com.microsoft · ONNX Runtime contrib operator · contrib since_version 1

Description

Applies GELU to A + B, where the 1-D bias B is broadcast along the last dimension of A. This implementation supports float16 and float32; the schema's double and bfloat16 types are not implemented.

See the ONNX Runtime BiasGelu contrib-operator spec for the reference semantics.

Files

• metadata.json — kernel metadata (id, digests, provenance)
• manifest.json — the op contract (source of truth)
• test.json — correctness cases
• bench.json — benchmark + tuning cases
• elementwise-bias-gelu.wgsl.jinja

Use with @huggingface/kernels

The loader derives every required output's shape and logical dtype from the manifest contract and this call. It then allocates the result tensors automatically.

The version: 1 option selects the published kernel contract; it is independent of any operator opset, contrib since_version, or model version.

Replace each *Data placeholder with a typed array containing the corresponding input data.

import { getKernel } from "@huggingface/kernels";

const kernel = await getKernel("webgpu-kernels/com.microsoft.BiasGelu", { version: 1 });
const { C } = await kernel({ A: { data: AData, shape: [3] }, B: { data: BData, shape: [3] } });
