Summary
A paper on arXiv argues that AI chips sit mostly idle while serving models, because replies must be fast and each step waits on memory. The authors report that on two large open models, the math units were busy only about 6-11% of the time. They propose that the GPU needs an operating system that keeps urgent work on schedule and fills idle capacity with other useful work. According to the snippet, a feature that ships today recovers a quarter of a GPU with work designed to share, and a tenth with real work.

What happened
AI chips sit mostly idle while serving models, because replies must be fast and each step waits on memory. On two large open models, the math units were busy only about 6-11% of the time. We argue the GPU needs an operating system that keeps urgent work on schedule and fills idle capacity with other useful work. A...
Why it matters
Builders and businesses running AI models on GPUs could see wasted capacity as a cost and throughput issue, since the snippet says most compute goes unused during serving. If scheduling ideas like this work in practice, operators may be able to run more useful work on the same hardware. The snippet is a preprint abstract, so readers should watch for independent results and whether the approach reaches production systems.
