Large language models support the UI Agents and prompting capabilities.

LLMs are not simply chat engines—they are decision-making systems that interpret goals, reason over dynamic interfaces, and drive autonomous browser workflows. This shift from conversational intelligence to action-oriented reasoning is what enables resilient, adaptive, and maintainable web automation at scale for the UI Agents.

UI Agents offers two models to choose from. Consider the following before using them.
  • Automation Anywhere Narada is recommended and some setup is required. See, Set up Narada for UI Agents
  • No additional manual steps are needed to use Amazon Nova Act. It runs in the existing Google Chrome application on the Bot Runner machine and operates on a unsigned Chrome profile.
