# WindyWord.ai Translation — Portuguese → English

**Translates Portuguese (`pt`) text into English (`en`).**

## Quality & Model Lineage

- **Tier:** Standard ⭐⭐⭐⭐
- **Base model:** [Helsinki-NLP/opus-mt-ROMANCE-en](https://huggingface.co/Helsinki-NLP/opus-mt-ROMANCE-en) — 68k+ downloads, multilingual Romance-source model
- **Architecture:** MarianMT
- **Note:** Helsinki-NLP does not publish a dedicated Portuguese-only `opus-mt-pt-en` model. Their canonical path for Portuguese-source translation is the multilingual `opus-mt-ROMANCE-en`, which handles Portuguese alongside Italian, Spanish, French, Catalan, and Romanian as source languages. This WindyWord repo wraps the same underlying weights with a Portuguese-specific repo name to satisfy installer / consumer code that expects a `translate-pt-en` artifact.

For sibling Romance-source pairs use [WindyWord/translate-ROMANCE-en](https://huggingface.co/WindyWord/translate-ROMANCE-en) directly (same underlying model).

## Available Variants

| Variant | Description |
|---|---|
| `lora/` | **WindyStandard** — production baseline. Helsinki-NLP/opus-mt-ROMANCE-en weights wrapped under the WindyWord pt-en namespace. |

## Quick Usage

```python
from transformers import MarianMTModel, MarianTokenizer
tokenizer = MarianTokenizer.from_pretrained("WindyWord/translate-pt-en", subfolder="lora")
model = MarianMTModel.from_pretrained("WindyWord/translate-pt-en", subfolder="lora")
```
