model that we've learned and we're just going to fine-tune it directly we're not going to like precache the features like kind of words of Exile we're just gonna you know take it whatever parameters that language model learned predicting the sequence we're going to use that as an initialization point for training a supervised model for a downstream task and this is the one that started to get good results and they were showing compared to standard supervised learning on you know datasets with like 20,000 labeled examples and stuff like that
