Researchers introduce Beaver, an AI agent harness designed to extract structured information from scientific papers containing multimodal evidence (text, tables, figures). The system achieves 81.0 on the Gold-Referenced Attribute Score, outperforming frontier agents by 23 points, demonstrating that harness design—not just underlying models—is critical for complex information extraction tasks.
A comprehensive study evaluates multimodal Chain-of-Thought reasoning across 12 tasks, revealing that CoT improves reasoning capabilities but degrades perception tasks and exhibits a "Look Light, Think Heavy" pattern where visual reflection diminishes during reasoning. The research demonstrates CoT should be applied selectively rather than universally, with existing open-source multimodal models showing only marginal improvements over baseline approaches.
Researchers demonstrate that visual shortcuts in vision-language models trained with reinforcement learning emerge sharply and can be controlled through regularization strength. The study reveals a critical intervention window where penalties applied early prevent shortcut formation, but the same penalties become less effective after the model has consolidated these shortcuts.

Researchers explored using large language models to detect and improve attention and sleep by analyzing EEG and physical activity data. While LLMs successfully generated personalized sleep improvement suggestions based on behavioral text data, the study found that directly detecting attention states and sleep stages from EEG data requires additional training data and domain expertise.
VeriEvol is a new framework for scaling multimodal mathematical reasoning in AI by treating data creation as a verifiable problem, combining evolved prompts with a multi-source verifier to ensure answer reliability. Testing shows the approach increases visual math accuracy from 35.42% to 54.73% when scaling from 10K to 250K samples, with reinforcement learning adding further gains of 3.88% points.
