opus-mt-en-ROMANCE

Overview

This repository contains an ONNX export of Helsinki-NLP/opus-mt-en-ROMANCE, a Marian machine translation model for translating English into Romance languages.

Source

ONNX source repository: onnx-community/opus-mt-en-ROMANCE

Base model: Helsinki-NLP/opus-mt-en-ROMANCE

The upstream base model is a Transformers-compatible Marian model with source language en and target language group roa.

Intended Use

Use these ONNX model files for English-to-Romance-language machine translation experiments or integration work.

Target Languages

The tokenizer configuration lists Romance-language targets including French, Walloon, Franco-Provencal, Occitan, Catalan, Romansh, Ladin, Friulian, Ligurian, Lombard, Spanish variants, Portuguese variants, Galician, Ladino, Aragonese, Mirandese, Italian, Corsican, Neapolitan, Sicilian, Venetian, Sardinian, Romanian, and Latin.

Training Data

Not documented in this ONNX repository. See the upstream Helsinki-NLP base model documentation for training details.

Evaluation

No ONNX-specific evaluation or parity results are documented in this repository.

Limitations

• This is not a Spanish-to-Portuguese-only model; it translates from English to a Romance-language target group.
• ONNX runtime compatibility and parity with the upstream Transformers model are not documented here.
• Translation quality can vary by target language, domain, and decoding configuration.
