Basic Information

This repository is a curated collection of examples, tutorials, starter code, and ready applications for building generative AI projects that use vector databases and retrieval-augmented generation. It is centered on LanceDB, a free, open-source, serverless vector database that the README describes as requiring no setup and integrating with the Python data ecosystem. The repo organizes recipes into sections such as Build from Scratch, Multimodal, RAG, Vector Search, Chatbot, Evaluation, AI Agents, Recommender Systems, and Concepts. It provides interactive notebooks, scripts, and example apps in Python and Node that demonstrate patterns for ingestion, embeddings, vector search, hybrid search, reranking, and agentic workflows. The content is aimed at engineers and researchers who want runnable examples and applied guidance to prototype PoCs and productionizable GenAI components using LanceDB.

App Details

Features
Contains dozens of categorized, hands-on examples and applications covering RAG pipelines, multimodal search, vector search patterns, chatbots, evaluation tools, recommender systems, and agent workflows. Provides interactive notebooks and Colab-ready demonstrations, Python scripts, and Node/TypeScript examples that leverage LanceDB along with common tooling such as LangChain, LlamaIndex, LangGraph, and various embedding and reranking techniques. Includes applied projects like multimodal video/image search, FinTech agent examples, Streamlit RAG evaluation app, deployable website chatbot templates, and production-oriented Node apps. Highlights serverless usage of LanceDB, integration with pandas/Arrow/Pydantic, a native TypeScript SDK, and instructional content on chunking, compression, fine-tuning with PEFT/QLoRA, and optimization strategies.
Use Cases
Helps developers and data practitioners accelerate development of GenAI systems by offering ready-made patterns and runnable code for common problems such as document retrieval, context enrichment, hybrid search, multimodal indexing, and agent collaboration. The recipes make it faster to build PoCs and iterate by supplying example pipelines, deployment-ready app templates, and evaluation tools for measuring RAG quality. It lowers operational friction by demonstrating LanceDB usage that requires no infrastructure setup and by showing integrations into existing Python and Node toolchains. The collection is useful for learning retrieval strategies, testing rerankers and compression schemes, exploring agentic designs, and adapting sample apps for production features like TTS, geospatial recommenders, and multilingual RAG.
