Generative AI Chatbot Projects — From LLM to Conversation

Generative AI chatbots use large language models to produce free-form, multi-turn responses — often grounded with retrieval (RAG) or tools. Final-year projects that implement fine-tuning, RAG pipelines, agents or safety layers with clear evaluation metrics produce strong, portfolio-ready results.

Below are 80+ topics across fine-tuning, RAG chatbots, agents, prompting, safety and applications, with tools (LangChain, Hugging Face, LlamaIndex, PEFT/LoRA) and dialogue/FAQ datasets.
