Microsoft's Large Action Model (LAM) is an advanced AI designed to perform tasks directly in Windows applications like Word, Excel, and PowerPoint by interpreting and executing user instructions. Trained using step-by-step plans and real actions, LAM outperforms general AI models like GPT-4 by automating complex workflows and interacting with GUI elements in real time.
By combining supervised fine-tuning, imitation learning, and reinforcement learning, Microsoft aims to revolutionize computer automation, making AI more efficient at handling everyday tasks across different apps.
