# 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`.
