+          GPUs have become essential for drawing complex images efficiently, including for rendering virtual reality and augmented reality scenes in real-time as needed by the <a href="https://www.w3.org/TR/webxr/">WebXR Device API</a>. GPUs are also at the heart of computations that leverage parallelism, such as machine learning inference.

+          Web applications may leverage GPUs through the <a href="https://www.khronos.org/webgl/">WebGL</a> family of APIs, but WebGL does not enable access to more advanced features of GPUs, focuses on drawing images and does not provide first-class support for performing general computations, and is not agnostic of the GPU system API exposed by the underlying operating system.
         </p>
+        <p>
+          The overall goal of the GPU for the Web Working Group is to provide a foundation that can be implemented on top of modern GPU system APIs to expose modern GPU functionality on the Web, both for computation and for image rendering.
