arXiv Trending AI — 2026-09-16

This is the daily AI cast for September sixteenth, twenty twenty-six, covering eight papers from the latest arXiv announcement batch. The strongest signal is operational reliability. Instead of treating a model as a complete system, these papers add social harnesses, feedback loops, abstention controls, uncertainty estimates, memory, and faster inference.
