Large Action Model

Definitions

1. A model or system designed not just to generate text but to choose and execute actions across tools, interfaces, or environments. The term is used in discussions about agentic systems that interact with software or the physical world.

   In plain English: An AI model aimed at taking actions, not just generating text.

   Example: "They framed the browser automation agent as a large action model because its value came from completing workflows, not from writing prose."
