1. $0 to run. It ships with a fallback chain of seven free OpenRouter models. Every other kit either charges you monthly or pushes you onto a paid API from day one. This one costs $19 once and then nothing. 2. No frameworks. No LangChain, no vector database, no embeddings, no agent orchestration layer that breaks every six months. It's 400 lines of plain Python with requests and json. You can read the whole thing in 20 minutes.
