ToolMaster-7B

ToolMaster is a framework that shifts tool learning from static imitation to a trial-and-execution paradigm, enabling Large Language Models (LLMs) to actively master tools. It was introduced in the paper Teaching LLMs to Learn Tool Trialing and Execution through Environment Interaction.

Introduction

Existing tool-use paradigms primarily rely on memorizing static solution paths during training, which limits the ability of LLMs to generalize to new or evolving tools. ToolMaster addresses this by training agents to:

1. Trial Phase: Conduct autonomous tool trials to accumulate experiential knowledge.
2. Execution Phase: Perform planning and solving while explicitly employing self-correction to rectify errors based on environmental feedback.

By leveraging Supervised Fine-Tuning (SFT) followed by Reinforcement Learning (RL) using Group Relative Policy Optimization (GRPO), ToolMaster empowers agents to dynamically adapt to unfamiliar tools, significantly enhancing generalization and robustness.
