 Dutch T5 Models  Three types of [Dutch T5 models have been trained (blog)](https://huggingface.co/spaces/yhavinga/pre-training-dutch-t5-models). `t5-base-dutch` is the only model with an original T5 config. The other model types t5-v1.1 and t5-eff have `gated-relu` instead of `relu` as activation function, and trained with a drop-out of `0.0` unless training would diverge (`t5-v1.1-large-dutch-cased`). The T5-eff models are models that differ in their number of layers. The table will list the several dimensions of these models. Not all t5-eff models are efficient, the best example being the inefficient `t5-xl-4L-dutch-english-cased`.   |                   | [t5-base-dutch](https://huggingface.co/yhavinga/t5-base-dutch)   |
