Right Answer, Wrong Evidence: A Deployment Gate for Grid-Diagnosis LLMs

TL;DR for operators A grid operator may see topology, live measurements, and an incident narrative all point to the same diagnosis. The decision is not only whether the answer is correct, but whether the model relied on evidence that the diagnostic task permits it to use. In the study, shortcut incident text produced a mean signed utility effect of +0.062 even though its preregistered engineering importance was zero. The model therefore became more accurate by using evidence that should not have determined the answer. Accuracy and a plausible explanation cannot reveal that divergence on their own. ...

None Taken: Why Video AI Must Learn When No Answer Is Correct

A camera sees the scene. The model reads the question. The options look reasonable. One of them must be right. That last sentence is the problem. Many enterprise video-AI workflows are built around this quiet assumption. A model reviews a warehouse clip and chooses the most likely safety violation. It watches a customer interaction and classifies the complaint. It checks a manufacturing video and identifies the defect category. The system may be wrong, of course, but the menu is treated as complete. The correct answer is assumed to be hiding somewhere among the choices, waiting for the model to point at it with sufficient confidence. ...

Rationales Before Results: Teaching Multimodal LLMs to Actually Reason About Time Series

Dashboard work has a familiar little ritual. Someone opens a chart, zooms into the last few points, notices a dip, a rebound, or a suspiciously clean trend line, and then says something that sounds analytical: “Looks like it will continue.” Sometimes that is wisdom. Sometimes it is just a human staring confidently at a squiggle. ...

Ghostwriters in the Machine: How Multi‑Agent LLMs Turn Raw Transport Data Into Decisions

A bus operator does not usually suffer from a shortage of charts. It suffers from the more irritating problem: charts that explain themselves only to the person who made them. The fuel-efficiency analyst has a histogram. The data scientist has a clustering plot. The operations manager has a timetable to defend, a fuel bill to reduce, and perhaps a driver-training programme to justify. Somewhere between those roles, insight quietly evaporates into a PDF appendix. ...
