This paper tests that assumption directly. It measures how much each extra 500 reasoning tokens adds to accuracy. Two open-weight 32B models, DeepSeek-R1-32B and s1-32B, are run under budget forcing at 32 budgets from 500 to… 2. **[DynamicFocalPO: Adaptive Focusing Strategy for Preference Optimization](https://md.research.elamur.ai/free/en/papers/zhou-2026-dynamicfocalpo-adaptive-focusing-strategy-preference/)** *(2026)* Preference optimization methods such as DPO align LLMs on pairs of preferred and rejected answers. However, they are easily disturbed by pairs that the model initially ranks the wrong way. FocalPO reduces the influence of such pairs with a modulating factor p^γ, but it keeps γ constant for the entire run.
