of classes that's all you have to train in addition to pre to fine-tuning vert itself alright so they kind of evaluate on all of these tasks they get super duper numbers on all of them here burped large winds on pretty much everything and this model is big just saying and they trained it on TP use which is available in kind of Google cloud infrastructure so far they've trained it on a lot of data so - - away it's it's kind of expected that you would outperform but it's very surprising that you outperform everyone else by this much and they've
