# atlas-associates/TranslateGemma-4B-IT

This repository is a **mirror / redistribution** of [`litert-community/TranslateGemma-4B-IT`](https://huggingface.co/litert-community/TranslateGemma-4B-IT) provided under the [Gemma license](https://ai.google.dev/gemma/terms).

## Why this mirror exists

[Arc](https://www.atlasassociates.io/) — a privacy-first end-to-end-encrypted messenger — uses TranslateGemma 4B as the on-device translation engine ("Rosetta") via the `flutter_gemma` package + MediaPipe LLM Inference. The upstream `litert-community` repository is **gated** (requires a Hugging Face login + Gemma license acknowledgement per user). Distributing the model through this mirror lets Arc download the model from end users' devices without bundling a Hugging Face access token in the Arc app or in app-config Firestore.

By downloading the model file from this mirror, you implicitly accept the upstream Gemma license terms. Atlas Associates Inc. acts only as a distribution mirror; the model weights are the property of Google.

## Files

| File | Size | Format | Notes |
|---|---|---|---|
| `translategemma-4b-it-int8-web.task` | ~3.63 GiB | MediaPipe LiteRT `.task` (int8, GPU/CPU) | Verbatim copy of the upstream file (`sha256` matches upstream). |

## Usage

This file is consumed by the [`flutter_gemma`](https://pub.dev/packages/flutter_gemma) package via:

```dart
await FlutterGemma.installModel(modelType: ModelType.gemmaIt)
    .fromNetwork(
      'https://huggingface.co/atlas-associates/TranslateGemma-4B-IT/resolve/main/translategemma-4b-it-int8-web.task',
      foreground: true,
    )
    .install();
```

The model runs entirely on-device — no data is sent to any server during inference. See [Rosetta on-device translation in Arc](https://www.atlasassociates.io/arc) for the user-facing product context.
