1. Why do some LMs self-improve their reasoning while others hit a wall. Four key cognitive behaviors enable successful learning: Verification (checking work), Backtracking (trying new approaches), Subgoal Setting, and Backward Chaining (working backwards from a goal). https://arxiv.org/abs/2503.01307

2. A Three-Layer Model of LLM Psychology https://www.lesswrong.com/posts/zuXo9imNKYspu9HGv/a-three-layer-model-of-llm-psychology

3. Chain of Draft: Thinking Faster by Writing Less—80% fewer tokens per response yet maintains accuracy on math, commonsense, and other benchmarks. On GSM8k math problems, CoD achieved 91% accuracy with an 80% token reduction compared to CoT. https://arxiv.org/abs/2502.18600

4. Reasoning models will enable superhuman capabilities in “pure reasoning tasks” such as mathematics and abstract problem-solving https://epoch.ai/gradient-updates/the-promise-of-reasoning-models

5. SoS1: O1 and R1-Like Reasoning LLMs are Sum-of-Square Solvers — “Our findings highlight the potential of LLMs to push the boundaries of mathematical reasoning and tackle NP-hard problems.” https://arxiv.org/abs/2502.20545

6. LeanProgress: Guiding Search for Neural Theorem Proving via Proof Progress Prediction https://arxiv.org/abs/2502.17925
