Capability-Aligned Hierarchical Learning for Tool-Augmented LLMs

arXiv:2606.09371v1 Announce Type: new Abstract: Tool learning enables LLMs to invoke external tools to accomplish tasks. Prior studies have demonstrated the effectiveness of a hierarchical structure: a high-level policy handles global planning and decomposes tasks into manageable sub-tasks, and a low-level policy focuses on invoking tools to solve these sub-tasks. However, these works typically optimize the high-level and low-level policies separately, leading to planner-executor misalignment and limiting LLM performance on tool-use tasks. In this paper, we propose a method called Capability-A

Why this matters
Why now

The rapid advancement of large language models is driving the need for more sophisticated and efficient ways for them to interact with external tools, moving beyond basic integration.

Why it’s important

This development addresses a critical bottleneck in the real-world application of tool-augmented LLMs, promising more robust, reliable, and autonomous AI agents.

What changes

The proposed hierarchical learning method aims to resolve 'planner-executor misalignment' in tool-augmented LLMs, suggesting a more integrated and effective framework for AI agent development.
