Reading

The WASM build downloads smaller here: 302.5 MB (uint8) against 432.1 MB (q4f16) for WebGPU. The CPU-fallback quant compresses tighter than the GPU pick for this model.

The quant ladder spans 3.6x: 302.5 MB (uint8) to 1.07 GB (fp32).

Use it with Transformers.js

import { pipeline } from "@huggingface/transformers";

const pipe = await pipeline("token-classification", "onnx-community/piiranha-v1-detect-personal-information-ONNX", {
  device: "webgpu", // usually falls back to "wasm"; wrap in try/catch for production
  dtype: "q4f16", // use "uint8" for the WASM build
});

const result = await pipe(/* your input */);

Requires npm install @huggingface/transformers (or the CDN build).

FAQ

WebGPU or WASM for Piiranha v1 (PII Detection), in practice?

Chrome, Edge, and Safari 26+ run the WebGPU build (q4f16) on the GPU. Firefox has WebGPU on Windows and Apple Silicon Macs but not everywhere yet. Any browser without a WebGPU adapter falls back automatically to the WebAssembly build (uint8) on CPU: same model, slower to load, slower to run.

What does q4f16 mean for Piiranha v1 (PII Detection)?

The WebGPU build here uses q4f16: 4-bit weights with some layers kept at 16-bit for stability: WebGPU's usual smallest clean build. The WASM fallback uses uint8: 8-bit integers: about a quarter the size of fp32, with a smaller quality trade than 4-bit.
