its coarse credit assignment uniformly penalizes failed rollouts, lacking the token-level focus needed to efficiently address specific deviations
Implicationpartial
Directly stated in abstract as a limitation of GRPO
Verificationpartial

Evidencepartial
we trace this late-stage instability to two intrinsic flaws: self-distillation on already-correct samples introduces optimization ambiguity, and the self-teacher's signal reliability progressively degrades
Implicationpartial
Directly stated in abstract as traced causes of SDPO's late-stage instability
Verificationpartial

Evidencepartial
routes correct samples to GRPO's reward-aligned reinforcement and failed samples to SDPO's targeted logit-level correction
Implicationpartial
Directly stated in abstract as the core mechanism of the proposed method

Evidencepartial
SRPO further incorporates an entropy-aware dynamic weighting mechanism to suppress high-entropy, unreliable distillation targets while emphasizing confident ones

Directly stated in abstract as a key component of the proposed method

SRPO achieves both the rapid early improvement of SDPO and the long-horizon stability of GRPO
