We find that scalable RCT and GNN-based charge models described are likely acceptable extensions of established partial charging methods such as AM1-BCC. We first show that the RCT library charges are viable proxies to the widely-used AM1-BCC with ELF10 conformer selection; we then use RCT charges to assess Espaloma-generated GNN charges for larger systems and highlight structural charge motifs which differ between the methods.
