MOTIVE: Teaching AI Video Models to Move Better

AI-generated videos often look great frame by frame—but the motion between frames can jitter, drift, or break physics. A new study introduces Motive, a motion-first way to find which training clips actually drive how a model moves.

Instead of focusing on static appearance, Motive uses gradient-based influence signals weighted by motion to pinpoint clips that help—or hurt—temporal dynamics in text-to-video systems.

Curates better fine-tuning data by selecting high-impact motion clips
Improves temporal consistency and physical plausibility
Scales to large, modern video datasets and models

With Motive-picked data, the team improved motion smoothness and dynamic degree, achieving a 74.1% human preference win rate on VBench versus the base model.

This is the first framework to attribute motion (not just looks) in video generators—paving the way for fewer jittery, more believable AI videos.

Meet GRACE: a moral governor for safer, more transparent AI

AI agents are getting powerful—so how do we make sure they do the right thing, not just the effective thing? Meet GRACE, a reason-based moral governor that keeps AI behavior aligned with human norms by separating moral reasoning from goal-driven decision-making. * Moral Module: uses deontic logic and explicit reasons

Why some fine-tuned LLMs miss phishing—and how to fix it

Not all fine-tuned LLMs spot phishing equally. A new study tests Llama 3.1 8B, Gemma 2 9B, and Mistral on high-stakes phishing detection—and uses SHAP and mechanistic interpretability to reveal why models do (or don’t) generalize. * Architecture × data diversity matters: Gemma 2 9B hits state-of-the-art performance (F1

AI that explains itself—by following the science Black-box AI can be powerful, but it often can’t tell us why it made a decision. Concept Bottleneck Models (CBMs) try to fix that by predicting human-understandable concepts first, then the final answer. The catch: standard CBMs ignore domain-specific cause-and-effect and
