How UtilityHub Categorizes AI Architecture

Rather than classifying projects solely by their marketing labels, UtilityHub evaluates the core execution model: whether state is cyclic (LangGraph/ReAct), conversational (AutoGen), protocol-isolated (FastMCP), or streaming (Voice/WebSockets). This helps developers find architectures that match their exact engineering constraints.
