworks like LangChain, LlamaIndex, and Haystack. These end-to-end notebooks show how to integrate NIM microservices using your preferred generative AI development framework.
