SFT on divergent branch-heavy CoT from DeepSeek-R1 yields worse generalization than convergent CoT from gpt-oss despite lower loss, but filtering frequent branches improves average performance by 3.6% on five reasoning benchmarks.
Reasoning in large output spaces proceeds via shortlisting then fine-grained reasoning; this characterization enables a mechanistic distillation strategy that outperforms standard distillation.
