NESTFUL: A Benchmark for Evaluating LLMs on Nested Sequences of API Calls

EMNLP 2025

The resurgence of autonomous agents built using large language models (LLMs) to solve complex real-world tasks has brought increased focus on LLMs’ fundamental ability of tool or function calling. At the core of these agents, an LLM must plan, execute, and respond using external tools, APIs, and cus

Granite-Function Calling Model: Introducing Function Calling Abilities via Multi-task Learning of Granular Tasks

EMNLP 2024industry

An emergent research trend explores the use of Large Language Models (LLMs) as the backbone of agentic systems (e.g., SWE-Bench, Agent-Bench). To fulfill LLMs’ potential as autonomous agents, they must be able to identify, call, and interact with a variety of external tools and application program i…

Who Knows the Answer? Finding the Best Model and Prompt for Each Query Using Confidence-Based Search

AAAI 2024technical

There are increasingly many large language models (LLMs) available to the public. While these LLMs have exhibited impressive abilities on a variety of task, any individual LLM in particular may do well on some tasks and worse on others. Additionally, the performance of these models is heavily depend…

Towards large language model-based personal agents in the enterprise: Current trends and open problems

EMNLP 2023long findings

There is an emerging trend to use large language models (LLMs) to reason about complex goals and orchestrate a set of pluggable tools or APIs to accomplish a goal. This functionality could, among other use cases, be used to build personal assistants for knowledge workers. While there are impressive…
