 ## Model description
 
-TinyBERT is 7.5 times smaller and 9.4 times faster on inference compared to its teacher BERT model (and DistilBERT is 40% smaller and 1.6 times faster than BERT). The model has been trained on 89_754 examples split into train, validation and test. Each label was perfectly balanced in each split.
