Descripción

help wanted performance

This task tracks backend coverage across the models wired in the registry.

Regenerated from packages/react-native-executorch/src/models.ts on main plus the Vulkan variants wired in #1479, so it reflects what the library actually resolves rather than what exists on Hugging Face. 104 models across 15 task groups.

Columns

  • CPU (XNNPACK) runs on both platforms; it is the portable fallback and every model has it.
  • Android GPU (Vulkan) is Android only.
  • iOS (Core ML / MLX) is Apple only. Core ML reaches ANE/GPU/CPU; MLX targets Apple Silicon GPU.

Cells list the published precision variants, so 8da4w, fp16 means both are wired. — means the model has no variant for that column.

Notes

  • Vulkan on LFM2.5 is the VL variants only (LFM2_5_VL_450M, LFM2_5_VL_1_6B); the text-only 350M and 1.2B are XNNPACK plus MLX.
  • Published Vulkan exports of EfficientNet, selfie segmentation, LR-ASPP and SSDLite are not wired: each measured slower than the current Android default (#1479).
  • RF-DETR keypoint intentionally has no MLX variant: on an iPhone 16, Core ML fp16 measured 141.6 ms / 248 MB against MLX fp32 at 382.2 ms / 1153 MB, and the MLX delegate has no quantized convolution to close the gap.
  • Core ML text embedders accept a 1-token input as of the seq=1 export fix (react-native-executorch#1164).
