# DeBERTinha XSmall (aka "debertinha-ptbr-xsmall")

## Introduction

DeBERTinha is a pretrained DeBERTa model for Brazilian Portuguese.

## Available models

| Model                                    | Arch.      | #Params |
| ---------------------------------------- | ---------- | ------- |
| `sagui-nlp/debertinha-ptbr-xsmall`       | DeBERTa-V3-Xsmall | 40M    |

## Usage

```python
from transformers import AutoTokenizer
from transformers import AutoModelForPreTraining
from transformers import AutoModel

model = AutoModelForPreTraining.from_pretrained('sagui-nlp/debertinha-ptbr-xsmall')
tokenizer = AutoTokenizer.from_pretrained('sagui-nlp/debertinha-ptbr-xsmall')
```

### For embeddings

```python
import torch

model = AutoModel.from_pretrained('sagui-nlp/debertinha-ptbr-xsmall')
input_ids = tokenizer.encode('Tinha uma pedra no meio do caminho.', return_tensors='pt')

with torch.no_grad():
    outs = model(input_ids)
    encoded = outs.last_hidden_state[0, 0]  # Take [CLS] special token representation
```
