New CurioSFT method enhances large reasoning model exploration

By PulseAugur Editorial · [1 sources] · 2026-07-15 04:00

Researchers have developed CurioSFT, a novel supervised fine-tuning method for large reasoning models that aims to preserve exploration capabilities. Unlike standard SFT, which can lead to overconfidence and reduced diversity, CurioSFT uses self-exploratory distillation and adaptive temperature selection to encourage exploration without knowledge forgetting. Experiments show CurioSFT improves performance on in-distribution and out-of-distribution tasks during the SFT phase, and these preserved exploration capabilities translate to significant gains in subsequent reinforcement learning stages.

Entropy-Preserving Supervised Fine-Tuning via Adaptive Self-Distillation for Large Reasoning Models

arXiv:2602.02244v3 Announce Type: replace-cross Abstract: The standard post-training recipe for large reasoning models, supervised fine-tuning followed by reinforcement learning (SFT-then-RL), may limit the benefits of the RL stage: while SFT imitates expert demonstrations, it of…
