Booking.com launches ModelFront to scale human-quality translation
October 8, 2025
- Booking.com has launched ModelFront to help scale translation while maintaining human quality.
- ModelFront provides AI to scale translation, and keep human quality, to large translation buyers.
ModelFront, the provider of AI to scale human-quality translation, today announced that it has rolled out its AI system for Booking.com.
Booking.com, the world's leading provider of online travel, was early to start using AI to generate a translation, and is accessible in more than 40 languages.
“AI for generating translation radically improved over the past decade, so why didn’t the world get radically more human-quality content in more languages?”
— Paula Manzur, language AI strategy lead at Booking.com
Unlike AI that just generates translation, ModelFront provides AI to check and fix translations that AI generates.
With better generation alone, translation was either too slow because it still required manual verification of every single word, or too low-quality.
With AI for verification, combined with AI for generation, large translation buyers have accelerated translation significantly, while keeping human quality.
At the top translation industry event, leading luxury fashion marketplace Farfetch shared that it achieved a 5x speedup with ModelFront quality prediction and automatic post-editing.

About AI and translation
Translation is a benchmark for AI progress.
The Transformer model architecture at the heart of genAI (generative artificial intelligence) was first invented inside Google Research for Google Translate in 2017, and quickly rolled out in production.
Translation was the first job to shift from writing from scratch, to editing the output of AI. Since then, the human translation industry has grown by an order of magnitude, to more than $75 billion in 2025.
Now translation is leading again, with AI for verification that works in the real world.
Translation is also an important challenge for humanity. More than 6 billion people around the world cannot understand English.
