Operational requirements
The images are general-purpose images and have no special requirements for running.
Important features
Images with the `optimised` tag are BaseOS (Optimized) images. These images are built on BaseOS images and include the garbage collection (GC) optimization for Python 3. This optimization effectively reduces GC pause issues in AI scenarios.
