The Sequence Research #495: Microsoft's Framework for Building Large Action Models
An architecture reference and framework for building models that can execute actions.
Action execution is one of the key building blocks of agentic workflows. One of the most interesting debates in that are is whether actions are executed by the model itself or by an external coordination layer. The supporters of the former hypothesis have lined up behind a theory known as large action models(LAMs) with projects like Gorilla or Rabbit r1 as key pioneers. However, there are still only a few practical examples of LAM frameworks. Recently, Microsoft Research published one of the most complete papers in this area outlining a complete framework for LAM models. Microsoft’s core idea is to simply bridge the gap between the language understanding prowess of LLMs and the need for real-world action execution.
