## TL;DR

WebGPU is a web platform API for GPU-backed rendering and general-purpose computation. The public article is now limited to the standard API shape, the WGSL shader language, and the browser-facing request flow documented by W3C and MDN.

## Core Explanation

The safe public summary is that WebGPU gives web applications structured access to GPU devices through adapters, devices, queues, command encoders, and shader modules. WGSL is the shading language specified for WebGPU programs, and browser code begins by requesting an adapter and then a device before submitting GPU work.
