Getting started

To get started with ModelFront, sign up to get an API key and access to the console. Then you're ready to hit our REST API.


The ModelFront console is a quick and effective way to try translation risk prediction and understand your own translation risks by graphing, slicing and monitoring ModelFront's aggregate predictions.


The risk API provides real-time risk predictions on each machine translation. You get a risk prediction score between 0.0 and 1.0 on each machine translation, typically a sentence or a phrase. You set your own quality threshold to you control the balance of quality, scale and speed.

It also works with custom-trained models like those from Google AutoML and Microsoft Custom Translator, which are key to many of the applications successfully using machine translation at scale.


ModelFront automatically improves as you use it. You can also add your own monolingual data, parallel data or labelled data to boost accuracy quickly and accelerate the rate at which ModelFront improves on your data.


ModelFront risk prediction API calls are charged by the character. There is a discount for prepaid calls. The console and uploading data are free.

We can silo your proprietary data, but we do not support on-premise deployment.
