We note that CIF printing could have a higher error rate because the baseline model was designed and originally trained to generate code. Previous results in the literature have shown good performance for generating crystal structures using larger models , but we note that we also focus on transformations, which complicate the task, see Figure . For example, the performance of substitution transformation is twice as low as that of other transformations. "Unmodified" -no transformation, (2) "Strain" transformation, (3) "Vacancy", (4) "Supercell", and ( ) "Substitution" by percentage.
