Interactive guide
The Intelligence Stack
This guide maps the broader architectural shift in AI from chatbots to agents, orchestrators, and software that behaves more like an operating layer.
It is useful if you want the big-picture frame for why recent changes in models, tools, and interfaces matter. The question is not only whether the models are better. It is what kind of system AI is becoming.
What this guide maps
The page follows the move from early scripted chat systems to modern large language models, then into tool use, multi-agent coordination, and workflow-level orchestration. That arc explains why AI increasingly feels less like a single feature and more like a layer spread across software.
Why architecture matters
Model quality still matters, but architecture explains more of the practical difference between a chatbot, an assistant, an agent, and a broader operating layer. That is the level where workflows, tools, memory, and autonomy start to connect.
