deps: bump @huggingface/transformers from 4.2.0 to 4.3.0

[dependabot]

Bumps @huggingface/transformers from 4.2.0 to 4.3.0.

Release notes

Sourced from @​huggingface/transformers's releases.

4.3.0

🚀 Transformers.js v4.3 — Structured Output, New Models, WebGPU upgrade, Documentation Overhaul

This release adds structured output, three new model architectures, WebGPU support for Safari 26+, and a documentation overhaul. We also upgraded ONNX Runtime to the latest version.

What's new?

Structured output

Constrain generation to a JSON schema, JSON object, or regular expression with the experimental, dependency-free @huggingface/transformers-structured-output package in huggingface/transformers.js#1758.

For example, classify customer feedback into a fixed set of sentiments and topics:

import { pipeline, TextStreamer } from "@huggingface/transformers";
import { StructuredOutputProcessor } from "@huggingface/transformers-structured-output";
// Create the pipeline first so its tokenizer is available.
const generator = await pipeline(
"text-generation",
"onnx-community/LFM2.5-350M-ONNX",
{ dtype: "q4f16", device: "webgpu" },
);
const processor = new StructuredOutputProcessor(generator.tokenizer, {
type: "json_schema",
json_schema: {
type: "object",
properties: {
sentiment: { enum: ["positive", "negative", "neutral"] },
topic: { enum: ["price", "quality", "delivery", "other"] },
},
required: ["sentiment", "topic"],
additionalProperties: false,
},
});
const messages = [
{
role: "user",
content: "Classify this feedback: The product is way too expensive.",
},
];
const output = await generator(messages, {
max_new_tokens: 512,
do_sample: false,
streamer: new TextStreamer(generator.tokenizer, {
skip_prompt: true,
skip_special_tokens: true,
</tr></table>
