Proprietary Components
The following components are not covered by the CC license:
- Custom software tools and modules
- Platform integrations and APIs
- Implementation findings and best practices
Commercial Licensing
The full commercial software platform is available for commercial use under a yearly paid license.
Legal Disclaimer
Not Legal Advice
The vfairness library and the AI Fairness Assessment and Interventions Platform are technical tools for measuring statistical properties of machine learning models. The metrics, thresholds, and recommendations provided by this software do not constitute legal advice regarding compliance with anti-discrimination laws, regulations, or standards.
User Responsibility
Users are solely responsible for:
- Determining the appropriateness of fairness metrics for their specific use case
- Setting thresholds that meet their legal and regulatory requirements
- Interpreting results in the context of their domain and jurisdiction
- Consulting with qualified legal counsel regarding compliance obligations
No Warranty of Fairness
Passing fairness metrics computed by vfairness or the platform does not guarantee that a system is "fair" in any legal, ethical, or common-sense meaning of the term. Fairness is a complex, context-dependent concept that cannot be fully captured by any set of statistical measures.
Regulatory Compliance
References to regulations (EU AI Act, EEOC guidelines, etc.) in this documentation are for informational purposes only. Regulatory requirements vary by jurisdiction and are subject to change. Users should verify current requirements with appropriate authorities.
AI-Assisted Development Disclosure
AI-Assisted Development
In the spirit of transparency, we disclose that this project has been developed with the assistance of AI-powered coding tools. The development team has utilized the following AI technologies:
AI pair programming assistant for code completion and suggestions
Primary AI assistant for code generation, documentation, and architecture
Agentic coding assistant for complex implementation tasks
AI system for code generation and natural language to code translation
Human Oversight Statement
Most of the AI-generated code and documentation has been reviewed, tested, and validated by human developers. Given the complexity and breadth of the library, the development team cannot maintain full responsibility for:
- Architectural decisions and system design
- Code review and quality assurance
- Security auditing and vulnerability assessment
- Testing, validation, and verification
- Final approval of all committed code
Why We Disclose This
As a project focused on AI fairness and transparency, we believe in practicing the transparency we advocate. AI-assisted development tools are becoming standard in software engineering, and we choose to openly acknowledge their role in our development process. This disclosure reflects our commitment to honest communication about how modern software is built.
