 Run ExecuTorch models on the GPU via [WebGPU](https://www.w3.org/TR/webgpu/). The backend compiles delegated subgraphs into WGSL compute shaders executed natively through [wgpu-native](https://github.com/gfx-rs/wgpu-native) (Metal on macOS, Vulkan on Linux/Windows).
 
-> **Status: Prototype.** The backend supports a single operator today and is under active development. See [TODO.md](TODO.md) for the roadmap.
+> **Status: Prototype.** The backend supports `add` and `rms_norm` today and is under active development. See [Progress](#progress) for shipped milestones.

+
+| Date | Milestone | Pull Request |
+|---|---|---|
+| 2026-04 | Made it possible to run ExecuTorch models on the GPU through WebGPU — built the backend from the ground up, including the runtime delegate that builds the GPU graph (buffers, pipelines, bind groups) and runs the model on Metal and Vulkan | [#18808](https://github.com/pytorch/executorch/pull/18808) |
+| 2026-06 | Grew model support beyond element-wise operators — added the root-mean-square normalization operator (`rms_norm`) and named-data weight loading | [#19963](https://github.com/pytorch/executorch/pull/19963) |
+| 2026-06 | Made sure every change is automatically tested — added WebGPU to ExecuTorch's standard backend test suite, running on Linux/x86 in CI | [#19964](https://github.com/pytorch/executorch/pull/19964) |
+| 2026-06 | Removed a class of bugs and manual upkeep — the WGSL shaders are now generated automatically, with a build-time check that fails the build on shader/source drift | [#19981](https://github.com/pytorch/executorch/pull/19981) |
+| 2026-06 | Got the test suite to actually run work on the GPU — added operator-allowlist delegation (unsupported operations fall back to the CPU) and a process-wide GPU device context, so models execute on the GPU during testing | [#20036](https://github.com/pytorch/executorch/pull/20036) |
+
+In review:
+
+| Milestone | Pull Request |
+|---|---|
+| Makes testing match the WebGPU standard exactly — switches the tests to Google's Dawn shader compiler (Tint, the source-of-truth WGSL implementation) running on SwiftShader for headless GPU execution | [#20079](https://github.com/pytorch/executorch/pull/20079) |
+| Strengthens correctness for models that run in several GPU passes — adds dispatch-ordering and scratch-buffer (temporary GPU memory) tests | [#20080](https://github.com/pytorch/executorch/pull/20080) |
