ESM-2 t6 8M (Meta FAIR) — xaitalk mirror

This is a bit-identical mirror of the canonical artifact from Meta AI / FAIR.

The mirror exists only as a resilience fallback for the xaitalk library — the upstream remains authoritative. All credit and licensing for the model belong to the original authors.

How xaitalk loads this file

from xaitalk.hub import ensure_model
weights_path = ensure_model("esm2-t6-8m-pt")
# Tries the canonical upstream first; falls back to this xaitalk mirror
# automatically if upstream is unreachable.

Why mirror?

xaitalk's research-grade reproducibility claim relies on every weight file being recoverable years from now. We mirror artifacts ≤ 2.5 GB under xaitalk/*-mirror so the pipeline survives upstream URL changes, repo renames, or deletions. Bit-level parity with the canonical is asserted in CI via python -m xaitalk.hub verify-mirrors.
