Characterizing Web Search by Conversational LLM Agents: From Search Decisions and Strategies to Results and Responses

Mahsa Amani, Seungeon Lee, Abhisek Dash +9

Conversational LLM agents increasingly rely on Web search, yet the end-to-end lifecycle of agentic search remains poorly understood. We present the first study of Web search across…

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

Qinyuan Wu, Soumi Das, Mahsa Amani +5

Agentic AI architectures augment LLMs with external tools, unlocking strong capabilities but potentially incurring substantial costs. Moreover, tool use is not always beneficial: r…

In Agents We Trust, but Who Do Agents Trust? Latent Source Preferences Steer LLM Generations

Mohammad Aflah Khan, Mahsa Amani, Soumi Das +5

Agents based on Large Language Models (LLMs) are increasingly being deployed as interfaces to information on online platforms. These agents filter, prioritize, and synthesize infor…

Rote Learning Considered Useful: Generalizing over Memorized Data in LLMs

Qinyuan Wu, Soumi Das, Mahsa Amani +4

Rote learning is a memorization technique based on repetition. Many researchers argue that rote learning hinders generalization because it encourages verbatim memorization rather t…

Revisiting Privacy, Utility, and Efficiency Trade-offs when Fine-Tuning Large Language Models

Soumi Das, Camila Kolling, Mohammad Aflah Khan +5

We study the inherent trade-offs in minimizing privacy risks and maximizing utility, while maintaining high computational efficiency, when fine-tuning large language models (LLMs).…
