## AI overview

The article presents NVIDIA Labs Object-Oriented Agents (NOOA), a Python-based framework for building AI agents as single classes. It outlines six harness capabilities intended to improve model performance, including typed interfaces, live object references, code-based actions, programmable loops, explicit state, and model-callable APIs.
