ai.onnx.Mul

ai.onnx · standard ONNX operator · ONNX opset ≥ 14

Description

Performs elementwise binary multiplication of two tensors with multidirectional (NumPy-style) broadcasting. The output has the same element type as the inputs.

See the ONNX Mul spec for the reference semantics.

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/ai.onnx.Mul", { version: 1 });
const { c } = await kernel({ a: { data: aData, shape: [] }, b: { data: bData, shape: [] } });
