# Windy Translate

**Windy Translate is the developer catalogue of [Windstorm Labs](https://windstormlabs.com)**, part of the [Windstorm Institute](https://windstorminstitute.org). This organisation is the canonical home of our translation models on Hugging Face. Scores, licence and attribution for every model are at **[windytranslate.com](https://windytranslate.com)**.

## What is here

1,660 machine-translation models, one language direction (or language group) per repository:

- 1,607 derived from [OPUS-MT](https://huggingface.co/Helsinki-NLP) (Helsinki-NLP, University of Helsinki), in transformers / safetensors format.
- 53 derived from the [HPLT project](https://huggingface.co/HPLT), in CTranslate2 INT8 format.

Each card says what was changed relative to the upstream model and how that was verified.

## How we score

788 models have a screening score: chrF++ and BLEU on 48 sentences of FLORES-200 dev, measured 2026-08-04. FLORES is professionally translated and is not the data these models were trained on. A 48-sentence screen is not a publication result; treat it as a first filter. Models without a score say so on their card. 53 of those are language-verified with GlotLID, which confirms the output language but says nothing about quality.

## Licensing

Every model keeps its upstream licence: 1,495 are Apache-2.0 and 165 are CC-BY-4.0. Each repository carries the full licence text (`LICENSE`) and an attribution notice (`NOTICE.md`). We did not train the base models; the attribution is there because the licences require it and because the credit is due.
