plT5 Base

plT5 models are T5-based language models trained on Polish corpora. The models were optimized for the original T5 denoising target.

Corpus

plT5 was trained on six different corpora available for Polish language:

Tokenizer

The training dataset was tokenized into subwords using a sentencepiece unigram model with vocabulary size of 50k tokens.

Usage

Example code:

from transformers import AutoTokenizer, AutoModel

tokenizer = AutoTokenizer.from_pretrained("allegro/plt5-base")
model = AutoModel.from_pretrained("allegro/plt5-base")
