An 80M RNA model reuses one core four times and beats Evo 2 40B on 70 fitness assays
Eco-RNA turns inference depth into a selectable resource: one 80M-parameter checkpoint applies a shared core repeatedly, lifting aggregate absolute Spearman correlation on the 70-assay RNAGym fitness benchmark from 0.242 to 0.286 and passing Evo 2 40B at four iterations.
