+# GPT-2 (OpenAI / HuggingFace) — xaitalk mirror
+
+This is a **bit-identical mirror** of the canonical artifact from OpenAI / HuggingFace.
+
+The mirror exists only as a resilience fallback for the
+[xaitalk](https://github.com/xaitalk/xaitalk) library — the upstream remains
+authoritative. All credit and licensing for the model belong to the original
+authors.

+## How xaitalk loads this file
+
+```python
+from xaitalk.hub import ensure_model
+weights_path = ensure_model("gpt2")
+# 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`.
