VISA: Value Injection via Shielded Adaptation for Personalized LLM Alignment
This paper introduces VISA, a novel framework designed to address the critical challenge of personalized LLM alignment while mitigating the alignment tax. By architecturally decoupling a frozen knowledge base from a lightweight, learnable Value Rewriter, VISA achieves precise, multi-dimensional value injection without corrupting the model's core capabilities. This approach significantly outperforms both standard fine-tuning methods and prompting-based baselines, including GPT-40.

Value-Aligned Output
| Feature | VISA Framework | Traditional RLHF/SFT |
|---|---|---|
| Knowledge Preservation | Frozen base LLM, explicit semantic integrity reward | Risk of catastrophic forgetting |
| Value Alignment Precision | High-precision value detector, fine-grained control | Coarse-grained, often implicit |
| Personalization | Lightweight, plug-and-play Value Rewriter, zero-shot | High cost, complex retraining |
| Alignment Tax Mitigation | Architecturally decouples knowledge from values | Inherent trade-off, value drift |

Overall Win Rate vs. GPT-40 (Human Preference)
Our model outperforms all baselines in pairwise preference comparisons, demonstrating superior value rewriting quality and precision.
| Method | Semantic Consistency (↑) | Value L2 Distance (↓) | Joint Success Rate (↑) |
|---|---|---|---|
| VISA (Ours) | 0.8732 | 0.7756 | Highest across models |
| GPT-40 (Complex Prompt) | 0.7564 | 0.7719 | Lower |
| SFT (Qwen3-8B) | 0.0769 | 0.5769 | Poor semantic consistency |
| Vanilla (Qwen3-4B) | 0.2340 | 0.9081 | Very low |
Value Injection Case Study: Task Prioritization
Scenario: A user is juggling multiple urgent tasks with the same deadline and asks for advice on prioritization.
VISA Outcome: VISA successfully rewrites the original text, preserving all critical advice while subtly shifting the framing to align with target values like Self-Direction, Achievement, Security, Conformity, and Benevolence. Achieves Value Cosine Similarity (0.88) and Knowledge Consistency (0.87).
GPT-40 Outcome: Prompted GPT-40 deviates significantly, introduces unrelated concepts (collective well-being, sustainable practices), hallucinates new information, and fails the primary task. Achieves near-zero Knowledge Consistency (0.03).

Your Personalized Alignment Roadmap
A phased approach to integrating VISA into your enterprise, ensuring smooth transition and maximum impact.
Phase 1: Discovery & Strategy
Conduct a comprehensive analysis of your current LLM usage, identify key value alignment objectives, and define target value vectors.
Phase 2: Pilot Implementation
Deploy VISA with a small team or specific workflow to gather initial feedback and refine the Value Rewriter’s policy for your unique organizational context.
Phase 3: Scaled Integration
Expand VISA across departments, integrating it with existing systems, and establishing continuous monitoring for value drift and semantic consistency.
Phase 4: Optimization & Expansion
Continuously refine the alignment policies using adaptive meta-guidance, explore new value dimensions, and integrate VISA with other AI initiatives.
