If the result holds in production, it could improve utilization and reduce the CPU bottlenecks that slow agents and keep reinforcement-learning GPUs waiting. [Modal](https://modal.com/?ref=runtimewire), whose founder and CEO is [Erik Bernhardsson (@bernhardsson)](https://x.com/bernhardsson?ref=runtimewire), is weighing whether [NVIDIA's Vera CPU](https://nvidianews.nvidia.com/news/nvidia-unveils-vera-the-cpu-for-agents?ref=runtimewire) can ease a problem AI workloads make unusually visible: the computer running an agent can hold up the rest of the system.… When you purchase through links in our articles, [we may earn a small commission](https://runtimewire.com/affiliate-monetization-standards).
