Revolutionizing LLM Inference: A Multi-Dimensional Quality Scoring Framework
This paper introduces a multi-dimensional quality scoring framework for decentralized LLM inference, addressing the critical challenge of assessing output quality reliably and incentive-compatibly. It decomposes quality into modular dimensions like model priors, structure, semantics, and alignment, enabling systematic auditing and calibration. The framework integrates with Proof of Quality (PoQ) mechanisms to ensure robust reward allocation and adversarial resilience. Key findings include the task-dependence of certain quality dimensions and the necessity of calibration to prevent negative correlations, ultimately yielding a calibrated composite score that outperforms single evaluators and consensus baselines.

Reliability of Dimensions
Semantic quality is consistently informative (Pearson correlation with GT: 0.733). However, intuitive dimensions like query-output alignment and agreement/uncertainty can be unreliable or even negatively correlated if not calibrated. This highlights the risk of naive aggregation.

Impact of Calibration on QA vs. Summarization
Problem: Unreliable dimensions like alignment and agreement can degrade composite score alignment, especially in task-dependent scenarios.
Solution: Systematic reliability auditing and task-wise calibration, including removing negatively correlated dimensions, is crucial.
Outcome: Calibrated composite scores significantly outperform default configurations and individual evaluators in specific tasks, improving Pearson correlation on QA by over 15 percentage points.
In QA tasks, alignment and agreement dimensions show strong negative correlation with GT (e.g., -0.571 Pearson for alignment). After calibration (removing these), the composite Pearson correlation with GT improves from 0.742 to 0.893. In summarization, these dimensions are weakly positive, showing task dependence.

Your Implementation Roadmap
A structured approach to integrate multi-dimensional quality scoring and PoQ into your enterprise LLM operations.
Phase 1: Initial Framework Deployment & Baseline Auditing
Deploy the multi-dimensional scoring framework with default weights. Conduct initial reliability auditing of each dimension against reference signals. Identify task-dependent dimensions and potential negative correlations. (2-4 Weeks)
Phase 2: Task-Specific Calibration & Weight Optimization
Based on auditing results, perform task-wise calibration. This involves re-normalizing weights for informative dimensions and potentially disabling unreliable ones. Optimize composite score for alignment with enterprise objectives. (4-6 Weeks)
Phase 3: PoQ Integration & Robustness Testing
Integrate the calibrated composite score as the quality signal into your PoQ aggregation and reward mechanisms. Conduct robustness testing against various adversarial attacks and evaluator heterogeneity to ensure incentive alignment. (3-5 Weeks)
Phase 4: Continuous Monitoring & Adaptive Trust
Implement continuous monitoring of dimension reliability, distribution shifts, and evaluator behavior. Deploy adaptive trust weighting mechanisms to dynamically adjust for inconsistent evaluators and maintain long-term system integrity. (Ongoing)
