This paper introduces AIGen, a modular generator for AI Bills of Materials (AIBoMs) that automates the documentation of AI system components in compliance with the SPDX 3.0 AI profile. By integrating with the MLflow MLOps framework and leveraging mining heuristics alongside Large Language Models, AIGen produces machine-readable inventories that can be customized through a plugin interface for various AI frameworks. The tool aims to enhance compliance with emerging regulations like the EU AI Act and the NIST AI Risk Management Framework, thus promoting transparency and accountability in AI supply chain governance.
AIGen automates the generation of AI Bills of Materials, making compliance with new AI regulations not just feasible but efficient.
The responsible development and deployment of artificial intelligence (AI) systems requires rigorous documentation of their constituent artifacts, e.g., datasets, model weights, training pipelines, and runtime dependencies. Although the Software Package Data Exchange (SPDX) 3.0 standard introduced native support for AI and dataset profiles, practical tooling capable of generating standards-compliant AI Bills of Materials (AIBoMs) in an automated and extensible manner remains scarce. This paper presents AIGen, a modular AIBoM generator that produces machine-readable, interoperable inventories of AI system components that comply with the SPDX 3.0 AI profile. AIGen works on top of the MLflow MLOps framework and combines mining heuristics with Large Language Models to generate AIBoMs. A plugin interface allows practitioners to extend the tool with domain-specific collectors without modifying the core codebase, supporting heterogeneous AI frameworks such as Hugging Face, PyTorch, and TensorFlow. AIGen is designed to facilitate compliance with the European Union AI Act, the NIST AI Risk Management Framework, and ISO/IEC 42001, providing a concrete, reusable foundation for transparent, accountable AI supply chain governance.
