About this model
The first thing anyone computes on a new sequence. Amino acid composition, molecular weight, theoretical pI, GRAVY hydropathy index, aromaticity, net charge and the A280 extinction coefficient — all closed-form, all instant, all free. Values follow the ExPASy ProtParam definitions, so they are directly comparable with the tool your lab already uses.
Standardized I/O contract
Every model in the Hub speaks the same contract, which is what lets the Router and the agent call any of them without special-casing.
