Overview

• Researchers introduce L2S-Merge, a method that combines long-reasoning and short-reasoning models
• The technique outperforms both individual models by merging their complementary strengths
• Achieved 28% performance increase over short-reasoning models, with 3× faster inference
• Creates a single unified model that adapts to different reasoning needs
• Works across various model architectures and reasoning tasks
• Uses task vectors rather than full models for efficient merging

Plain English Explanation

Have you ever noticed how some people solve problems in different ways? Some take a methodical step-by-step approach, carefully reasoning through each stage, while others seem to "just know" the answer through intuition. Both approaches have their place, depending on the comple...
