  1. LLM-as-a-Judge & Reward Model: What They Can and Cannot Do (2024 · 27 citations)
    Automated evaluators, meaning LLM-as-a-Judge setups and reward models (RMs), increasingly replace human raters when scoring long-form LLM outputs and guiding RL-based alignment.
  2. Linguistic Generalizability of Test-Time Scaling in Mathematical Reasoning (2025 · 24 citations)
    The paper asks whether test-time scaling methods, which spend extra compute at inference, help mathematical reasoning across many languages as they do in English.
  3. Pushing on Multilingual Reasoning Models with Language-Mixed Chain-of-Thought (2025 · 7 citations)
    Most open work on distilling long chain-of-thought reasoning into smaller models targets English or Chinese.
