| # RoBERTa-large (mirror) |
|
|
| Byte-identical mirror of [`FacebookAI/roberta-large`](https://huggingface.co/FacebookAI/roberta-large) at revision `722cf37b1afa9454edce342e7895e588b6ff1d59` (original release: <https://github.com/facebookresearch/fairseq>) for the |
| [Cuvis.AI](https://github.com/cubert-hyperspectral/cuvis-ai) plugins. No fine-tuning, |
| conversion or re-serialization: the files below are the upstream release as published, |
| with the upstream licence text in `LICENSE`. |
|
|
| ## Why this mirror exists |
|
|
| Cuvis.AI provisions model weights once into a shared cache (`download-model download |
| <name>` from `cuvis-ai-core`) and then runs its pipelines in an offline, token-free |
| runtime that only reads that cache. Hosting the exact upstream files under the |
| `cubert-gmbh` organisation makes that provisioning reproducible (commit-pinned and |
| sha256-verified) and takes the per-user Hugging Face account and token out of the |
| users' path. |

| Mirrored on 2026-10-09 by Cubert GmbH from the sources above. The sha256 values are the |
| upstream values; `tools/mirror_weights.py check` in `cuvis-ai-core` re-verifies this |
| repository against them and against the upstream licence text. |
|
|
| ## Licence |
|
|
| MIT License. The `LICENSE` file is the upstream licence text taken verbatim from |
| <https://github.com/facebookresearch/fairseq> (where RoBERTa was released; the Hugging Face repository declares `license: mit` and ships no LICENSE file) at the mirror date. Copyright remains with the upstream authors; Cubert GmbH |
| claims no rights in these files. |
|
|
| ## Usage with Cuvis.AI |
|
|
| ```text |
| uv run download-model download roberta_large |
| ``` |
|
|
| `download-model` (from `cuvis-ai-core`) provisions the file into the shared Hugging |
| Face cache and verifies its sha256. From cuvis-ai-core 0.16.0 on, |
| `ModelWeights.resolve("<name>")` returns the cached path and the `cuvis-ai-steervit` nodes |
| resolve their weights through it, so a pipeline needs no manual step once the |
| weights are provisioned; earlier plugin releases still fetch from their original |
| upstream sources. |
