What it is
Weights for Protenix, an open reproduction of AlphaFold 3 that predicts the 3D structure of
proteins, nucleic acids and their complexes with ligands. The upstream URL above is the one
protenix/web_service/dependency_url.py names at tag v0.5.0.
Why this mirror exists
Upstream serves this file from a single Volcengine bucket in Beijing. A network that cannot route there gets a TCP connection that is accepted and then sends nothing, so an install hangs rather than failing. This copy is the same bytes from a host that answers from anywhere. Upstream stays the fallback, not the only door.
Published so tt-bio can fetch it, which runs Protenix on Tenstorrent accelerators. Nothing about the file is tt-bio specific: any Protenix install can use it.

# 9ea20b0aba42f2256711da1d0cd081510a4b291e64375bff6b70ced70b87a5f1
That hash was taken from a fresh upstream download and compared against this copy.
Use it
With tt-bio, nothing to do: tt-bio predict --model protenix-v1 <fasta> fetches from here.
By hand, for an upstream Protenix install:
huggingface-cli download moritztng/protenix-v0.5.0 model_v0.5.0.pt --local-dir .
