labs OO Agents
labs OO Agents is an open source Python framework that builds AI agents using an object-oriented interface.
NVIDIA-labs Object Oriented Agents is a model-agnostic Python framework designed to support reliable AI agent development. It offers an object-oriented interface that brings separate abstractions like prompts, tools, callbacks, and workflows together inside a single Python class. Fields represent state, methods represent capabilities, docstrings act as prompts, and type annotations serve as contracts. The model acts by writing Python in a Jupyter-style REPL with access to self, imports, and helpers. It supports familiar Python testing, tracing, refactoring, and version-control workflows.
