 # Small-E-Czech
 
-Small-E-Czech is an [Electra](https://arxiv.org/abs/2003.10555)-small model pretrained on a Czech web corpus created at Seznam.cz. Like other pretrained models, it should be finetuned on a downstream task of interest before use. At Seznam.cz, it has helped improve web search ranking, query typo correction or clickbait titles detection. We release it under MIT license (i.e. allowing commercial use).
