# OpenAI CLIP ViT-L/14@336px checkpoint (mirror)

Byte-identical mirror of [`openai/CLIP`](https://github.com/openai/CLIP), checkpoint served from `openaipublic.azureedge.net` 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 2026-09-04 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

The `openai/CLIP` repository is published under the MIT License, Copyright (c) 2021
OpenAI (`LICENSE`, verbatim). OpenAI publishes this checkpoint through that
repository's `clip.load("ViT-L/14@336px")` loader (served from
`openaipublic.azureedge.net`; the sha256 is the hash OpenAI encodes in the download
URL) without a separate licence statement for the weights, and OpenAI's own Hugging
Face copies (for example `openai/clip-vit-large-patch14-336`) carry no licence tag.
The file is redistributed here unchanged, as released; the `license: unknown` tag
reflects that no explicit licence statement covers the weights. If you are a rights
holder and object to this redistribution, open a discussion on this repository and
the file will be taken down.

## Usage with Cuvis.AI

```text
uv run download-model download clip_vit_l_14_336
```

`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-adaclip` 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.
