Researchers have developed DART, a novel training-free framework for hybrid reasoning models. DART optimizes token usage by adaptively routing queries to either direct answering or extended thinking processes. The system achieves this by sampling two low-cost drafts and comparing them; agreement leads to direct answering, while disagreement triggers a budget prediction based on draft entropy. This approach maintains or enhances accuracy while significantly reducing token consumption, showing promise across various model scales and families without requiring labeled data or gradient updates.
