-A Hugging Face Spaces app that translates English text to ~400 languages using Google's [MADLAD-400](https://arxiv.org/pdf/2309.04662) 3B Seq2Seq model. Built with Gradio and deployed on HF Spaces. Falls back to CPU with a warning when no GPU is available.

 **`app.py`** — Single-file application. Uses `@lru_cache` for lazy loading of the `google/madlad400-3b-mt` tokenizer and model with `float16` precision (no download on import). Translation prepends a language token to the input text (e.g., `<2fr>Hello`) before tokenization and generation. The `@spaces.GPU` decorator allocates GPU on HF Spaces infrastructure.
 
-**`langmap/`** — Package with `langid_mapping.py`, a hand-maintained dictionary mapping ~400 language tokens to human-readable language names (sourced from pages 16–21 of the MADLAD-400 paper). Available languages at runtime are the intersection of this mapping and the model's vocabulary.

Available languages at runtime are the intersection of this mapping and the model's vocabulary.
 
 **`tests/`** — Pytest suite split into fast (`test_langmap.py`) and slow (`test_app.py`). Slow tests require GPU and model download; they are auto-skipped without MPS/CUDA. Fast tests in `test_app.py` verify the module imports without triggering model download.
