A user reports that despite disabling Siri through multiple settings and services on macOS 27, the Siri AI process continues running in Activity Monitor. They question whether it is possible to fully disable Siri and Apple Intelligence features, comparing them to Microsoft's Recall.
This paper introduces Effective State-Size (ESS), a metric measuring how well sequence models utilize their memory by analyzing the rank of input-dependent transformation matrices. ESS reveals that models with high memory utilization are harder to distill, and that effective ESS modulation correlates with better performance on recall-intensive tasks.
