Overview

OWASP AIBOM Generator is an open source tool that takes a Hugging Face model ID as input, fetches model card metadata, and generates an AI SBOM in CycloneDX format. It is maintained by the OWASP Gen AI Security Project, and its distinguishing feature is scoring how complete the generated BOM is.

Where cdxgen identifies dependencies quickly but leaves the license fields empty, this tool fills in the license, author, and external references recorded in the model card. It works well as a starting point for the license review required by3.5 License Obligations.

Key Features

• Fetches metadata from Hugging Face models and generates an AIBOM in both CycloneDX 1.6 and 1.7 format.
• Evaluates the completeness of the generated BOM with a score (0–100) and a profile, broken down section by section.
• Displays model information, the model card, license, and external references in a human-readable view.
• Available both as a web UI and a command-line interface (CLI).

Usage A — Web UI

The simplest approach: just enter a model ID in the browser. Use the Hugging Face Space provided by the OWASP Gen AI Security Project, or clone the repository and run it locally.

First, enter a Hugging Face model ID (e.g.,facebook/bart-large-cnn) on the input screen and click generate.

Once generation finishes, the result screen shows an AIBOM summary, the completeness assessment, download buttons (CycloneDX 1.6 and 1.7), AI model information, and the model card. The completeness assessment at the top of the screen shows at a glance whether the BOM has the minimum fields needed for identification.

The result screen offers a Human-Friendly View along with a field checklist, a score report, and a JSON view tab. Check the items needed for license obligation review and AI SBOM retention directly on screen, and download the CycloneDX file.

Usage B — Command Line (CLI)

The CLI is convenient for embedding in CI/CD or batch-processing multiple models. After installation, pass the model ID as an argument.

# Install (a Python virtual environment is recommended)pip install"git+https://github.com/GenAI-Security-Project/aibom-generator"# Generate an AIBOM from a model IDaibom facebook/bart-large-cnn -o aibom.json

Below is the actual execution result. It generates CycloneDX 1.6 and 1.7, passes schema validation, and shows the completeness score broken down by section.

$ aibom facebook/bart-large-cnn -o aibom.json✅ Successfully generated CycloneDX 1.6 SBOM — Schema Validation (1.6): Valid✅ Successfully generated CycloneDX 1.7 SBOM — Schema Validation (1.7): Valid📊 Completeness Score: 58.7/100 Profile: Basic - Required Fields: 20/20 - Metadata: 8/20 - Component Basic: 17.1/20 - Component Model Card: 6.7/30 - External References: 10/10

Figure 3. CLI execution output(aibom CLI, model facebook/bart-large-cnn, run 2026-06-13)

The model component in the generated BOM has its license and model card filled in. Unlike cdxgen’s output, thelicenses field is not empty.

{"type":"machine-learning-model","name":"bart-large-cnn","purl":"pkg:huggingface/facebook/bart-large-cnn","licenses":[{"license":{"id":"MIT"}}],"authors":[{"name":"facebook"}],"modelCard":{"modelParameters":{},"considerations":{}}}
