NVIDIA Object-Oriented Agents (NOOA) is a model-agnostic Python framework that simplifies AI agent development by treating agents as native Python objects. In this approach, an agent's methods define executable actions, its fields represent state, docstrings serve as prompts, and type annotations act as contracts. A method with a body of "..." is completed at runtime by the model, eliminating the need for separate prompt templates, tool schemas, callback code, and workflow graphs. This unified, object-oriented paradigm aims to make agent construction more reliable and straightforward.
