Week 11: 3 LLM Architecture Patterns for Production AI

It seems that much of the public conversation around large language models remains focused on the single-turn assistant. You ask a question, you get an answer. It’s a useful paradigm, but it’s also a limiting one for anyone trying to build durable, valuable systems.

The most interesting work we’re seeing isn’t happening inside the prompt window. It’s happening at the architectural level, where the LLM is treated not as a destination, but as a component within a larger system.

We are observing three distinct architectural patterns emerge as teams move from simple experiments to production applications.

The first is the LLM-as-a-Controller. In this model, the LLM’s primary job is not to answer a question, but to interpret a...
