Migrating from ModernMT to Lara Translation API

If you're currently using ModernMT to power your translation workflows, this article walks you through what's changing, what stays the same, and how to get started with Lara

Why Lara?

Lara is Lara's next-generation translation platform. It combines the speed of traditional Machine Translation with the fluency and adaptability of Large Language Models - giving you higher-quality translations that improve over time as you build up your Translation Memories and glossaries.

 

What stays the same

Most of your existing assets and workflows carry over seamlessly:

  • Translation Memories - your existing TMs are fully compatible with Lara. You can continue importing TMX files and using memories to adapt translation output in real time.
  • Glossaries - your terminology lists work in Lara just as they do in ModernMT.
  • Core translation parameters - source language, target language, format, and priority all map directly to Lara equivalents.

What's new

Beyond the migration, Lara unlocks capabilities that weren't available in ModernMT:

  • Style control - enforce formal or informal tone across your translations.
  • Audio translation - speech-to-speech translation with voice options.
  • Image translation - translate text embedded in images with graphical reproduction.
  • Instruction-based adaptation - guide translation style and terminology using natural language instructions alongside your TMs.

What changes for developers

The main technical difference is the authentication flow: Lara uses a JWT token system instead of a persistent API key. Your developers will need to update the auth logic in your integration. Everything else — translation requests, TM management, glossaries — follows the same structure with minimal parameter changes.

For the full technical mapping between ModernMT and Lara endpoints, see the Migration Guide on the Developer Hub.
