atlas-associates/TranslateGemma-4B-IT

This repository is a mirror / redistribution of litert-community/TranslateGemma-4B-IT provided under the Gemma license.

Why this mirror exists

Arc — 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.

Usage

This file is consumed by the flutter_gemma package via:

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 for the user-facing product context.
