Analysis
This paper introduces Youtu-Agent, a modular framework designed to address the challenges of LLM agent configuration and adaptability. It tackles the high costs of manual tool integration and prompt engineering by automating agent generation. Furthermore, it improves agent adaptability through a hybrid policy optimization system, including in-context optimization and reinforcement learning. The results demonstrate state-of-the-art performance and significant improvements in tool synthesis, performance on specific benchmarks, and training speed.
