An SBoM for an AI application catalogs every component: base models, fine-tuned checkpoints, libraries (e.g., PyTorch, Transformers), training datasets, and inference dependencies. This digital provenance creates transparency, allowing you to trace the origin of every part of your system. Without an SBoM, you cannot effectively manage vulnerabilities, comply with regulations like the EU AI Act, or audit your AI supply chain for risks like poisoned data or compromised models.

Setting Up a Software Bill of Materials (SBoM) for AI Applications
A practical guide to generating a comprehensive SBoM for AI applications. Learn to inventory models, datasets, and dependencies using Syft, format with SPDX/CycloneDX, and automate security scans with Grype in your CI/CD pipeline.
INTRODUCTION
Setting Up a Software Bill of Materials (SBoM) for AI Applications
A Software Bill of Materials (SBoM) is a formal, machine-readable inventory of all components in a software application. For AI systems, this is critical for security, compliance, and operational integrity.
You generate an SBoM by integrating automated tools like Syft and Grype into your CI/CD pipeline. These tools scan container images and directories to identify components, which are then formatted into standard schemas like SPDX or CycloneDX. The final SBoM is a JSON or XML file that can be shared with partners, fed into GRC workflows, or used to trigger security scans when new vulnerabilities are disclosed, forming the foundation for a provenance-aware AI development platform.
SBoM FUNDAMENTALS
Key Concepts: AI-Specific SBoM Components
A Software Bill of Materials for an AI application must catalog unique components beyond traditional software, including models, data, and specialized dependencies. This is the foundation for supply chain security and compliance.
PREREQUISITES
Step 1: Install SBoM Tooling (Syft & Grype)
This step installs the core tools for generating and analyzing a Software Bill of Materials (SBoM), establishing the foundation for AI supply chain security.
A Software Bill of Materials (SBoM) is a formal, machine-readable inventory of all components in your application. For AI systems, this includes base models, fine-tuned checkpoints, Python libraries, and system dependencies. We use Syft to generate the SBoM and Grype to scan it for known vulnerabilities. This duo automates the creation of a provenance-aware component list, which is critical for compliance and security audits under frameworks like the EU AI Act.
Installation is straightforward via package managers. For Linux/macOS, use the install scripts. For containerized environments, pull the Docker images. Verify the install by running syft version and grype version. These tools will form the core of your automated SBoM pipeline, which you will later integrate into CI/CD as part of your broader MLOps and Model Lifecycle Management for Agents.

Common Mistakes
Generating a Software Bill of Materials (SBoM) is a foundational step for AI supply chain security, but developers often stumble on the same pitfalls. This guide addresses the most frequent errors and provides clear solutions to ensure your SBoM is accurate, actionable, and integrated.
Standard software SBoM tools often fail to recognize AI-specific artifacts. An SBoM must include all components that constitute your application's "supply chain," which for AI extends beyond libraries to:
- Base and fine-tuned model checkpoints (e.g.,
.safetensors,.binfiles) - Training and validation datasets
- Configuration files (e.g.,
adapter_config.jsonfor LoRA) - Inference server dependencies (e.g., vLLM, TensorRT)
How to fix it: Use AI-aware SBoM generators. Tools like Anchore Syft can be extended with custom catalogers, or you can use spdx-sbom-generator with a pre-scan script to hash model files. The key is to explicitly define and scan the directories containing these non-standard artifacts.
