Translate-R1: Cost-Aware Translation Tool Use via Reinforcement Learning

arXiv:2606.06835v1 Announce Type: new Abstract: The performance gap across languages in LLMs is well documented, and closing it natively requires pretraining or fine-tuning on corpora that, for most languages, do not exist. Translation offers an alternative: converting an input into the model's dominant language unlocks its full capabilities at once. Applying translation to every input, however, is wasteful for languages the model already handles, while leaving the choice to the model fails in the opposite way, as LLMs are overconfident and skip the tool even when they cannot understand the in

Why this matters
Why now

The proliferation of Large Language Models (LLMs) and the recognized performance gap across languages make this a timely exploration of efficient multilingual AI deployment.

Why it’s important

This research addresses a critical limitation of current LLMs by proposing a cost-effective method to bridge language barriers, enhancing the utility and global reach of AI systems.

What changes

AI models can now dynamically decide when to use translation tools, optimizing performance and resource consumption for diverse language inputs without manual intervention.
