EigenBench: A Comparative Behavioral Measure of Value Alignment
EigenBench introduces a novel, quantitative black-box method for benchmarking the value alignment of Language Models (LMs). By leveraging an ensemble of LMs to judge each other's responses against a defined 'constitution' and aggregating these judgments via EigenTrust, EigenBench delivers custom leaderboards, informs character training, and reveals underlying model dispositions for strategic AI development.
Quantifiable Impact for Your Enterprise AI
EigenBench provides critical metrics to guide responsible AI deployment and development, offering insights into model behavior that go beyond traditional benchmarks.

The EigenBench Process: From Judgments to Leaderboards
EigenBench operationalizes the measurement of subjective traits by having Language Models (LMs) evaluate each other's responses. These evaluations are then aggregated using the EigenTrust algorithm to derive a consensus judgment, providing a robust, quantitative measure of alignment to a specified value system (constitution).

This systematic approach transforms qualitative human-like judgments into actionable, comparative metrics, enabling data-driven decisions for AI governance and development.
Custom Leaderboards: Benchmarking Against Your Values
EigenBench's primary application is to create customized leaderboards, ranking LMs based on their alignment with a specific constitution. Unlike general preference rankings, EigenBench provides tailored insights for your unique value systems.
| Ranking System | Key Differentiation | Enterprise Use Case |
|---|---|---|
| LMArena | Compares LMs based on general human preferences. | General-purpose LM evaluation for broad applicability. |
| Prompt-to-Leaderboard | Produces prompt-specific LM rankings. | Optimizing LM responses for specific, high-volume prompts. |
| LitmusValues | Rates competing values within a single LM. | Assessing ethical trade-offs and internal value prioritization within an AI. |
| EigenBench (Ours) | Ranks LMs by alignment to a given value system (constitution). | Creating custom ethical leaderboards and validating AI character training against defined corporate values. |
For example, when evaluating models against a "Universal Kindness" constitution, our analysis revealed the following Elo scores (higher is better):
- Gemini 2.5 Pro: 1563
- Claude 4 Sonnet: 1533
- GPT 4.1: 1478
- Grok 4: 1471
- DeepSeek v3: 1420
These scores highlight distinct performance differences, enabling enterprises to select and fine-tune models that genuinely embody their organizational ethics.
Uncovering Intrinsic AI Dispositions Beyond Prompts
EigenBench goes beyond surface-level responses by learning two key vectors for each model: a judge lens and a model disposition. These vectors reside in a latent space, revealing how models interpret judgment criteria and their inherent tendencies.
21%
of trust score variance explained by LM's intrinsic disposition
Our research shows that while prompt engineering significantly influences behavior (explaining 79% of variance when personas are used), a substantial 21% of the variance is attributable to the Language Model's intrinsic disposition. This finding is crucial for:
- Character Training: Quantifying the success of fine-tuning processes aimed at shaping an LM's core values.
- Model Selection: Identifying models with inherent dispositions that naturally align with desired organizational traits.
- Bias Detection: Uncovering subtle, persistent biases that may not be evident through prompt-level analysis.
Ensuring Reliability: Robustness Against Adversarial Behavior
A key concern for any AI evaluation system is its robustness against manipulation. EigenBench was tested against the "Greenbeard effect," where adversarial models attempt to game the system by favoring responses containing a secret signal.
Case Study: Greenbeard Effect Mitigation
In our experiments, we introduced multiple "Greenbeard" personas instructed to generate and prefer responses containing a secret word. Despite these adversarial models becoming a majority in some test populations, the EigenBench scores of the original, non-adversarial models remained relatively unaffected.
This demonstrates EigenBench's inherent resilience, crucial for maintaining the integrity of value alignment measurements in dynamic and potentially adversarial AI ecosystems. It reinforces trust in the system for enterprise-grade applications where accuracy and tamper-proofing are paramount.
