Text2Struc LLM also manages to suggest sites when they are not given in the prompt, see Figure . Both "Robocrystal" and "Spacegroup" prompts contain only the formula and space group name, requiring the model to suggest lattice parameters and sites. "API, code" generates structures that match the original structure with similar frequencies: 8% for "Robocrystal" and 9% for "Spacegroup".
