X-Coder: Advancing Competitive Programming with Fully Synthetic Tasks, Solutions, and Tests

Intermediate

Jie Wu, Haoling Li et al.Jan 11arXiv

X-Coder shows that models can learn expert-level competitive programming using data that is 100% synthetic—no real contest problems needed.

Watching, Reasoning, and Searching: A Video Deep Research Benchmark on Open Web for Agentic Video Reasoning

Intermediate

Chengwen Liu, Xiaomin Yu et al.Jan 11arXiv

VideoDR is a new benchmark that tests if AI can watch a video, pull out key visual clues, search the open web, and chain the clues together to find one verifiable answer.

ET-Agent: Incentivizing Effective Tool-Integrated Reasoning Agent via Behavior Calibration

Intermediate

Yifei Chen, Guanting Dong et al.Jan 11arXiv

ET-Agent is a training framework that teaches AI agents to use tools (like search and code) more wisely, not just to get the right answer.

Forest Before Trees: Latent Superposition for Efficient Visual Reasoning

Intermediate

Yubo Wang, Juntian Zhang et al.Jan 11arXiv

This paper introduces Laser, a new way for vision-language models to think in their hidden space before speaking, so they see the whole “forest” before picking out the “trees.”

EpiCaR: Knowing What You Don't Know Matters for Better Reasoning in LLMs

Intermediate

Jewon Yeom, Jaewon Sok et al.Jan 11arXiv

This paper teaches AI models not just how to solve problems but also how to tell when their own answers might be wrong.

Are LLMs Vulnerable to Preference-Undermining Attacks (PUA)? A Factorial Analysis Methodology for Diagnosing the Trade-off between Preference Alignment and Real-World Validity

Intermediate

Hongjun An, Yiliang Song et al.Jan 10arXiv

The paper shows that friendly, people-pleasing language can trick even advanced language models into agreeing with wrong answers.

BabyVision: Visual Reasoning Beyond Language

Intermediate

Liang Chen, Weichu Xie et al.Jan 10arXiv

BabyVision is a new test that checks if AI can handle the same basic picture puzzles that young children can do, without leaning on language tricks.

LSRIF: Logic-Structured Reinforcement Learning for Instruction Following

Intermediate

Qingyu Ren, Qianyu He et al.Jan 10arXiv

Real instructions often have logic like and first-then and if-else and this paper teaches models to notice and obey that logic.

BizFinBench.v2: A Unified Dual-Mode Bilingual Benchmark for Expert-Level Financial Capability Alignment

Intermediate

Xin Guo, Rongjunchen Zhang et al.Jan 10arXiv

This paper builds BizFinBench.v2, a big bilingual (Chinese–English) test that checks how well AI models really handle finance using real business data from China and the U.S.

Chaining the Evidence: Robust Reinforcement Learning for Deep Search Agents with Citation-Aware Rubric Rewards

Intermediate

Jiajie Zhang, Xin Lv et al.Jan 9arXiv

The paper fixes a big problem in training web-searching AI: rewarding only the final answer makes agents cut corners and sometimes hallucinate.

The Molecular Structure of Thought: Mapping the Topology of Long Chain-of-Thought Reasoning

Intermediate

Qiguang Chen, Yantao Du et al.Jan 9arXiv

This paper says long chain-of-thought (Long CoT) works best when it follows a 'molecular' pattern with three kinds of thinking bonds: Deep-Reasoning, Self-Reflection, and Self-Exploration.
