 with multi-sentence inputs. As a result, our best model establishes new state-of-the-art results on the GLUE, RACE, and
 SQuAD benchmarks while having fewer parameters compared to BERT-large.*

+## Usage tips
 
 - ALBERT is a model with absolute position embeddings so it's usually advised to pad the inputs on the right rather
   than the left.
@@ -56,11 +59,7 @@ Tips:
 - Layers are split in groups that share parameters (to save memory).
 Next sentence prediction is replaced by a sentence ordering prediction: in the inputs, we have two sentences A and B (that are consecutive) and we either feed A followed by B or B followed by A. The model must predict if they have been swapped or not.
