PyTorch says its new ExecuTorch WebGPU backend runs PyTorch models locally on browser GPUs without converting them to another framework's format. Developers export a model to an ExecuTorch file that can run across WebGPU browsers, keeping inputs and outputs on the device.

The project reports support for language, vision, speech and on-device fine-tuning workloads. In tests of quantized Llama 3.2 1B and Qwen3-0.6B in Chrome on an Apple M1 Pro, it reports 4-7× faster prompt processing and 2-10× faster token generation than ExecuTorch's WebAssembly CPU backend. The backend remains in early development, with further work planned on stability and model coverage.
