·2026.11.11 10:44

Key point

The new backend executes torch.export .pte files directly in Chrome, Safari, and other WebGPU-enabled browsers without format conversion.

Details

  • New ExecuTorch backend allows PyTorch models to run on the GPU inside any WebGPU-enabled browser.
  • Eliminates the need to convert models to GGUF, ONNX, or TFLite formats.
  • Developers export models via torch.export to a single .pte file.
  • Supports execution in Chrome, Safari, and other WebGPU browsers, as well as natively on Metal, Vulkan, and D3D12.
