Excellent comparison of how on-device agentic AI is evolving across Android and iOS. I particularly liked the distinction between Android’s modular approach and Apple’s more integrated ecosystem, because the right architecture depends on much more than model capability. Privacy, permissions, tool validation, battery usage, observability, and recovery from failed actions all become critical once an AI can act rather than simply respond. A future article demonstrating the same agent workflow implemented on both platforms would be very valuable.
