OrtProvider enum

Execution providers for ONNX Runtime.

Implementation Status

✅ Fully Implemented (with dedicated configuration):

  • cpu — Always available
  • coreML — iOS/macOS with dedicated options
  • nnapi — Android with flags (FP16, NCHW, CPU disabled)
  • xnnpack — Android with thread configuration

⚠️ Generic API Only (may work but no dedicated support):

  • webGpu — WebGPU via Dawn (Android GPU)
  • qnn — Qualcomm Neural Network (placeholder)
  • cuda — NVIDIA CUDA (placeholder)
  • tensorRT — NVIDIA TensorRT (placeholder)
  • rocm — AMD ROCm (placeholder)
  • openVINO — Intel OpenVINO (placeholder)
  • dnnl — Intel oneDNN (placeholder)
