AI Cost & Decision Calculators

Shipping AI features means living with token bills, agent loops, retrieval costs and compliance exposure you can't eyeball. These interactive calculators turn those unknowns into numbers — model your real LLM spend, find the break-even between self-hosting and APIs, price a RAG stack, and size your regulatory risk before it reaches production. Built for developers, architects and AI engineering leads.
