# Lenitas Core AI Artifacts

Hosted Core AI model artifacts for Lenitas.

This repository contains already-exported Core AI directories that can be downloaded by the Lenitas iOS and macOS app. It does not contain model conversion code.

Core AI assets keep the shape produced by `coreai-models`: either a standalone `.aimodel` directory or a resource bundle directory containing `metadata.json`, one or more `.aimodel` directories, tokenizers, schedulers, and related resources.

## Contents

```text
index.json
artifacts/
  <model-id>/
    <variant>/
      metadata.json
      *.aimodel/
      tokenizer/
```

`index.json` is the app-facing download index. Each entry points to an artifact directory and includes platform support, minimum OS, total size, and per-file SHA-256 checksums.

## Download

The app reads:

```text
https://huggingface.co/lenitas/coreai-artifacts/resolve/main/index.json
```

For each selected artifact, the app downloads files under the entry's `path`, verifies each file, writes into a staging directory, and atomically moves the complete directory into Application Support.

The installed directory is passed to the Core AI runtime or `coreai-models` Swift loader unchanged.

## License

Artifacts may have their own upstream licenses. See each `index.json` entry for license metadata when available.
