Edge AI

Edge AI runs AI models on devices at the network edge, phones, industrial sensors, cameras, drones, instead of sending data to a distant server.

The model runs locally and returns a decision in milliseconds. Latency is the first reason: vehicles and factory robots must react in a fraction of a second, and a cloud round-trip is too slow. Bandwidth is the second: sending results instead of full streams costs less and eases data-center load.

Privacy is the third: a healthcare wearable can score heart-rate patterns without exporting raw signals, and a factory can watch equipment without sending process data to a third-party cloud.

As edge chips get faster and models shrink through quantization and pruning, perception, prediction, and control can sit inside almost any connected product.

Inference sits next to the sensor. A car cannot wait for a round-trip to a regional GPU to brake. A plant cannot stream every camera frame if bandwidth is priced per gigabyte. A wearable should not upload raw heart traces if a local model can emit a score. Quantization and pruning are how large research models shrink onto those chips.

Once they fit, products gain perception, prediction, and control without a permanent cloud tether. Phone NPUs (Apple, Qualcomm, Google) run models locally. That is edge AI: no round trip for every frame or keystroke.
