Key points

  • The authors trained HyInv, a 1.96-million-parameter backbone-conditioned graph network, with random-order autoregressive pretraining followed by structure-reward reinforcement learning.
  • A sampler that drafts at a higher temperature and rewrites at a lower temperature improved refolding TM-score at matched diversity.
  • An optimized implementation with BF16 numerics designs 128 sequences for a 402-residue backbone in 50.6 ms on a single NVIDIA H20 GPU, about 52 times faster than the reference sampler.
  • Across five benchmark datasets and seven dataset-predictor combinations, HyInv reaches a higher average scTM than all ten external baselines at comparable or higher sequence diversity.
  • The average margin is +0.013 over ProteinMPNN and +0.008 over ProteinZero V2.
  • The same default setting supports de novo backbones, pocket-constrained libraries, enzyme redesign with the catalytic site kept, and loop redesign.
