New method estimates black-box LLM uncertainty with lightweight proxy model

By PulseAugur Editorial · Summary by gemini-2.5-flash-lite from 2 sources

Researchers have developed a new method called Distribution-Aligned Adversarial Distillation (DisAAD) to estimate the uncertainty of black-box Large Language Models (LLMs). This technique uses a generation-discrimination architecture to train a smaller proxy model that learns the output distribution of the larger LLM. The proxy model can then reproduce responses and estimate uncertainty, even when it is only 1% the size of the original LLM. AI
