We believe this capability arises from its extensive presence in pretraining datasets. Natural language can also be use to describe crystal structures. For example, we might say mp-13 in Material Project as: The structure's cell parameters are (2.86 Å, 2.86 Å, 2.86 Å, 90 • , 90 • , 90 • ), the space group is 229 (Im-3m), and a Fe atom occupies its 2a Wyckoff position, (further details are omitted here for brevity).
