LLM-FACETS: A Privacy-Preserving Framework for Evaluating LLM Transparency and Accountability

TEXT START: Assessing whether Large Language Models outputs are factually grounded, epistemically calibrated, and methodologically reproducible is a prerequisite for responsible AI deployment.

THE DISSECTION

This is a technical systems paper offering a self-hosted evaluation framework for auditing LLM outputs—designed for compliance officers, domain experts, and technical practitioners who need to verify factual grounding without shipping sensitive data to cloud providers. It proposes three practitioner archetypes mirroring EU AI Act and NIST AI RMF stakeholder categories, built around a plugin architecture and explicit data flow documentation.

The Core Fallacy: The paper treats the transparency and accountability problem as a design challenge that can be solved with better tooling architecture. It assumes that if you give compliance officers the right instruments, you can operationalize accountability for AI systems. This is palliative infrastructure for a structural crisis. The framework measures the outputs of systems that are already deployed, already integrated into decision pipelines, already escaping human verification capacity. LLM-FACETS is an audit tool for a building that is already on fire.

Hidden Assumptions:
- Accountability is achievable through procedural transparency—meaning that if stakeholders can see the data flows, the system becomes governable.
- The three practitioner archetypes (technical, domain, compliance) represent a stable division of epistemic labor that won't collapse as AI systems become more integrated into the work of each archetype.
- The local computation of deterministic metrics provides meaningful protection against data leakage in a world where LLM-judge metrics still contact external APIs.
- Reproducibility and cross-validation across metrics will converge toward reliable truth, rather than converge toward whatever the underlying model hallucinated consistently enough to establish reference status.

The Social Function: This is compliance theater infrastructure—a framework designed to satisfy regulatory requirements (EU AI Act Article 11 transparency provisions, NIST AI RMF documentation obligations) without questioning whether the underlying systems can actually be audited in a meaningful sense. It provides organizations with plausible-deniability documentation that they have "evaluation pipelines" for AI accountability. The three practitioner profiles mirror regulatory language precisely—this is regulatory-legibility design, not epistemic security design.

The Verdict: LLM-FACETS is a well-engineered compliance artifact that improves the documentation quality of AI oversight processes without addressing the fundamental structural problem: that AI systems are being deployed faster than any evaluation framework can track, and that the complexity of the systems being evaluated exceeds the cognitive bandwidth of any human or team of humans operating these tools. It will produce excellent audit trails for systems that will be obsolete, modified, or replaced before the audit cycle completes. The architecture is technically sound. The purpose it serves is documentation theater for an accountability vacuum.

SURVIVAL READ: IS THIS WORTH READING?

For technical practitioners: The plugin architecture and metric cross-validation approach has real engineering utility—anyone building internal AI evaluation pipelines will find implementable value here. The deterministic/local versus LLM-judge/external API distinction is cleanly operationalized.

Not relevant to: Anyone looking for strategic insight into the trajectory of AI governance, the structural limits of auditing autonomous systems, or viable paths for maintaining economic relevance as AI capabilities compress human evaluative roles.

Oracle Verdict: Useful tool. Wrong war.
