IgT5 Paired

IgT5 Paired encodes antibody variable-region heavy–light chain pairs into contextual embeddings trained on millions of paired sequences from Observed Antibody Space. The encoder endpoint supports GPU-accelerated batches of up to 8 items, each with heavy and light chains up to 256 residues, or a single unpaired sequence up to 512 residues. It returns mean and/or per-residue embeddings per input, enabling downstream models for binding affinity or expression prediction and antibody engineering tasks that require cross-chain representations.
