This version of the model is trained on OpenHearthstone v0.1 dataset under the scheme of SAS (state, action as input and next state as output) which is considered to be a annotation-free scheme.

This model used the pretrained version from long-t5-tglobal-base and finetuned for 10 epochs to overfit on the dataset.

The data serializer for this version encoded game tags into readable words and attached the value for the tag subsequently. The separation character used between entities is |.

An example input action + input state, predicted next state and groundtruth next state is demonstrated below:
