Projects use Retrieval Augmented Generation Rag

Retrieval-Augmented Generation grounds LLM answers in external knowledge by retrieving relevant chunks and injecting them into the prompt. Projects cover ingestion, chunking, embeddings, vector stores, retrieval strategies, generation and evaluation (faithfulness, relevance).

Tools used widely: LangChain, LlamaIndex, FAISS, Chroma, Pinecone, Hugging Face, OpenAI/local LLMs, Haystack, RAGAS and Streamlit/Gradio demos.
