The Master Key Hypothesis: Unlocking Cross-Model Capability Transfer via Linear Subspace Alignment
Researchers propose the Master Key Hypothesis, suggesting that AI model capabilities can be transferred across different model scales without retraining through linear subspace alignment. The UNLOCK framework demonstrates training-free capability transfer, achieving significant accuracy improvements such as 12.1% gains on mathematical reasoning tasks when transferring from larger to smaller models.
