<ul data-eligibleForWebStory="true"><li>The OSI model, originally for network protocols, influenced how engineers structure complexity with its seven-layer abstraction.</li><li>As autonomous agents become more advanced, a new layering model is needed to focus on goals, memory, actions, and reasoning.</li><li>The new model maps the OSI layers to LLM-powered agentic systems instead of TCP/IP.</li><li>At the top of the new model is the Application Layer where agents have goals like generating reports or booking meetings.</li><li>Prompt assembly, structured tool calls, and knowledge encoding take place in the Presentation Layer of the new model.</li><li>Memory and partial reasoning activities are managed in the Session Layer of the reimagined model.</li></ul>
