Why On-Device AI Is Quietly Winning Over Cloud Inference — Three Reasons You Didn't See Coming

I noticed something odd a few months ago. Several engineers I respect - people building serious AI pipelines, not hobbyists - quietly shifted from API-based inference back toward running models locally. Not because of some principled stance. Not because they read a blog post. Because they hit real problems and local inference solved them faster than any API change could. Nobody announced this. There was no "local AI is back" wave on Twitter. It just. happened.
