 ### Transfer-learning Pretraining
 
-The model was trained on a single TPU Pod V3-8 for 240,000 steps in total, using sequence length 512 (batch size 4096).
+The model was trained on a single TPU Pod V3-8 for 500,000 steps in total, using sequence length 512 (batch size 4096).
 It has a total of approximately 220M parameters and was trained using the encoder-decoder architecture.
 The optimizer used is AdaFactor with inverse square root learning rate schedule for pre-training.
