To Call or Not to Call: A Framework to Assess and Optimize LLM Tool Calling

arXiv:2605.00737v2 Announce Type: replace Abstract: Agentic AI architectures augment LLMs with external tools, unlocking strong capabilities. However, tool use is not always beneficial; some calls may be redundant or even harmful. Effective tool use, therefore, hinges on a core LLM decision: whether to call or not call a tool when performing a task. This decision is particularly challenging for web search tools, where the benefits of external information depend on the model's internal knowledge and its ability to integrate potentially noisy tool responses. We introduce a principled framework i

Why this matters
Why now

The paper addresses a critical challenge in the rapidly evolving field of AI agents, where practical deployment necessitates more robust and efficient tool-calling mechanisms.

Why it’s important

Improving LLM tool-calling efficiency and reliability directly impacts the performance, safety, and economic viability of autonomous AI systems, which are increasingly central to enterprise operations.

What changes

This framework offers a principled method to evaluate and optimize when LLMs should engage external tools, potentially leading to more deliberate and effective agentic AI behavior rather than indiscriminate tool use.

Winners
