You can get started by installing Transformers.js v3 from NPM using:
npm i @huggingface/transformers
Then, importing the library with
import { pipeline } from "@huggingface/transformers";
or, via a CDN
import { pipeline } from "https://cdn.jsdelivr.net/npm/@huggingface/[email protected]";
For more information, check out the documentation.
⚡ WebGPU support (up to 100x faster than WASM!)
WebGPU is a new web standard for accelerated graphics and compute. The API enables web developers to use the underlying system's GPU to carry out high-performance computations directly in the browser. WebGPU is the successor to WebGL and provides significantly better performance, because it allows for more direct interaction with modern GPUs. Lastly, it supports general-purpose GPU computations, which makes it just perfect for machine learning!
Warning
As of October 2024, global WebGPU support is around 70% (according to caniuse.com), meaning some users may not be able to use the API.
If the following demos do not work in your browser, you may need to enable it using a feature flag:
Usage in Transformers.js v3
Thanks to our collaboration with ONNX Runtime Web, enabling WebGPU acceleration is as simple as setting device: 'webgpu'
when loading a model. Let's see some examples!
Example: Compute text embeddings on WebGPU (demo)
import { pipeline } from "@huggingface/transformers";
// Create a feature-extraction pipeline
const extractor = await pipeline(
"feature-extraction",
"mixedbread-ai/mxbai-embed-xsmall-v1",
{ device: "webgpu" },
});
// Compute embeddings
const texts = ["Hello world!", "This is an example sentence."];
const embeddings = await extractor(texts, { pooling: "mean", normalize: true });
console.log(embeddings.tolist());
// [
// [-0.016986183822155, 0.03228696808218956, -0.0013630966423079371, ... ],
// [0.09050482511520386, 0.07207386940717697, 0.05762749910354614, ... ],
// ]
Example: Perform automatic speech recognition with OpenAI whisper on WebGPU (demo)
import { pipeline } from "@huggingface/transformers";
// Create automatic speech recognition pipeline
const transcriber = await pipeline(
"automatic-speech-recognition",
"onnx-community/whisper-tiny.en",
{ device: "webgpu" },
);
// Transcribe audio from a URL
const url = "https://huggingface.co/datasets/Xenova/transformers.js-docs/resolve/main/jfk.wav";
const output = await transcriber(url);
console.log(output);
// { text: ' And so my fellow Americans ask not what your country can do for you, ask what you can do for your country.' }
Example: Perform image classification with MobileNetV4 on WebGPU (demo)
import { pipeline } from "@huggingface/transformers";
// Create image classification pipeline
const classifier = await pipeline(
"image-classification",
"onnx-community/mobilenetv4_conv_small.e2400_r224_in1k",
{ device: "webgpu" },
);
// Classify an image from a URL
const url = "https://huggingface.co/datasets/Xenova/transformers.js-docs/resolve/main/tiger.jpg";
const output = await classifier(url);
console.log(output);
// [
// { label: 'tiger, Panthera tigris', score: 0.6149784922599792 },
// { label: 'tiger cat', score: 0.30281734466552734 },
// { label: 'tabby, tabby cat', score: 0.0019135422771796584 },
// { label: 'lynx, catamount', score: 0.0012161266058683395 },
// { label: 'Egyptian cat', score: 0.0011465961579233408 }
// ]
🔢 New quantization formats (dtypes)
Before Transformers.js v3, we used the quantized
option to specify whether to use a quantized (q8) or full-precision (fp32) variant of the model by setting quantized
to true
or false
, respectively. Now, we've added the ability to select from a much larger list with the dtype
parameter.
The list of available quantizations depends on the model, but some common ones are: full-precision ("fp32"
), half-precision ("fp16"
), 8-bit ("q8"
, "int8"
, "uint8"
), and 4-bit ("q4"
, "bnb4"
, "q4f16"
).
Basic usage
Example: Run Qwen2.5-0.5B-Instruct in 4-bit quantization (demo)
import { pipeline } from "@huggingface/transformers";
// Create a text generation pipeline
const generator = await pipeline(
"text-generation",
"onnx-community/Qwen2.5-0.5B-Instruct",
{ dtype: "q4", device: "webgpu" },
);
// Define the list of messages
const messages = [
{ role: "system", content: "You are a helpful assistant." },
{ role: "user", content: "Tell me a funny joke." },
];
// Generate a response
const output = await generator(messages, { max_new_tokens: 128 });
console.log(output[0].generated_text.at(-1).content);
Per-module dtypes
Some encoder-decoder models, like Whisper or Florence-2, are extremely sensitive to quantization settings: especially of the encoder. For this reason, we added the ability to select per-module dtypes, which can be done by providing a mapping from module name to dtype.
Example: Run Florence-2 on WebGPU (demo)
import { Florence2ForConditionalGeneration } from "@huggingface/transformers";
const model = await Florence2ForConditionalGeneration.from_pretrained(
"onnx-community/Florence-2-base-ft",
{
dtype: {
embed_tokens: "fp16",
vision_encoder: "fp16",
encoder_model: "q4",
decoder_model_merged: "q4",
},
device: "webgpu",
},
);
See full code example
import {
Florence2ForConditionalGeneration,
AutoProcessor,
AutoTokenizer,
RawImage,
} from "@huggingface/transformers";
// Load model, processor, and tokenizer
const model_id = "onnx-community/Florence-2-base-ft";
const model = await Florence2ForConditionalGeneration.from_pretrained(
model_id,
{
dtype: {
embed_tokens: "fp16",
vision_encoder: "fp16",
encoder_model: "q4",
decoder_model_merged: "q4",
},
device: "webgpu",
},
);
const processor = await AutoProcessor.from_pretrained(model_id);
const tokenizer = await AutoTokenizer.from_pretrained(model_id);
// Load image and prepare vision inputs
const url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/tasks/car.jpg";
const image = await RawImage.fromURL(url);
const vision_inputs = await processor(image);
// Specify task and prepare text inputs
const task = "<MORE_DETAILED_CAPTION>";
const prompts = processor.construct_prompts(task);
const text_inputs = tokenizer(prompts);
// Generate text
const generated_ids = await model.generate({
...text_inputs,
...vision_inputs,
max_new_tokens: 100,
});
// Decode generated text
const generated_text = tokenizer.batch_decode(generated_ids, {
skip_special_tokens: false,
})[0];
// Post-process the generated text
const result = processor.post_process_generation(
generated_text,
task,
image.size,
);
console.log(result);
// { '<MORE_DETAILED_CAPTION>': 'A green car is parked in front of a tan building. The building has a brown door and two brown windows. The car is a two door and the door is closed. The green car has black tires.' }

💬 Improved text-generation
pipeline for conversational models
This version adds support for passing an array of chat messages (with "role" and "content" properties) to the text-generation
pipeline (PR). Check out the list of supported models here.
Example: Chat with Xenova/Qwen1.5-0.5B-Chat
.
import { pipeline } from '@xenova/transformers';
// Create text-generation pipeline
const generator = await pipeline('text-generation', 'Xenova/Qwen1.5-0.5B-Chat');
// Define the list of messages
const messages = [
{ role: 'system', content: 'You are a helpful assistant.' },
{ role: 'user', content: 'Tell me a funny joke.' }
]
// Generate text
const output = await generator(messages, {
max_new_tokens: 128,
do_sample: false,
})
console.log(output[0].generated_text);
// [
// { role: 'system', content: 'You are a helpful assistant.' },
// { role: 'user', content: 'Tell me a funny joke.' },
// { role: 'assistant', content: "Sure, here's one:\n\nWhy was the math book sad?\n\nBecause it had too many problems.\n\nI hope you found that joke amusing! Do you have any other questions or topics you'd like to discuss?" },
// ]
We also added the return_full_text
parameter, which means if you set return_full_text=false
, only the newly-generated tokens will be returned (only applicable if passing the raw text prompt to the pipeline).
🔢 Binary embedding quantization support
Transformers.js v2.17 adds two new parameters to the feature-extraction
pipeline ("quantize" and "precision"), enabling you to generate binary embeddings. These can be used with certain embedding models to shrink the size of the document embeddings for retrieval. This results in reductions in index size/memory usage (for storage) and improvements in retrieval speed. Surprisingly, you can still achieve up to ~95% of the original performance, but at 32x storage savings and up to 32x retrieval speeds! 🤯 Thanks to @jonathanpv for this addition in #691!
import { pipeline } from '@xenova/transformers';
// Create feature-extraction pipeline
const extractor = await pipeline('feature-extraction', 'Xenova/all-MiniLM-L6-v2');
// Compute binary embeddings
const output = await extractor('This is a simple test.', { pooling: 'mean', quantize: true, precision: 'binary' });
// Tensor {
// type: 'int8',
// data: Int8Array [49, 108, 24, ...],
// dims: [1, 48]
// }
As you can see, this produces a 32x smaller output tensor (a 4x reduction in data type with Float32Array → Int8Array, as well as an 8x reduction in dimensionality from 384 → 48). For more information, check out this PR in sentence-transformers, which inspired this update!

📝 Improved chat templating operation coverage
With this release, we're pleased to announce that Transformers.js is now able to parse every single valid chat template that is currently on the Hugging Face Hub! 🤯 As of 2024/03/05, this is around ~12k conversational models (of which there were ~250 unique templates). Of course, future models may introduce more complex chat templates, and we'll continue to add support for them!
For example, transformers.js can now generate the prompt for highly complex function-calling models (e.g., fireworks-ai/firefunction-v1):
See code
import { AutoTokenizer } from '@xenova/transformers';
const tokenizer = await AutoTokenizer.from_pretrained('fireworks-ai/firefunction-v1')
const function_spec = [
{
name: 'get_stock_price',
description: 'Get the current stock price',
parameters: {
type: 'object',
properties: {
symbol: {
type: 'string',
description: 'The stock symbol, e.g. AAPL, GOOG'
}
},
required: ['symbol']
}
},
{
name: 'check_word_anagram',
description: 'Check if two words are anagrams of each other',
parameters: {
type: 'object',
properties: {
word1: {
type: 'string',
description: 'The first word'
},
word2: {
type: 'string',
description: 'The second word'
}
},
required: ['word1', 'word2']
}
}
]
const messages = [
{ role: 'functions', content: JSON.stringify(function_spec, null, 4) },
{ role: 'system', content: 'You are a helpful assistant with access to functions. Use them if required.' },
{ role: 'user', content: 'Hi, can you tell me the current stock price of AAPL?' }
]
const inputs = tokenizer.apply_chat_template(messages, { tokenize: false });
console.log(inputs);

🤖 Qwen1.5 Chat models (0.5B and 1.8B)
Yesterday, the Qwen team (Alibaba Group) released the Qwen1.5 series of chat models. As part of the release, they published several sub-2B-parameter models, including Qwen/Qwen1.5-0.5B-Chat and Qwen/Qwen1.5-1.8B-Chat, which both demonstrate strong performance despite their small sizes. The best part? They can run in the browser with Transformers.js (PR)! 🚀 See here for the full list of supported models.
Example: Text generation with Xenova/Qwen1.5-0.5B-Chat
.
import { pipeline } from '@xenova/transformers';
// Create text-generation pipeline
const generator = await pipeline('text-generation', 'Xenova/Qwen1.5-0.5B-Chat');
// Define the prompt and list of messages
const prompt = "Give me a short introduction to large language model."
const messages = [
{ "role": "system", "content": "You are a helpful assistant." },
{ "role": "user", "content": prompt }
]
// Apply chat template
const text = generator.tokenizer.apply_chat_template(messages, {
tokenize: false,
add_generation_prompt: true,
});
// Generate text

console.log(output[0].generated_text);
// 'A large language model is a type of artificial intelligence system that can generate text based on the input provided by users, such as books, articles, or websites. It uses advanced algorithms and techniques to learn from vast amounts of data and improve its performance over time through machine learning and natural language processing (NLP). Large language models have become increasingly popular in recent years due to their ability to handle complex tasks such as generating human-like text quickly and accurately. They have also been used in various fields such as customer service chatbots, virtual assistants, and search engines for information retrieval purposes.'
🧍 MODNet for Portrait Image Matting
Next, we added support for MODNet, a small (but powerful) portrait image matting model (PR). Thanks to @cyio for the suggestion!
Example: Perform portrait image matting with Xenova/modnet
.
import { AutoModel, AutoProcessor, RawImage } from '@xenova/transformers';
// Load model and processor
const model = await AutoModel.from_pretrained('Xenova/modnet', { quantized: false });
const processor = await AutoProcessor.from_pretrained('Xenova/modnet');
// Load image from URL
const url = 'https://images.pexels.com/photos/5965592/pexels-photo-5965592.jpeg?auto=compress&cs=tinysrgb&w=1024';
const image = await RawImage.fromURL(url);
// Pre-process image
const { pixel_values } = await processor(image);
// Predict alpha matte
const { output } = await model({ input: pixel_values });
// Save output mask
const mask = await RawImage.fromTensor(output[0].mul(255).to('uint8')).resize(image.width, image.height);
mask.save('mask.png');
