LLMs are getting better at reasoning—but can they act in the world? VirtualEnv is a new open-source simulation platform (built on Unreal Engine 5) that lets researchers put AI agents to the test in rich, interactive 3D worlds.

Fine-grained benchmarking of embodied skills: navigation, object manipulation, multi-agent teamwork.
Game-inspired tasks: escape rooms and procedurally generated levels.
Natural-language API to deploy and control agents.
Integrates LLMs and vision-language models to generate environments and structured tasks from text, images, and video.
Tools for procedural task generation, validation, and real-time environment control.
Comparative benchmarks reveal differences in planning, adaptability, and coordination across popular models.

Built for embodied AI, gaming, and robotics research—and released open-source. Learn more and try it: https://arxiv.org/abs/2601.07553v1

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

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

Meet GenomAgent: A Team of AI Specialists for Smarter Genomics Q&A

TL;DR: Finding reliable answers in genomics is hard. GenomAgent turns one big AI into a coordinating team of specialists—and beats the current leader by 12% on a key benchmark. Genomic facts live across many databases. Standard chatbots struggle because they can’t flexibly query those sources. GeneGPT added
