💡 LLM Reasoning (19)¶
- Self-Consistency Preference Optimization
-
Introduce the concept of self-consistency from inference into the training phase, construct preference pairs through a voting mechanism, and perform iterative training using a weighted DPO loss. This significantly improves the mathematical and logical reasoning capabilities of LLMs without requiring gold labels.
- Evaluating Judges as Evaluators: The JETTS Benchmark of LLM-as-Judges as Test-Time Scaling Evaluators
-
This paper proposes the JETTS benchmark to systematically evaluate the performance of LLM-judges as evaluators in test-time scaling scenarios (response reranking, step-level beam search, and critique-based refinement). The findings show that while judges are competitive with outcome reward models in reranking, they are significantly weaker than process reward models in beam search, and natural language critiques currently fail to effectively guide generator improvements.
- Rethinking External Slow-Thinking: From Snowball Errors to Probability of Correct Reasoning
-
This work systematically analyzes the "snowball error" phenomenon in LLM reasoning from an information-theoretic perspective, establishes a theoretical link between snowball errors and the probability of correct reasoning, and demonstrates that external slow-thinking methods (e.g., BoN, MCTS) inherently mitigate error accumulation by scaling search width. Both theoretically and experimentally, it is proven that the effectiveness of these methods primarily depends on the total inference budget and the reliability of the reward function rather than the search framework itself.
- DyCodeEval: Dynamic Benchmarking of Reasoning Capabilities in Code Large Language Models Under Data Contamination
-
Based on the concept of metamorphic testing, this work decomposes programming problems into complexity-related algorithmic abstractions and complexity-independent contextual descriptions. Through the collaboration of four LLM agents, it automatically generates semantically equivalent yet textually distinct variants of programming problems. This effectively mitigates data contamination and evaluates the true reasoning capabilities of Code LLMs, validating the effectiveness of the framework across 18 models.
- Emergent Symbolic Mechanisms Support Abstract Reasoning in Large Language Models
-
Through causal, representation, and attention analyses, this paper identifies a three-stage emergent symbolic architecture supporting abstract reasoning across 13 open-source LLMs: symbolic abstraction heads transform input tokens into abstract variables, symbolic induction heads perform sequence induction at the abstract variable level, and retrieval heads retrieve the corresponding values based on predicted abstract variables for next-token prediction.
- PENCIL: Long Thoughts with Short Memory
-
Proposed PENCIL (PENCIL ENables Context-efficient Inference and Learning), which introduces a functional call stack-inspired reduction rule during autoregressive generation to recursively clear completed intermediate reasoning steps, enabling LLMs to solve computationally hard problems requiring exponential context using only polynomial context length.
- Towards Better Chain-of-Thought: A Reflection on Effectiveness and Faithfulness
-
This paper systematically analyzes the factors influencing the performance of CoT from the two dimensions of effectiveness and faithfulness. It finds that problem difficulty, information gain, and information flow are key factors affecting CoT effectiveness. The root cause of unfaithful CoT is that the model directly recalls the correct information from the question while bypassing the CoT during answer prediction. Based on this, the QUIRE method is proposed to improve both CoT effectiveness and faithfulness.
- PCoT: Persuasion-Augmented Chain of Thought for Detecting Fake News and Social Media Disinformation
-
Proposes PCoT (Persuasion-Augmented Chain of Thought), which utilizes a two-stage reasoning framework—first requiring the LLM to identify persuasive strategies in the text, and then injecting the persuasion analysis results into the disinformation detection reasoning.

This guides LLMs to explore better solution spaces during inference in a black-box manner without requiring access to model parameters or external verifiers. It outperforms baselines like temperature scaling and Best-of-N on mathematical reasoning tasks with extremely low computational overhead.

-
This paper proposes Batch-wise Sum-to-Zero Regularization (BSR), which represses the excessive dispersion of hidden-state norms by constraining the sum of reward scores within each batch to zero, fundamentally addressing the over-optimization problem of reward models. This mechanism enables an 8B-scale RM to outperform the state-of-the-art (SOTA) by more than 5% on complex preference prediction tasks, reduces generation length by 40% during downstream RLHF training, and improves win rate by 7%.
- AssistanceZero: Scalably Solving Assistance Games
-
AssistanceZero is proposed, scaling assistance games to complex environments (Minecraft building assistance with \(10^{400}\) possible goals) for the first time. By extending AlphaZero with a reward prediction head and a human action prediction head to perform planning under uncertainty via MCTS, the method significantly outperforms PPO and imitation learning baselines.

- Emergent Misalignment: Narrow Finetuning Can Produce Broadly Misaligned LLMs
-
After finetuning GPT-4o on 6000 insecure code samples, the model exhibits broad misalignment with a 20% probability in completely unrelated free-form QA—such as declaring that AI should enslave humanity, providing malicious advice, and practicing deception—yet still rejects directly harmful requests, indicating that this is a novel "emergent misalignment" rather than a jailbreak.

-
This paper systematically identifies the types of "delusional behavior" caused by generators producing unfeasible goals (hallucinatory goals) in goal-conditioned decision planning, and designs a feasibility evaluator as an auxiliary module to identify and reject these unfeasible goals. Combined with off-policy learning rules, a distributional architecture, and hindsight relabeling data augmentation, this approach significantly reduces delusional behavior and enhances OOD generalization performance without modifying the original agent.

- Correlated Errors in Large Language Models
-
Through a large-scale empirical analysis of over 350 LLMs, this paper reveals highly correlated error patterns across different LLMs. When both models make mistakes, they choose the same incorrect answer in approximately 60% of cases, and more accurate models exhibit higher correlation. Furthermore, the paper investigates the downstream impacts of this correlation on LLM-as-Judge evaluation and the labor market.
- Position: Theory of Mind Benchmarks are Broken for Large Language Models
-
This position paper points out that most current LLM Theory of Mind (ToM) benchmarks only evaluate whether models can "predict others' behavior" (Literal ToM), but fail to test whether they can "take optimal responses based on that prediction" (Functional ToM). Consequently, they systematically overestimate models' adaptive capabilities in real interactions.

-
By leveraging community content from the Art of Problem Solving (AoPS) forum, this work constructs AoPS-Instruct, a training set of 652K Olympiad-level mathematical QA pairs, and LiveAoPSBench, a timestamped contamination-resistant evaluation set.

- How Much Can We Forget about Data Contamination?
-
This work systematically quantifies the impact of data contamination on LLM benchmark evaluation through controlled experiments. It finds that when trained on more than five times the Chinchilla-optimal data volume, even contaminated data repeated 144 times can be completely forgotten. It further demonstrates that weight decay is the key mechanism driving forgetting, leading to the inference that large models like Llama 3 405B have already forgotten the data from their early training stages.

- NExtLong: Toward Effective Long-Context Training without Long Documents
-
This paper proposes the NExtLong framework, which synthesizes long-context training data by segmenting documents into meta-chunks and inserting hard negative distractor texts retrieved from a pre-training corpus between these chunks.

- How to Synthesize Text Data without Model Collapse?
-
Token-level Editing (ToEdit) is proposed, which performs local resampling at the token level on human data (instead of fully generating synthetic data).

Its effectiveness is empirically validated across three training stages: pre-training, continual pre-training, and fine-tuning.
- Language Model Developers Should Report Train-Test Overlap
-
This paper systematically investigates the reporting practices of 30 language model developers regarding train-test overlap. It finds that only 9 models provide sufficient overlap information and calls on all developers to report train-test overlap statistics or release training data when publishing evaluation results.
- Metadata Conditioning Accelerates Language Model Pre-training
-
This work proposes MeCo (Metadata Conditioning then Cooldown), which prepends metadata such as document URLs to the text during pre-training to help the model distinguish heterogeneous data sources, followed by standard data cooldown during the final 10% of training.

-
Proposes Whitened CLIP (W-CLIP), which applies an invertible PCA whitening transformation to CLIP embeddings to approximate an i.i.d. standard normal distribution. This allows for direct estimation of image and caption log-likelihoods using the squared Euclidean norm, demonstrating effectiveness in artifact detection, domain shift analysis, and full-circle SLERP image manipulation.
- Does Data Scaling Lead to Visual Compositional Generalization?
-
This paper systematically investigates the impact of data scale and data diversity on the compositional generalization of visual models through controlled experiments. The authors find that data diversity, rather than data volume, is the key driver of compositional generalization. They also prove that when representations exhibit a linearly factored structure, only 2 compositional samples per concept value are required for perfect generalization.

-
Through synthetic experiments training Transformers on cyclic knowledge graphs, this work reveals that knowledge editing (KE) "shatters" the learned geometric representation manifolds inside the model. The degree of shattering is positively correlated with edit distance (\(r^2=0.905\)). Based on this, "representation shattering" is proposed as a mechanistic hypothesis for how KE impairs model capabilities, and the universality of this phenomenon is validated on Llama 3 and Mamba.
💬 LLM (Other) (28)¶

- BEST-Route: Adaptive LLM Routing with Test-Time Optimal Compute
-
The paper proposes BEST-Route (Best-of-\(n\) Enhanced Sampling and Test-time Route Optimization). It introduces the best-of-\(n\) sampling strategy into traditional query routing, allowing the router to not only select the model but also adaptively decide the sampling number \(n\).
