The chemical diversity metric in Figure indicates that coarse prompts generally lead to higher δ c than fine prompts. In particular, prompts F-H exhibit the highest levels of chemical diversity across all prompts, with G exhibiting the highest overall. This matches the trend in d z from Figure since more significant changes are made to the molecules, which can induce higher diversity. Among the fine prompts, A yields a slightly higher δ c than the others. The diversity metrics for similar prompts show that the generated molecules have a suitable range of structural variations and do not typically exhibit mode collapse. This indicates that the navigation paths through the chemical space, guided by the prompts, yield molecules with distinct structural features, even among prompts within the same category.
