Translate-R1: Cost-Aware Translation Tool Use via Reinforcement Learning
Researchers are exploring cost-aware strategies for large language model agents to improve efficiency and performance. One paper introduces a framework for skill rewriting that optimizes for cost by preserving essential operational anchors, leading to reduced agent costs. Another study focuses on cost-aware translation tool use, developing a reinforcement learning policy that intelligently decides when to translate inputs to leverage LLM capabilities without unnecessary expense, particularly benefiting low-resource languages. A third paper presents a reinforcement learning framework for source rewriting in machine translation that directly optimizes for downstream translation quality, outperforming prompt-based methods.
