I watched the video mentioned in the post [1], but now I’m more confused than before…

What are the benefits, if any, of using gpu.cpp instead of just webgpu.h (webgpu native) directly? Maybe each is tailored for different use cases?

The raw WebGPUAPI is geared towards infrastructure type of usage, eg ML compilers, game engines, etc and is pretty verbose for application and research use cases.

Under examples/, for pedagogical purposes + help contributors understand what happens with WebGPU under the hood, I actually included an example of invoking the same GELU kernel as in the hello world example without gpu.cpp. It looks like this and is ~ 400+ LoC and also will take several minutes to build Dawn:

A goal of gpu.cpp is to make the power of webgpu much less painful to integrate into a project without having to jump through as many hoops (+ also sets up the prebuilt shared library so builds are instantaneous and painless instead of reams of cmake hassles + 5-10 minutes of waiting for dawn to build):
