Researchers have developed a new framework called Budget-Efficient Thinking (BET) to optimize the computational resources used by large reasoning models (LRMs). Unlike previous methods that focused on perceived difficulty, BET treats adaptive reasoning as an investment under uncertainty, allocating budget based on expected return. This approach enables LRMs to answer easy queries concisely, abstain from unpromising lines of reasoning, and dedicate sufficient resources to challenging but solvable problems. Experiments across seven benchmarks and three base models demonstrated that BET can reduce reasoning tokens by 54% while improving accuracy by up to 3.2%. AI
IMPACT This framework could lead to more efficient deployment of large reasoning models, reducing operational costs and potentially improving response times.
