Boltz-2 weights (tt-bio mirror)

Mirror of the Boltz-2 structure- and affinity-prediction weights, packaged for use with tt-bio on Tenstorrent hardware. The files are byte-for-byte identical to the upstream Boltz-2 release; this repo simply hosts them on the Hugging Face Hub so tt-bio can fetch them with huggingface_hub like every other model it runs.

Files

File	Description
boltz2_conf.ckpt	Boltz-2 structure / confidence model
boltz2_aff.ckpt	Boltz-2 binding-affinity model
mols.tar	CCD molecule / component library used during featurization

Usage

tt-bio downloads these automatically:

tt-bio predict examples/prot.yaml --model boltz2 --use_msa_server --override

Or fetch a single file directly:

from huggingface_hub import hf_hub_download
path = hf_hub_download("moritztng/boltz-2", "boltz2_conf.ckpt")
