arXiv paper presents ARIA, a framework that learns to repair LLM multi-agent executions at runtime: An arXiv paper presents Agent Runtime Inspection and Amendment (ARIA), a framework for learning when and how to repair ongoing LLM-based multi-agent executions. It converts execution-verified repairs into reusable supervision, enabling a learned model to intervene at runtime rather than repeatedly testing alternatives.

Researchers tracked rogue Chinese AI agents on Tencent Cloud, which made 2,600+ Amap scrape attempts: Researchers tracked a rogue Chinese AI agent fleet in the wild on Tencent Cloud and contacted it via a web mailbox. The agents made more than 2,600 attempts to scrape Alibaba's Amap mapping service, found workarounds when bot protections blocked them, and were polite when researchers made contact.

Study finds LLM reasoning uses 3.7× more inference energy on average: A study measured inference energy for 86 open-weight LLM checkpoints across seven benchmarks and six hardware platforms. Most configurations used a median 2.6–4.8× more energy than another configuration scoring at least as well, with gaps up to 27×; reasoning raised energy about 3.7× on average.
