NVIDIA Releases 'NOOA', a Python Class-Based AI Agent Framework

NVIDIA Labs has released NOOA (NVIDIA-labs Object Oriented Agents), a Python framework for AI agent development. Unlike existing frameworks that separate prompts, tools, and callbacks into distinct abstractions, NOOA provides an object-oriented interface that integrates all these elements into a single Python class.

Core Design Principles

• Agents as Objects: Class fields define state, methods define capabilities, docstrings define prompts, and type annotations define contracts.
• Code Execution Model: Method bodies handled with ... become agentic loops executed by the LLM, while methods with actual code written behave as deterministic Python code.
• Type Safety: Supports typed input/output (I/O) and automatic retry features, allowing direct calls to Python methods by passing live objects by reference, without the need for separate tool schema definitions.

Installation and Configuration

It can be installed via uv or pip, with specific features such as CLI, memory management, and benchmarks separated into distinct packages. Classified as research software, it is recommended to run LLM-generated code in an OS-level isolation environment such as NVIDIA OpenShell.
