Mainframe, MVS and zOS Discussion

IBM z/OS 3.1 is designed to help organizations meet their critical business needs with support provided by the following features and capabilities.

In z/OS 3.1, AI and analytics solutions such as the following are infused into the operating system, using intelligent automation and accelerated inferencing at scale to extract and leverage valuable data insights:

AI Framework for IBM z/OS provides foundational AI capabilities that are designed to support the incorporation and operationalization of prebuilt AI models, intended to augment z/OS and its components with intelligence that optimizes IT processes, designed to help simplify management, improves performance, and reduces skills requirements.
AI-powered Workload Manager (WLM), designed to intelligently predict upcoming batch workload and react accordingly to optimize system resources in a proactive way. This AI capability represents the first use case that leverages the AI Framework for IBM z/OS.
The Workload Manager is enhanced with performance measurement data analysis that is provided by the z/OSMF WLM Policy Advisor, designed to extract insights and identify suboptimal settings. Based on the analysis results, the user might need to adjust settings and policy definitions for optimized performance.
IBM SMF Explorer provides a data access and analysis toolkit that is designed to help even novice users access SMF data and extract insights in an easy and modern way, leveraging Python and Jupyter Notebooks
Furthermore, z/OS 3.1 extends the AI ecosystem by supporting a leading AI portfolio with the ability to deploy AI co-located with z/OS applications and data, designed for low latency response times.

This is a great news.

But the way we maintain most of our work, will AI be of any use in mainframes?

My understanding is that the mainframe AI enhancements are likely of most use to the banking and finance sector where things like automatic credit decisions or suspicious activity detection have been performed using AI techniques for quite some time. The inclusion of AI functionality in the z16 systems was to allow AI workloads to be offloaded into the hardware in order to provide better performance. Z/OS version 3 simply adds functionality to more easily exploit and use the hardware features to good effect. That said, for most of us it probably won't be noticed.
