Apple Machine Learning Research has introduced ARBITRAGE, a new framework designed to enhance the efficiency of large language models (LLMs) during reasoning tasks. Traditional speculative decoding methods often struggle with reasoning due to unnecessary rejections, even at the step level. ARBITRAGE addresses this by employing a dynamic routing system trained to predict when the target model will provide a significantly better reasoning step, approximating an ideal oracle for optimal efficiency-accuracy trade-offs. This approach has demonstrated up to a 2x reduction in inference latency on mathematical reasoning benchmarks while maintaining matched accuracy compared to existing step-level speculative decoding baselines.
