Conversational-Ai

Roz answers questions about me in the visitor’s language, from what this website publishes and a set of notes written for her, with links to where each answer comes from. This is how she is designed: the idea behind her, her architecture, the search that decides what she reads, and the rules that keep her honest.

A conversational agent for e-commerce built with Ollama, LangChain, and ChromaDB, comparing three open-source LLMs — Qwen3 4B, Llama 3.2 3B, and Phi-4-mini — for product search, order tracking, recommendations, and RAG-powered FAQ. Benchmarks tool-calling accuracy, multi-intent handling, and response time across all three models.
