Idea
Alignment framework improving open-source LLM responses for intent accuracy without fine-tuning or retraining.
Research Paper
Core Innovation
This paper introduces SDA, a novel training-free method that dynamically redistributes output probabilities of open-source LLMs based on user-defined instructions during inference. Unlike prior fine-tuning approaches, SDA achieves significant alignment improvements across multiple models and dimensions without additional training or supervision.
Why It Matters
Ensuring LLMs produce responses aligned with human intent is critical for real-world applications but retraining is costly and slow. SDA offers a lightweight, inference-time solution that enhances model alignment efficiently, enabling broader adoption and customization across industries. This reduces deployment barriers and improves user trust and satisfaction.
Market Size (TAM)
$10–20B TAM for AI model alignment and deployment tools; $2–5B SAM from enterprises and AI developers. Driven by growing LLM adoption and demand for safe, aligned AI.
