ToolSense is a novel diagnostic framework for evaluating the parametric tool knowledge embedded within large language models (LLMs). This framework allows for a comprehensive audit of how LLMs comprehend and interact with various external tools. It offers critical insights into the functional aptitude of these advanced AI systems.

The development of ToolSense is part of ongoing research to enhance our understanding of LLM capabilities. By providing a structured method for assessment, researchers can better identify strengths and weaknesses in an LLM's tool-use reasoning. This contributes to the creation of more robust and reliable AI applications.

This framework is introduced in a paper titled "ToolSense: A Diagnostic Framework for Auditing Parametric Tool Knowledge in LLMs," co-authored by Ashutosh Hathidara and others. The full text of this paper is available through arXiv, providing detailed information on the methodology and findings. Further details and related resources, including code and data, are accessible via platforms such as alphaXiv and Hugging Face.
