Model Card

MODNet portrait matting (fp16)

Browser-ready import artifacts for portrait-matting, produced by SkillSafe's reproducible converter (`models/` in skillsafe.ai) from a pinned upstream source. Every byte here is derivable from that source plus the recipe below; nothing was edited by hand.

registry files are parameter files served from models.skillsafe.ai once vetted; bundle files ship inside an app; registry-shared is a runtime library reused by every model of the same architecture.

Verification

Imported as published upstream (no conversion). Each file is pinned by SHA-256 to its source; every ONNX file passed onnx.checker and a CPU smoke run under onnxruntime with zero-filled inputs at the declared shapes:

file	inputs	outputs	ms
`onnx/model_fp16.onnx`	input[1, 3, 512, 512]	output[1, 1, 512, 512]	53.6

Use in the browser

import * as ort from "onnxruntime-web";
const session = await ort.InferenceSession.create("https://huggingface.co/skillsafe-ai/modnet/resolve/main/onnx/model_fp16.onnx", { executionProviders: ["webgpu", "wasm"] });

Contract (onnx/model_fp16.onnx): input input float32 ['batch_size', 3, 'height', 'width'] → output output float32 ['batch_size', 1, 'height', 'width']. Opset 11.
