--- title: "Retail Shopping Assistant" publisher: "nvidia" type: "blueprint" updated: "2026-02-17T19:31:28.303Z" description: "Elevate Shopping Experiences Online and In Stores." canonical: "https://build.nvidia.com/nvidia/retail-shopping-assistant" --- AI-powered shopping assistants give retailers a new way to engage customers — intelligently, personally, and at any hour across any market. Today's shoppers expect more than keyword search. They arrive with complex, open-ended needs: outfitting a backyard, planning a themed birthday party, or finding the right combination of products for a project they can barely describe. Existing tools fall short here — built for short, structured queries, they leave customers empty-handed and retailers without a sale. Every failed search is a missed opportunity to convert, upsell, or build loyalty. This NVIDIA AI Blueprint gives retailers a production-ready reference for deploying a shopping assistant that understands natural language and images, handles multi-step discovery, and delivers personalized, context-aware recommendations — driving higher conversion rates, larger order sizes, and fewer returns. ## Architecture Diagram ![Architecture Diagram](https://assets.ngc.nvidia.com/products/api-catalog/retail-shopping-assistant/diagram.jpg) ## Key Features * An end-to-end sample multimodal, multi-query agentic pipeline with image-aware query routing and image-to-image similarity search via NVClip, enabling consumers to use text and images together in natural queries * Optimized LLM inference performance and scaling through NIM microservices, bringing advanced reasoning capabilities for natural, humanlike interactions * Intelligent cart management with natural language add, remove, and update commands — including persistent price tracking and pronoun resolution across multi-turn conversations * Language-agnostic product matching with catalog-derived vocabulary, making the assistant portable across non-English retail catalogs without additional configuration * Guardrails that keep customer conversations safe and on-topic through dual NeMo Guard NIM microservices for content safety and topic control, protecting brand values * High accuracy product discovery and data privacy powered by NVIDIA Retrieval QA E5 Embedding v5 * Integration with LangChain and the NVIDIA cuVS GPU-accelerated Milvus vector database * Sample retail product catalog and imagery with the ability to ingest retailers' own product catalog text and image data for accurate, context-aware responses * Production-ready test infrastructure with unit and integration coverage across all services and CI/CD workflows for automated validation * The flexibility to use other models from the NVIDIA API catalog or self-hosted models ![Screenshot image](https://assets.ngc.nvidia.com/products/api-catalog/retail-shopping-assistant/screenshot1.jpg) ## Minimum System Requirements ### Hardware Requirements * 4 x H100 (Locally hosted models) ### Deployment Options * Docker ## Software Used in This Blueprint **NVIDIA Technology** * [NVIDIA Retrieval QA E5 Embedding v5](https://build.nvidia.com/nvidia/nv-embedqa-e5-v5) * [NVclip](https://build.nvidia.com/nvidia/nvclip) * [Nemotron 3 super 120b a12b NIM](https://build.nvidia.com/nvidia/nemotron-3-super-120b-a12b) * [Llama 3.1 Nemoguard 8B Topic Control](https://build.nvidia.com/nvidia/llama-3_1-nemoguard-8b-topic-control) * [Llama 3.1 Nemoguard 8B Content Safety](https://build.nvidia.com/nvidia/llama-3_1-nemoguard-8b-content-safety) **3rd Party Software** * [LangChain](https://www.langchain.com/) * Milvus database (accelerated with NVIDIA [**cuVS**](https://github.com/rapidsai/cuvs)) * SQLite ## Ethical Considerations NVIDIA believes Trustworthy AI is a shared responsibility, and we have established policies and practices to enable development for a wide array of AI applications.
