A 3B T5 model trained on the P3 (T0 split) dataset for 20,000 steps with a batch size of 2048 a maximum input sequence length of 1024, a maximum output sequence length of 256, and the Adafactor optimizer with a constant learning rate of 0.001. The model is trained from the T5 v1.1 lm-adapt checkpoint and fully finetuned.
