# TeenyTinyLlama-162m-FAQUAD

TeenyTinyLlama is a series of small foundational models trained on Portuguese.

This repository contains a version of [TeenyTinyLlama-162m](https://huggingface.co/nicholasKluge/TeenyTinyLlama-162m) fine-tuned on the [FAQUAD dataset]().

## Reproducing

```python
# Faquad-nli
