  1. CRISP: Compressed Reasoning via Iterative Self-Policy Distillation (2026 · 17 citations)
    Reasoning models often produce very long chains of thought, even for simple problems. This raises inference cost and can introduce mistakes. CRISP shortens reasoning without labelled answers, length budgets or difficulty estimators. The model acts as its own teacher: the same network, given an extra instruction to be…
  2. TIP: Token Importance in On-Policy Distillation (2026 · 17 citations)
    On-policy distillation (OPD) trains a student model on sequences it generates itself, with the teacher giving feedback at every token.
