SMILES were used as input, and IUPAC names were tokenised by character. This contained 132 unique SMILES tokens with a maximum length of 600 characters, while the IUPAC name contained 68 unique tokens with a maximum length of 600 characters. Compared with the 50 million datasets, the maximum length of input and output tokens has increased by 200 characters, while the size of input and output tokens has remained relatively unchanged.
