Mikhailo/mT5-small-ITN-uk

mT5-small ITN Ukrainian

Inverse Text Normalization model for Ukrainian, fine-tuned from google/mt5-small.

For fast CPU inference, use the CTranslate2 version: Mikhailo/mT5-small-ITN-uk-ct2

Usage

from transformers import MT5ForConditionalGeneration, AutoTokenizer
import torch

tok = AutoTokenizer.from_pretrained("Mikhailo/mT5-small-ITN-uk")
model = MT5ForConditionalGeneration.from_pretrained("Mikhailo/mT5-small-ITN-uk").eval()

def itn(text):
    inp = tok(text, return_tensors="pt")
    with torch.no_grad():
        out = model.generate(**inp, max_new_tokens=140, num_beams=4)
    return tok.decode(out[0], skip_special_tokens=True)

print(itn("сорок два відсотки населення"))   # → 42% населення
print(itn("пʼятнадцять доларів і двадцять центів"))  # → $15.20
