# Two-Way Polish 🇵🇱↔️🇬🇧 English Translator with ByT5

This Space provides two-way translation between Polish and English using a single, powerful model: **Google's `byt5-300m`**.

The key feature of this model is that it is **tokenizer-free**. It operates directly on raw text bytes (UTF-8) instead of relying on a fixed vocabulary. This makes it incredibly robust for translation, as it can handle any character, including:
*   Polish diacritics (`ą`, `ć`, `ę`, `ł`, `ń`, `ó`, `ś`, `ź`, `ż`)
*   Emojis and special symbols
*   Typos or unusual spellings

## How to Use

1.  **Enter your text:** Type or paste the text you want to translate.
2.  **Select the direction:** Choose either `English to Polish` or `Polish to English`. The application adds a special prefix to the text to tell the model which way to translate.
3.  **Click Submit:** The translated text will appear in the output box.

## Model and Technical Details

This application is powered by a fine-tuned version of the `google/byt5-300m` model.

*   **Model:** [google/byt5-300m](https://huggingface.co/google/byt5-300m)
*   **Architecture:** ByT5 (Byte-level T5) is a "tokenizer-free" model that processes text as a sequence of bytes. This eliminates "unknown token" errors and allows a single model to handle multiple tasks and languages flexibly.
*   **Method:** Two-way translation is achieved by prepending a task-specific prefix to the input before feeding it to the model (e.g., `translate English to Polish: Hello world!`).
