Ever wondered how words “talk” to each other inside AI? This study borrows a brain-scanning idea—diffusion tensor imaging (DTI)—to trace how information moves through word embeddings in large language models. Most visualizations plot single words as points, ignoring the context that gives language meaning. This new tool follows

What if your AI could sense when a chat feels hard—or when you silently agree? This pilot study tests whether EEG signals can reveal mental workload and implicit agreement during spoken conversation with a conversational AI. Researchers reused established EEG classifiers in two voice-based tasks: a Spelling Bee and

What if you could guide a robot by drawing arrows that show pushes and pulls? Goal Force is a new way to steer video world models with physics, not vague text prompts. Instead of describing goals in words or target images, users sketch force vectors and intermediate dynamics. The model

TowerMind is a new, lightweight tower-defense game environment for testing AI agents, especially large language models (LLMs), on planning and decision-making. * Low compute cost and easy to run * Multimodal observations: pixels, text, and structured game state * Customizable levels and rules * Built-in tests for model hallucination The authors create five benchmark

TL;DR Large language models can sound confident, but if you nudge the context, their beliefs can fall apart. This paper proposes a better way to check if an AI keeps its story straight. * Problem: Popular checks like self-consistency can hide brittle knowledge. Answers that look reliable vanish under mild

AI agents usually follow a slow cycle: generate an idea, execute it, then check the results. This study shows a faster path: teach agents to predict outcomes first, then verify only the most promising options. * They build “execution priors” (inspired by world models) so runtime checks can be replaced by

What’s new VideoAR is a new way to generate videos with AI that predicts the next frame, over and over, at multiple scales. By separating what happens within a frame (spatial) from what happens across frames (temporal), it aims to make video generation faster and more stable. * 3D multi-scale

Texting with AI can feel off—messages arrive in odd bursts with no real “thinking” pauses. Stephanie2 changes that. * Decides to send or wait: At every step, it chooses to message now or hold, like a human pausing to think. * Natural timing: It models delay as thinking time + typing time,

New research shows that popular language models don’t persuade everyone the same way. Across 13 LLMs and 16 languages, the authors found consistent shifts in tone, appeals, and strategies depending on the recipient’s labeled gender — patterns that mirror well-known gender stereotypes. * Framework tests 19 categories of persuasive language

Can AI help us disagree better? Democracy thrives when diverse voices are heard, but at scale, participation, political equality, and meaningful discussion often pull against each other. New research asks whether AI mediators powered by large language models can ease this trilemma. Building on a recent tool that helped people
AI
AI agents powered by large language models can call tools, but they also hallucinate: picking the wrong tool, sending malformed parameters, or bypassing tools by simulating results. That breaks reliability, security, and audit trails in production. This study shows a lightweight way to catch those mistakes in real time. Instead

How do we know if game-playing AIs can plan, act, and remember like good teammates? Meet MineNPC-Task—a new open benchmark for memory-aware AI agents inside Minecraft’s open world. Instead of toy prompts, tasks come from real co-play sessions with expert players, then get turned into templates with clear
