arXiv:2606.05988v1 Announce Type: cross Abstract: Reasoning models produce long chain-of-thought traces that are costly to distill and encourage verbose student outputs. We study post-hoc compression of such traces before knowledge distillation. Two teachers, Qwen3.5-397B-A17B and gpt-oss-120B, generate about 283k correct traces each; two instruction-tuned models then compress them to 8.6-21.0% of their original character length. Across a 48-run main grid plus seven Qwen-teacher truncation ablations, compressed traces reduce training tokens to 12-30% of raw, speed up training by 2.0-7.6x, and
Ongoing advancements in large language models necessitate more efficient training and deployment methods, making trace compression a timely area of research.
This development significantly reduces the computational cost of knowledge distillation and training, making powerful AI models more accessible and efficient to develop.
The process of knowledge distillation becomes considerably faster and less resource-intensive, potentially accelerating AI model development cycles.
