ai.onnx.CastLike

ai.onnx · standard ONNX operator · ONNX opset ≥ 25

Description

Casts every element of input to the same dtype as target_type, producing an output with the same shape as input. The target_type tensor itself is used only for its dtype and is not read elementwise.

See the ONNX CastLike spec for the reference semantics.

• metadata.json — kernel metadata (id, digests, provenance)
• manifest.json — the op contract (source of truth)

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.CastLike", { version: 1 });
const { y } = await kernel({ x: { data: xData, shape: [] }, target: { data: targetData, shape: [3] } });
