arXiv:2605.21699v1 Announce Type: new Abstract: Cross-tokenizer knowledge distillation allows a student model to learn from teachers with incompatible vocabularies. Prior work operates on hidden states or logits; the latter is preferred as a drop-in replacement requiring no auxiliary components. Logit-based methods either use only the correct-token probability, missing the full 'dark knowledge' in the teacher's distribution, or operate on the full output distribution, relying on strict token partitioning and/or unprincipled heuristic ranking. We identify two key shortcomings of full-distributi
The proliferation of various AI models with diverse vocabularies necessitates more efficient knowledge transfer methods, especially as larger, more sophisticated models become specialized.
Improving knowledge distillation across incompatible AI models accelerates model refinement and allows more economic deployment of complex AI capabilities.
New methods for cross-tokenizer knowledge distillation will lead to more flexible and efficient training of specialized AI models.
