Revitalizing Black-Box Interpretability: Actionable Interpretability for LLMs via Proxy Models

Researchers propose a cost-effective proxy model framework that uses smaller, efficient models to approximate the interpretability explanations of expensive Large Language Models (LLMs), achieving over 90% fidelity at just 11% of computational cost. The framework includes verification mechanisms and demonstrates practical applications in prompt compression and data cleaning, making interpretability tools viable for real-world LLM development.

Predicting LLM Reasoning Performance with Small Proxy Model

Researchers introduce rBridge, a method that enables small AI models (≤1B parameters) to effectively predict the reasoning performance of much larger language models. This breakthrough could reduce dataset optimization costs by over 100x while maintaining strong correlation with large-model performance across reasoning benchmarks.

Can Small Training Runs Reliably Guide Data Curation? Rethinking Proxy-Model Practice

Researchers demonstrate that small-scale proxy models commonly used by AI companies to evaluate data curation strategies produce unreliable conclusions because optimal training configurations are data-dependent. They propose using reduced learning rates in proxy model training as a simple, cost-effective solution that better predicts full-scale model performance across diverse data recipes.
