AgentSynth: Scalable Task Generation for Generalist Computer-Use Agents

Summary

This paper talks about AgentSynth, a system that uses large language models to create lots of different computer tasks and step-by-step actions for AI agents that are designed to use computers in many ways.

What's the problem?

The problem is that teaching these general AI agents requires many tasks and detailed instructions, which usually need a lot of time-consuming and expensive human work to create.

What's the solution?

The researchers made AgentSynth, which automatically generates diverse and high-quality task examples along with detailed steps by breaking tasks down into smaller parts and using language models to build them up. This method allows for controlling how hard the tasks are and reduces the need for costly human labeling.

Why it matters?

This matters because it helps develop versatile AI agents faster and cheaper, allowing them to learn how to perform many different computer-based tasks, which can be useful in automating many everyday digital activities.

Abstract

AgentSynth synthesizes high-quality, diverse tasks and trajectory datasets for generalist computer-use agents using LLMs and an iterative subtask construction approach, enabling precise control over task complexity and offering significant cost savings compared to human annotations.
