The rise of latent consistency models (LCMs) has opened a new frontier for generative and restorative tasks such as image super‑resolution, video frame interpolation, and audio denoising. However, LCMs are computationally heavy: they rely on iterative diffusion‑like processes that traditionally require powerful GPUs. ...

Introduction The web is evolving from a static document delivery platform into a compute‑rich ecosystem where browsers can run sophisticated machine‑learning workloads locally. For autonomous web agents—software entities that navigate, interact, and make decisions on behalf of users—low‑latency inference is a non‑negotiable requirement. Cloud‑based APIs introduce network jitter, privacy concerns, and cost overhead. By moving inference to the edge (i.e., the client’s device) and leveraging the WebGPU API, developers can achieve near‑real‑time performance while keeping data local. ...
