Get scale and quality

Machine translation is great when it works - it scales.

But human language is difficult for machines. Machine translation fails often and unpredictably. The results can be nonsensical, misleading, offensive or even dangerous.

Now you can safely auto-approve raw machine translation.

ModelFront risk prediction technology is the key to hybrid translation, quality evaluation and much more.

All languages

As billions of users join the internet, platforms expand to support hundreds of languages.

ModelFront loves the chaos. The approach supports all of the top ten thousand language pairs.

All content types

ModelFront supports product titles, descriptions and reviews, emails, technical documents, marketing material, subtitles or UI strings.

The production-strength system is built to work for all verticals — from fashion, gaming, social and travel to hardware, automotive and defense.

All engines

It works with any translation system, like those from Google, Microsoft, Yandex (Яндекс), Baidu (百度), IBM, DeepL and ModernMT.

And it even works with custom-trained or pre-trained models like AutoML, Fairseq and Marian.

Use cases

There are many ways for you to apply the linguistic knowledge, innovative research and scalable infrastructure at the core of ModelFront.


Better training data is key to better machine translation.

ModelFront is an easy and robust way to filter parallel corpora for training better custom machine translation.


Are you estimating post-editing effort, comparing engines or training or building your own?

ModelFront correlates with human evaluation and beats BLEU on accuracy and convenience - no reference translations required.

Automated evaluation is a game-changer for everyone from linguists to machine translation researchers.

Hybrid translation

Do you need to translate at quality and scale?

ModelFront catches critical errors in machine translation to let you balance machine scale and human quality.

Hybrid translation can be orders of magnitude faster than traditional post-editing.


Checking final human translations is almost as much work as translation itself.

ModelFront makes it super easy to sort by risk for quick and targeted final validation.

Integrated with the top translation APIs

ModelFront integrations support custom models and adaptive systems like Google AutoML, Microsoft Custom Translator and ModernMT.

How our technology fits in

Gartner, the world's leading research and advisory company, published its 2020 Market Guide for AI-Enabled Translation Services.

"Advances in artificial intelligence (AI) are enabling a broad range of new use cases, enabling translations that were previously not possible due to cost or delays"

It lists key players in machine translation technology, among them Systran, Google, Microsoft, Amazon, Unbabel and ModelFront.

"Many enterprises are not aware of the emerging AI-enabled translation services and their capabilities, and as a result are not achieving the savings and efficiencies these might offer"

Gartner features ModelFront as the first and only provider of translation risk prediction.

"Value to enterprises: The solution can be used to automate translation post-editing workflows, and aggregate decision-making and offline tasks."

Visit us in Silicon Valley in 2022

The TAUS Massively Multilingual Conference & Expo 2022 will be held in the San Francisco Bay Area in November.

The panel on cutting-edge machine translation technology brings together leaders from ModelFront, Amazon, Systran, Google and Apple.

John DeNero, the CTO of Lilt, will grill them on massively multilingual approaches, customization marketplaces, risk prediction and more.

Supporting open research

ModelFront is built on decades of open research and open-source technology.

ModelFront supports open research on machine translation and quality estimation.

Novel datasets

I-Q-Tel Labs partnered with ModelFront to provide top-quality data for the WMT 2020 Quality Estimation Shared Task.

The labeled dataset designed by Nina Lopatina, now VP of Data Science at I-Q-Tel, featured user-generated content - a challenge for machine translation, quality estimation and human linguists.

10000 sentences were translated from Russian to English by a Fairseq model and labelled by ModelFront human linguists according to Facebook AI Research FLORES guidelines.

Open evaluations

Better training data is key to better machine translation. The young research lab YerevaNN used ModelFront and took first place in WMT 2020 Russian-English biomedical translation task.

ModelFront openly filters open datasets for the community, from the TAUS Corona Crisis Corpus to the latest conference competition datasets. Open evaluations are free and easy to browse, filter and download.

For WMT 2021, ModelFront has added hundreds of datasets with tens of millions of translations, supporting better machine translation for languages from Afrikaans to Zulu.
