models

Definitions of all models available in Transformers.js.

Example: Load and run an `AutoModel`.

    import { AutoModel, AutoTokenizer } from '@xenova/transformers';

    let tokenizer = await AutoTokenizer.from_pretrained('Xenova/bert-base-uncased');
    let model = await AutoModel.from_pretrained('Xenova/bert-base-uncased');

    let inputs = await tokenizer('I love transformers!');
    let { logits } = await model(inputs);
    // Tensor {
    //     data: Float32Array(183132) [-7.117443084716797, -7.107812881469727, -7.092104911804199, ...]
    //     dims: (3) [1, 6, 30522],
    //     type: "float32",
    //     size: 183132,
    // }

We also provide other `AutoModel`s (listed below), which you can use in the same way as the Python library. For example:

Example: Load and run a `AutoModelForSeq2SeqLM`.

    import { AutoModelForSeq2SeqLM, AutoTokenizer } from '@xenova/transformers';

    let tokenizer = await AutoTokenizer.from_pretrained('Xenova/t5-small');
    let model = await AutoModelForSeq2SeqLM.from_pretrained('Xenova/t5-small');

    let { input_ids } = await tokenizer('translate English to German: I love transformers!');
    let outputs = await model.generate(input_ids);
    let decoded = tokenizer.decode(outputs[0], { skip_special_tokens: true });
    // 'Ich liebe Transformatoren!'
