RainbowGPT provides a complete framework for designing, customizing, and deploying AI agents powered by OpenAI models. It includes a FastAPI backend, LangChain integration for tool and memory management, and a React-based UI for agent creation and testing. Users can upload documents for vector-based knowledge retrieval, define custom prompts and behaviors, and connect external APIs or functions. The platform logs interactions for analysis and supports multi-agent workflows, enabling complex automation and conversational pipelines.

Advanced_RAG provides a modular pipeline for retrieval-augmented generation tasks, including document loaders, vector index builders, and chain managers. Users can configure different vector databases (FAISS, Pinecone), customize retriever strategies (similarity search, hybrid search), and plug in any LLM to generate contextual answers. It also supports evaluation metrics and logging for performance tuning and is designed for scalability and extensibility in production environments.

This project demonstrates a comprehensive framework for creating retrieval-augmented AI agents using LlamaIndex. It guides developers through the entire workflow, starting with document ingestion and vector store creation, followed by defining a custom agent loop for contextual question-answering. Leveraging LlamaIndex's powerful indexing and retrieval capabilities, users can integrate any OpenAI-compatible language model, customize prompt templates, and manage conversation flows via a CLI interface. The modular architecture supports various data connectors, plugin extensions, and dynamic response customization, enabling rapid prototyping of enterprise-grade knowledge assistants, interactive chatbots, and research tools. This solution streamlines building domain-specific AI agents in Python, ensuring scalability, flexibility, and ease of integration.

At its core, Advanced RAG provides developers with a modular architecture to implement RAG workflows. The framework features pluggable components for document ingestion, chunking strategies, embedding generation, vector store persistence, and LLM invocation. This modularity allows users to mix-and-match embedding backends (OpenAI, HuggingFace, etc.) and vector databases (FAISS, Pinecone, Milvus). Advanced RAG also includes batching utilities, caching layers, and evaluation scripts for precision/recall metrics. By abstracting common RAG patterns, it reduces boilerplate code and accelerates experimentation, making it ideal for knowledge-based chatbots, enterprise search, and dynamic content summarization over large document corpora.
