OVHaiLLM/FinTranslate-160M

We released the suite of models we trained as part of our work on scaling laws of decoder-only machine translation systems. This work has been published in WMT24 and is available here.

These models have been trained on a mixture of general and financial sentences on 11 language directions. They support 8 languages (English, French, German, Italian, Spanish, Dutch, Swedish and Portuguese) as well as 9 domains (general + 8 financial subdomains). They are not tailored for document-level translation.

A running demo of these models is available on our dedicated space.

Evaluation

The below table details the performance of our models on general domain translation.

The below table details the performance of our models on financial translation.
