EdgeAI, or edge artificial intelligence, refers to the deployment and execution of AI algorithms on edge devices—computing resources located near the data source such as smartphones, cameras, sensors, or local gateways—rather than in centralized cloud servers. By bringing computation closer to the data, edgeAI aims to reduce latency, lower bandwidth use, improve privacy, and enable operation in environments with intermittent connectivity. It often relies on specialized hardware accelerators and optimized software stacks to run neural networks and other AI models efficiently on devices with limited compute, memory, and power.

Key technologies include model optimization techniques such as quantization, pruning, and knowledge distillation; compact architectures such as TinyML models; and hardware accelerators found in edge devices (e.g., neural processing units, ASICs, GPUs). Software frameworks such as TensorFlow Lite, PyTorch Mobile, ONNX, and platform-specific runtimes support on-device inference, while ecosystems from vendors provide tools for hardware integration and deployment.

Applications span real-time analytics and control in autonomous vehicles, robotics, smart cameras and surveillance, industrial IoT, consumer wearables, and mobile apps. Benefits include lower latency for time-sensitive tasks, reduced need for continuous cloud connectivity, bandwidth savings, and improved privacy by keeping data local. Challenges involve limited compute and energy budgets, maintaining model accuracy after compression, secure update mechanisms, and governance over data and models across devices.

EdgeAI intersects with related concepts such as federated learning, on-device training, and fog computing, and it is supported by a growing landscape of hardware, software, and standards designed to optimize inference on resource-constrained devices.
