Running cost uses real token math — agent runs × tokens per run × current provider list prices, plus vector DB, hosting, and observability tiers. Token-per-run figures come from typical chat (~1.5k), RAG (~7k), and agentic (~30k) workloads. Build cost reflects real freelance engagement scope (foundation + the components you select).
