CRAFT: Customizing Large Language Models with Tool Creation and Retrieval Framework

Core Concepts

CRAFT introduces a framework for creating and retrieving tools to customize LLMs for diverse tasks, showcasing improved performance across various domains.

Abstract

CRAFT presents a novel approach to augmenting LLMs with specialized tools through tool creation and retrieval. The framework focuses on generating diverse, reusable, and correct tools tailored to specific tasks. By abstracting specific solutions into general-purpose tools, CRAFT enhances the reusability of the toolset. The retrieval component employs multi-view matching to identify relevant tools during inference, leading to improved performance in challenging tasks like visual question answering, tabular processing, and mathematical reasoning. Experiments demonstrate substantial enhancements compared to baseline methods across different datasets.

Deeper Inquiries

How does CRAFT's approach compare with existing methods for tool learning with LLMs

CRAFT's approach differs from existing methods for tool learning with LLMs in several key aspects. Firstly, CRAFT focuses on creating a specialized toolset tailored to specific tasks by generating diverse, reusable, and correct tools through an iterative process of sampling problems and abstracting code solutions. This contrasts with approaches that rely on limited examples or lack reusability in the created tools.
Secondly, CRAFT incorporates a retrieval component that effectively retrieves relevant tools from the large constructed toolset during inference time. This multi-view matching strategy considers the target problem, function names, and docstrings to identify and utilize appropriate tools for enhancing LLM performance. In comparison, other methods may rely on pre-selected tools or heuristic-based strategies for tool selection.
Furthermore, CRAFT's framework is designed to be flexible and adaptable across various domains and tasks without extensive fine-tuning. It offers a training-free approach where off-the-shelf LLMs can be customized using the created toolsets without additional training data or model adjustments. This plug-and-play feature sets it apart from approaches that may require more manual intervention or domain-specific tuning.

What are the implications of CRAFT's scalability as the toolset size increases

The scalability of CRAFT as the toolset size increases has significant implications for its effectiveness in enhancing LLM performance across different tasks. As demonstrated in experiments where the size of the toolset was varied by including tools from different epochs of creation, there was a consistent improvement in soft accuracy as the toolset expanded.
This scalability indicates that as more diverse and specialized tools are added to the repository, LLMs can benefit from a wider range of problem-solving capabilities without sacrificing performance quality. The upward trend observed suggests that further expansion of the toolset could lead to continued enhancements in task performance.
Additionally, scaling up the toolset allows for greater coverage of problem types and complexities within various domains. With a larger pool of tools at their disposal, LLMs can access more nuanced solutions to address intricate challenges effectively.
