-To stimulate the future of open development of neural text generation in Portuguese, we present both **[GigaVerbo](https://huggingface.co/datasets/TucanoBR/GigaVerbo)**, a concatenation of deduplicated Portuguese text corpora amounting to 200 billion tokens, and **[Tucano](https://huggingface.co/TucanoBR/Tucano-2b4)**, a series of decoder-transformers natively pre-trained in Portuguese. All byproducts of our study, including the source code used for training and evaluation, are openly released on [GitHub](https://github.com/Nkluge-correa/Tucano) and Hugging Face.
