AI Chatbot with RAG

LangChain + LangGraph

High-performance AI Chatbot with a dual-model architecture (Groq Llama 3.3 + Gemini 3.1 Flash-Lite), persistent RAG pipeline, and real-time streaming.

Developed using Next.js 15, FastAPI, and LangGraph with a dual-model architecture (Groq Llama 3.3 + Gemini 3.1 Flash-Lite).
Engineered a Persistent RAG Pipeline with FAISS and HuggingFace Embeddings (MiniLM) for deterministic document processing and context-aware chat memory across sessions.
Implemented real-time SSE (Server-Sent Events) streaming, optimized with React memoization and a Node.js proxy to handle high-frequency UI updates.
Integrated automated LLM fallback logic to maintain 100% uptime during API quota exhaustion, with stateful thread history managed via MongoDB.
