World models that ignore human beliefs predict the wrong actions, new research shows
Current world models like Sora or Genie only simulate physics and ignore what people think, want, or feel. The new "Mental World Modeling" framework adds mental variables like beliefs and intentions. Even weaker language models using this approach outperform stronger models without mental modeling. The biggest bottleneck: predicting how physical and mental states change together. The article World models that ignore human beliefs predict the wrong actions, new research shows appeared first on The Decoder.
Study explains why AI agents benefit from "skills" and when they fail
A study from researchers at Princeton University and UC San Diego finds that so-called skills make AI agents better mainly through structured workflows, not through added knowledge. But as the skill library grows, agents have a harder and harder time finding the right set of instructions.

Multi-Document RAG: A Folder of Unrelated PDFs Is One Long Document with a Nested Outline
Enterprise Document Intelligence [Vol.1 #14B] - No shared fields means no index to build. One summary line per file plus each file’s own table of contents, and retrieval routes down two levels The post Multi-Document RAG: A Folder of Unrelated PDFs Is One Long Document with a Nested Outline appeared first on Towards Data Science.
Psychological methods reveal major weaknesses in AI security testing
Researchers at the UK AI Security Institute used psychometric methods to show that popular safety benchmarks for language models don't measure one consistent trait. Blanket blocking of requests can artificially inflate a safety score even as the model gets less useful day to day. The study also offers a method for catching models that act more cautious during tests than they do in normal use.

Netflix tests language model as alternative to hand-built recommendation logic
Netflix pitted its years-old recommendation engine against an in-house language model called GenRec and says it got better results. Instead of relying on thousands of hand-crafted features, GenRec converts viewing behavior into plain text. Netflix itself calls it "an early but promising step."

RayNeo's new AI glasses skip the camera, focus on text overlays
RayNeo launches an AI glasses with no camera and no speaker. The RayNeo iO Glasses overlay text into the wearer's field of view through a green waveguide display, with 97 percent transparency and about 1,300 nits of brightness. There's no camera and no built-in speaker. The glasses listen in on conversations, summarize them, extract action items, and suggest calendar entries that users can confirm with a head nod. A teleprompter mode and speech-to-text translation for 40 languages round out the feature set.
