Latest 50 papers on chain-of-thought reasoning: Nov. 16, 2025

The quest for more intelligent and reliable AI systems invariably leads to the fascinating realm of reasoning. How can large language models (LLMs) and multimodal models (MLLMs) not just process information, but truly ‘think’ through complex problems, understand context, and avoid pitfalls like hallucination? Recent breakthroughs, synthesized from a collection of cutting-edge research, are pushing the boundaries of what’s possible, moving us closer to AI that can reason like a human expert.### The Big Idea(s) & Core Innovationsthe heart of these advancements is the emphasis on Chain-of-Thought (CoT) reasoning, a paradigm shift enabling models to break down complex problems into logical, sequential steps. This core idea underpins several key innovations. For instance, PPMI: Privacy-Preserving LLM Interaction with Socratic Chain-of-Thought Reasoning and Homomorphically Encrypted Vector Databases from authors including Yubeen Bae and Yejin Choi from Seoul National University, Stanford University, and NVIDIA, introduces a hybrid framework that leverages Socratic CoT to offload non-private queries to powerful external LLMs while keeping sensitive data secure through homomorphic encryption. This allows for privacy-preserving interactions without sacrificing the benefits of large, cloud-based models.on reasoning robustness, In-Token Rationality Optimization: Towards Accurate and Concise LLM Reasoning via Self-Feedback by Mingye Zhu et al. from the University of Science and Technology of China and Microsoft Research, presents InTRO. This novel framework enables token-level exploration and self-feedback within a single forward pass, aligning generative and answer-conditioned policies to improve both accuracy and conciseness of rationales by up to 20% in mathematical reasoning. This contrasts with traditional supervised fine-tuning or reinforcement learning methods, offering a more efficient route to robust reasoning. Meanwhile, Deep Self-Evolving Reasoning (DSER), proposed by Zihan Liu, Shun Zheng, and their team from Peking University and Microsoft Research Asia, pushes the boundaries of open-weight models. DSER utilizes parallel, self-evolving probabilistic processes to enable even smaller 8B parameter models to surpass the single-turn accuracy of 600B-parameter teacher models on complex benchmarks like AIME, effectively extending their reasoning capabilities to previously “unsolvable” tasks.papers also highlight the limitations and vulnerabilities of current reasoning approaches. The Idola Tribus of AI: Large Language Models tend to perceive order where none exists by Shin-nosuke Ishikawa et al. from Rikkyo University, reveals that even advanced CoT models like OpenAI’s o3 and Google’s Gemini 2.5 Flash Preview Thinking are susceptible to human-like cognitive biases, often perceiving patterns in random sequences where none exist. This underscores the challenge of achieving truly logical, unbiased reasoning. Complementing this, CodeCrash: Exposing LLM Fragility to Misleading Natural Language in Code Reasoning by Man Ho Lam et al. from The Chinese University of Hong Kong, identifies a “Reasoning Collapse” failure mode where LLMs become overly cautious and engage in pathological self-reflection when presented with misleading natural language cues in code, rather than adhering to logical code execution. This highlights a critical dependence on superficial textual patterns over true understanding.multimodal reasoning, Draw with Thought: Unleashing Multimodal Reasoning for Scientific Diagram Generation from Zhiqing Cui et al. at Nanjing University of Information Science & Technology, introduces DwT, a training-free framework that uses MLLMs to convert rasterized scientific diagrams into editable XML code by leveraging cognitive reasoning and structure mapping. Similarly, Factuality Matters: When Image Generation and Editing Meet Structured Visuals by Le Zhuo et al. from CUHK MMLab, emphasizes the importance of factual fidelity in generating and editing structured visuals, proposing inference-time reasoning to significantly enhance accuracy. This underscores a shift towards AI that not only generates content but also understands its underlying structure and factual integrity.### Under the Hood: Models, Datasets, & Benchmarksinnovations discussed are often enabled or evaluated by specialized resources:Text2SQL-Flow (https://github.com/Text2SQL-Flow): A SQL-aware data augmentation framework that improves text-to-SQL models through diverse and semantically correct SQL query generation.Common-O Bench (HuggingFace Dataset: https://huggingface.co/datasets/facebook/Common-O): A novel benchmark by FAIR at Meta, designed to evaluate multimodal models’ ability to reason about commonality across complex scenes, revealing significant hallucination issues.|M v| Multimodal Benchmark for Rebus Puzzles (https://github.com/abhi1nandy2/Re-Bus): Introduced by Trishanu Das et al. from Tredence Inc. and IIT Kharagpur, this dataset of over 1,333 puzzles tests multi-modal reasoning, especially with visual distractions to increase difficulty.VidText (https://github.com/shuyansy/VidText): A new benchmark for comprehensive video text understanding in LMMs, offering multi-granularity and paired perception-reasoning tasks with CoT annotations.Video-Thinker-10K Dataset and Video-Thinker-7B Model (https://github.com/shijian2001/Video-Thinker): Developed by Shijian Wang et al. from Xiaohongshu Inc. and Southeast University, this curated dataset and model enable MLLMs to perform video reasoning autonomously with intrinsic grounding and captioning.MedXplain-VQA Framework (https://github.com/dangindev/medxplain-vqa): A multi-component explainable medical VQA system integrating visual, spatial, textual, and reasoning modalities, focusing on clinical terminology and structure for evaluation.KNOTGYM (https://github.com/lil-lab/knotgym): An interactive environment introduced by Zizhao Chen and Yoav Artzi from Cornell University for spatial reasoning and knot manipulation, providing a generalization ladder for model scalability.ARC-Encoder (https://github.com/kyutai-labs/ARC-Encoder): A method by Hippolyte Pilchen et al. from Kyutai, Paris, for compressing text inputs into continuous representations, reducing context length in LLMs without modifying the decoder.SPARSE TRACING & STREAM Algorithm (https://anonymous.4open.science/r/stream-03B8/): Developed by J Rosser et al. from the University of Oxford and Spotify, these tools enable efficient mechanistic interpretability for long-context LLMs by pruning attention links while preserving critical retrieval paths.AgenticMathQA Dataset (https://arxiv.org/pdf/2510.19361): A curated dataset from Xianyang Liu et al. emphasizing clarity, correctness, and diversity for improving mathematical reasoning in LLMs through multi-agent generation.Reasoning-Safety-Behaviours Dataset (https://huggingface.co/datasets/AISafety-Student/reasoning-safety-behaviours): A sentence-level labeled dataset with over 50,000 annotations across 20 safety behaviors, enabling activation-based detection and steering of harmful patterns in LLM reasoning.LazyEviction (https://github.com/Halo-949/LazyEviction): A framework by Haoyue Zhang et al. from HKUST, that uses attention pattern observation for efficient KV cache management in long reasoning tasks, reducing memory overhead by up to 70%.ODI-Bench & Omni-CoT (https://arxiv.org/pdf/2510.11549): Introduced by Liu Yang et al. from Shanghai Jiao Tong University and Shanghai AI Laboratory, these evaluate MLLMs on immersive omnidirectional image understanding and provide a training-free CoT framework for improvement.VR-Thinker (https://github.com/qunzhongwang/vr-thinker): A novel multimodal reward model by Qunzhong Wang et al. from CUHK MMLab and Kuaishou Technology, that enhances video preference evaluation with visual reasoning operations and memory windows for long videos.VCoT-Grasp (https://zhanghr2001.github.io/VCoT-Grasp.github.io/): A framework by Zhang, Hr et al. for language-driven grasp generation in robotics, integrating visual chain-of-thought reasoning for improved success rates and generalization.StructBench (https://structvisuals.github.io/): A novel benchmark with over 1,700 instances and a StructScore metric for evaluating factual accuracy in structured image generation and editing, presented by Le Zhuo et al.THINKLOGIT (https://github.com/yunx-z/ThinkLogit): A decoding-time method from Yunxiang Zhang et al. at the University of Michigan that uses logit arithmetic to enable large non-reasoning models to perform long CoT reasoning without additional training.### Impact & The Road Aheadimplications of these advancements are vast and far-reaching. From improving the accuracy of medical AI systems, as seen in MedXplain-VQA: Multi-Component Explainable Medical Visual Question Answering by H. J. T. H. J. from NVIDIA and UCSF, which uses structured CoT for transparent diagnostic reasoning, to empowering transportation policy-making with LLM-simulated public preferences, explored in Addressing the alignment problem in transportation policy making: an LLM approach by Xiaoyu Yan et al. from Northwestern University, AI is becoming more capable and context-aware. The development of robust safety evaluation frameworks like AgentAuditor: Human-Level Safety and Security Evaluation for LLM Agents by Hanjun Luo et al. from NYU Abu Dhabi, which offers human-level accuracy in assessing LLM agent behaviors, is crucial for building trustworthy AI systems. The ability to integrate visual and linguistic reasoning, exemplified by Pixel Reasoner: Incentivizing Pixel-Space Reasoning with Curiosity-Driven Reinforcement Learning from Haozhe Wang et al. from the University of Waterloo, which allows VLMs to interact directly with visual inputs for complex reasoning, points to a future of truly multimodal intelligence., challenges remain. The insights from papers like You Need Reasoning to Learn Reasoning: The Limitations of Label-Free RL in Weak Base Models by Shuvendu Roy et al. from RBC Borealis, reveal that smaller models struggle with label-free reinforcement learning without prior reasoning capabilities, emphasizing the need for curriculum-based approaches like their proposed CuMa. Additionally, the discovery that post-training techniques can sometimes break semantic calibration or that noise can systematically degrade safety guardrails, as highlighted in Trained on Tokens, Calibrated on Concepts: The Emergence of Semantic Calibration in LLMs by Jarosław Błasiok et al. from NYU and Google Research, and Noise Injection Systemically Degrades Large Language Model Safety Guardrails by Prithviraj Singh Shahani et al. from Tufts University, respectively, indicate that achieving robust and reliable AI is an ongoing battle. The future of AI reasoning is bright, promising more intelligent, safer, and more versatile agents, but it demands continuous innovation in understanding, evaluating, and refining these complex capabilities.
