Pivot-SD: Efficient Self-Distillation for Masked Diffusion Language Models
arXiv cs.AI · Published · 3 min read
In 30 seconds
- What happened
- Pivot-SD is a self-distillation method that trains masked diffusion language models by focusing on high-impact token commitments during denoising rather than full sequences.
- Why it matters
- Relevant for engineers optimizing masked diffusion models for reasoning tasks, especially when training data or compute budgets are constrained.
- Watch out
- Results shown only on LLaDA-8B with 200 questions and four rollouts each; generalization to larger models or different architectures remains unclear.
